Valve Type Comparisons

rainbird water efficient rotary nozzleWelcome to the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to offer our online readers some news, tips and advice concerning sprinkler irrigation here in the Central Florida area. Today we would like to explain the pros and cons of different valve types for sprinkler irrigation systems.

A gate valve is a general service valve used primarily for on/off, non-throttling service. The valve is closed by a flat face, vertical disc, or gate that slides down through the valve to block the flow.

A ball valve uses a rotating ball with a hole through it that allows straight-through flow in the open position and shuts off flow when the ball is rotated 90 degrees to block the flow passage. It is used for on-off and throttling services.

A butterfly valve controls flow by using a circular disc or vane with its pivot axis at right angles to the direction of flow in the pipe. The butterfly valve is used both for on-off and throttling services.

Latching solenoids do not have a constant source of power to them. These valves use an electric pulse, meaning it has the primary pulse to cut it on but a secondary pulse acting as a switch to cut it off. Sometimes these valves have a tendency to hang up so the zone would be stuck on or inoperational.

In addition to these standard valve products, many valve manufacturers produce custom-designed valves and actuators for specific applications. Valves are available in a broad spectrum of sizes and materials. Each design has its own advantages, and selection of the proper valve for particular application is critical.

Common Sprinkler Repair Solutions

hessenauer-irrigation-service-truckThank you for visiting the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to give our website visitors news, tips and advice concerning sprinkler repair and irrigation here in the Central Florida and Orlando areas. Today we would like to offer some common sprinkler repair solutions for problems that could arise.

One problem could be that water does not come out of the sprinklers when the irrigation system is turned on. This could be a sign of several problems. One of the more common issues is clogged heads or pipes by dirt or debris. Locating that debris and clearing it out is the real challenge.

Leaks in the piping could be an issue. Sprinkler heads can get damaged and cracked by extreme weather, by getting run over by the lawn mower or by someone stepping on them wrong. A broken head may not work at all or may spray water around wildly.

Locate the broken pipe usually by flooding or patches of water in the lawn. Roots can grow and break pipes as well. Repairing this situation could involve the need to dig out around the broken pipe to replace pipe sections or repair the problem. The best way is to leave this to a certified professional rather than taking matters into your own hands.

Sometimes too many sprinkler heads leaking could be the cause of the problem. Leaks can cause puddles to form in your yard, while leaving the areas that you want to water stay dry. Leaks can be caused by faulty installation, a line freezing during a particularly cold winter or damage due to landscaping and other digging. Leaks can also be the result of a faulty valve box.

Fixing a leaking line can be a rather involved lawn sprinkler repair job. If the leak is visible near the sprinkler head, you can try replacing the head and see if that helps. For larger leaks, where water is pooling in the yard or one area is visibly greener than the other parts of the yard, you’ll need to call a professional lawn sprinkler repair company.

If your sprinkler system turns on, but there is just a drizzle coming out of all of the sprinkler heads, there is a possibility too many sprinkler heads running at the same time and demand for water inside of the house can conflict with the demand for water to the sprinkler system.

Without proper knowledge and experience, it can be very difficult to know what exactly is causing the blockage. Your best bet is to always talk to a lawn irrigation contractor to find out what the cause of the problem is.

Drainage Quick Tips

drain attachment to prevent floodingWelcome to the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to inform our online readers about sprinkler irrigation here in Orlando and the Central Florida area. Today we would like to offer our online readers some drainage quick tips that could make life easier.

Flooding by clogged drains can cause problems in the neighborhood. You can help prevent flooding with a few small maintenance actions on your property.

Keep leaves and debris out of the drains and gutters. Be sure to clean the gutters and drainage downspouts attached to your roof twice a year to ensure a well-flowing drainage system. Just a simple clog can lead to larger issues on your property and can be easily avoided by a survey of your gutters and drains.

Avoid piling yard waste such as fallen leaves on your property where it could wash into city drains. Keep yard waste in a waste bin or other container.

Use a rake or broom to remove leaves and debris that may collect on the tops of storm drains, and then place the material in your yard waste container. If the drain is still clogged after you’ve removed the debris, contact your maintenance services.

Inspect for leaks or damage to rain gutters that could cause a flat roof to flood.
Direct flows from downspouts away from your foundation, without discharging flows to adjacent properties.

Controlling Sprinkler Water Pressure

sprinkler irrigation systemThank you for visiting the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to inform our website visitors on sprinkler irrigation and drainage related issues here in Central Florida and Orlando. Today we would like to explain some ways to control the water pressure in your sprinkler system.

Sprinkler system adjustments are an often overlooked part of the installation process, and you should be alert to keep the system adjusted over the years to maximize its efficiency, conserve water and save you money. One way to adjust the sprinkler irrigation system is to regulate the water pressure. There are several ways to control the pressure delivered to the sprinkler nozzle.

Some ways to control pressure delivered to the sprinkler nozzles include:

-adjusting the master valve flow control
-adjusting the flow control on the station valves
-adjusting the radius screw on the top of the nozzle
-installation of a pressure reducing valve on the water supply
-as a last resort only, you can adjust the shut-off valve to close part way, creating a friction loss which will reduce operating pressure. If you’re this desperate, you should have a pressure regulator installed.

If you have a mixture of spray stations and rotor stations, you should adjust the pressure at the rotor stations first. Turn on the largest station and adjust the master valve flow control until the flow control is either closed as far as it will go or the spray stream begins to fall. Then open the flow control back up, slightly until the pattern reaches its full throw radius, then a little more for margin in case your supply pressure drops a few psi in the future.

If you have both rotor and spray stations, and you adjusted the rotor stations in the preceding steps, adjust the remaining spray stations now. Since rotors require higher pressure to operate well, adjustments made up to this point will deliver too much pressure to the spray stations. Adjust each of the spray station valve flow controls by watching the spray pattern droop slightly while closing the flow control, then open it slightly to reach full radius.

If you have adjusted the flow controls as much as you feel comfortable and you still have misting, consider adjusting the radius screw on the top of each sprinkler by turning it clockwise to reduce the flow. This will introduce a friction loss in the nozzle itself, reducing the flow of water. If the pressure was too high to start with, this will reduce misting. If the pressure was OK to start with, this adjustment can reduce the radius.

Fixing Common Irrigation Issues

irrigation grassWelcome to the Hessenauer Sprinkler Repair and Irrigation blog and website. Many homeowners use automated sprinkler irrigation systems to irrigate their lawns and ornamental plants. In addition, nearly all newly built residential properties in Florida are irrigated using automatic systems with permanently installed sprinklers. Although sprinklers are designed to provide minimal maintenance and automated irrigation, some common irrigation issues could arise and need fixing.

Some of the most common irrigation issues include clogged sprinklers, obstructed sprinklers, overspray and pipe leaks or breaks. Although we recommend leaving sprinkler irrigation issues to your trained professional, some of these problems could be easily repaired.

Sprinklers can become clogged by dirt or debris in the filter or nozzle of the sprinkler. When the system is running with a clogged sprinkler, little or no water is able to exit the nozzle. In spray systems, raise and secure the pop-up part of the sprinkler (known as a riser) using a helper or a soft surfaced clamping device. Use minimal force to not damage the riser. Unscrew the top part of the spray head while the water is turned off, and remove the filter from the inside of the sprinkler body. To remove the filter from the body of the sprinkler you may need tweezers or a paper clip. Rinse the filter and spray nozzle off and while the spray is dismantled, the irrigation line should be flushed to ensure no other debris is in the system. Replace the filter and the nozzle, making sure that the spray of water is aimed in the proper direction. Turn on the irrigation and ensure that water spray is reaching the targeted area.

For the rotors, the internals of the rotor need to be removed because the small basket-shaped filter is at the bottom of the rotor body. This can usually be performed by unscrewing the top portion of the rotor from the body using counter clockwise turns. Remove the filter, rinse it thoroughly and while the rotor is dismantled, the irrigation line should be flushed to ensure no other debris is in the system. Use care that dirty water and trash doesn’t drain back into the open rotor body. Replace the filter and nozzle and turn on the irrigation system and adjust the rotor’s coverage pattern if necessary.

Leaks can occur in sprinklers when seals become worn over time. The location of the leak determines how to repair it, and the common places to find a problem is in the rotor or the valves. Some types of rotors allow for replacement of the seal inside the sprinkler. In general, once the sprinkler body has a large leak, the entire sprinkler should be replaced. There are several types of irrigation valves, each having different problems and maintenance requirements. The problems that can cause leaks in valves depend on the type of valve. In general, if the valve has an external crack it will need to be replaced.

Overspray onto sidewalks, streets or buildings can be an issue. Sprinklers require adjustment to ensure water is properly applied to the right areas. If a street or house is wet after an irrigation cycle, the irrigation system should be evaluated and modified so that water is applied only to the landscape. A common problem is incorrectly positioned sprinklers. They can be slightly tilted so that the irrigation is not directed towards the target area (Figure 9). To repair this type of problem, remove soil away from the side of the sprinkler, straighten the sprinkler, and then replace and pack the soil around the sprinkler body.

It is also important to maintain the area surrounding a sprinkler to prevent obstruction of the spray. Turfgrass can grow over pop-up sprinklers making it impossible for the sprinklers to pop-up. Shrubs and overhanging tree branches may also need to be pruned back far enough to keep the sprinkler from being obstructed. Over time, sprinklers can be pushed further into the ground, causing the spray of the sprinkler to not reach surrounding areas.

Troubleshooting Bad Sprinkler Valves

Rain Bird Undercut NozzleThank you for visiting the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to educate our website visitors about news, tips and advice concerning sprinkler irrigation here in Central Florida and the Orlando area. Today we would like to explore a bit about troubleshooting bad sprinkler valves.

When troubleshooting an irrigation system it is important to know the various bad valve symptoms which can cause sprinkler problems. A valve that is not working properly could have various effects from various components which can malfunction. Sometimes a bad valve can be a broken sprinkler head or household water pressure problems.

Leaks around the valve are a rather obvious symptom of a bad sprinkler valve, and these leaks can actually be caused by a variety of issues. Getting to the root of the problem is the first step to diagnosing what is wrong. Find out where the water is leaking from such as around the solenoid, the anti-siphon part of the valve or perhaps around the housing of the valve itself.

If the sprinkler heads seem to get minimal amounts of water and the valve is clear, a bad valve could be the issue. Sprinkler pressure problems could be caused by the sprinkler valve not allowing enough flow through the valve.

Make sure the valve is turned on all the way first. Next, check to see if only one valve is affected or if all the valves have the same problem. If all but one valve is working properly then it is likely that all of the valves are getting sufficient water and it is just the one valve that needs fixing. If all of the sprinkler valves are not getting enough or any water then the problem is most likely not the valves. The source of the problem can be at the main sprinkler shut off or at the pressure vacuum breaker.

If the sprinkler valve will not turn on with the timer it can be a bad valve symptom but it can also be just a wiring problem. Try turning the sprinkler valve on manually to isolate an electrical issue.

When there is standing water or leaking water at the sprinkler furthest from the sprinkler valves it could be the sprinkler head, but it could also be that the corresponding valve. Standing water is a sign that the valve is not shutting off completely. If this is a new problem check for debris in the valve that can be causing it to stay open. If cleaning doesn’t solve the problem it could be that the valve is broken and once again you must decide to replace or repair it. If the problem is not new it could be that the valve was installed backwards. Check the valve to ensure that the direction of flow is pointing the right way.

Importance of Proper Sprinkler Height

sprinklersWelcome to the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to inform our online readers about sprinkler irrigation here in Orlando and the Central Florida area. Today we would like to give our website visitors some tips and advice concerning the importance of proper sprinkler height in an irrigation system.

Incorrect sprinkler head height is one of the most common problems leading to brown spots and poor growth. Heads installed at incorrect heights can also lead to damage to the sprinkler system.

When sprinkler heads are installed too deeply into the ground, they are unable to rise above the level of the ground, grass or turf, thus preventing water spraying properly. In turn, flooding around the sprinkler heads and coverage gaps could become a problem. Retractable sprinkler heads can accumulate dirt and debris which causes retraction problems and mechanism failures.

Alternately, when sprinkler heads are placed too high, there is a concern of tripping over them or even landscaping equipment such as lawnmowers or weed-whackers becoming damaged and causing damage to the irrigation system. The easiest way to correct this is to dig out around the head, disconnect it, and reconnect it using funny pipe or a swing joint, which can be positioned to exactly the right height.

Natural growth of surrounding plants can cause incorrect sprinkler height and may need adjustment as the plant grows. Sprinkler heads watering ground cover plants could also need adjustment.

Ground levels can raise and lower over time, therefore causing sprinkler heads to be too high or low. If sprinkler heads are left at too low of a height, erosion can wear away the dirt in around the sprinkler head and flooding may occur. All sprinkler systems should be checked periodically to verify that the heads are still at the correct level. Proper sprinkler height is important for a healthy lawn, to avoid injury and flooding, and even to prevent damage to your lawn and landscaping equipment.

Common Irrigation System Solutions

useful tipsThank you for visiting the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to educate our website visitors about news, tips and advice concerning sprinkler irrigation here in Central Florida and the Orlando area. Today we would like to talk about some common sprinkler irrigation system problems and their solutions.

No two landscapes are alike, and there are multiple efficient, hassle-free options for most sprinkler irrigation issues that arise. With diverse, durable and precise irrigation components, homeowners and business owners with irrigation systems can rest assured that all bases are covered as far as problems they face.

Watering slopes and hills can be an issue for most sprinkler irrigation systems. Water can puddle or pool around sprinklers installed at the bottom of slopes or hills, causing soggy areas, which can kill grass or encourage fungus to grow. Special rotors with check valves can stop the problem of low head drainage and eliminate puddling. Another solution is to use nozzles that spread water at a lower rate, allowing sufficient soak-in time to prevent run-off.

Sometimes different plant types can pose an issue. Shrubs, trees, flowers and grass all need different amounts of water. Delivering the same amount of water to every plant can cause the loss of plant life or you may simply be wasting water on plants that don’t need that much. Low-volume drip irrigation allows you to customize your water delivery to each plant’s individual watering needs. Designing a system with multiple independent zones allows you to schedule watering according to each area’s unique watering needs.

It is often difficult to get even coverage in hard to reach areas such as corners, strips or oddly-shaped patches of grass. Sprays installed with variable arc nozzles deliver precise and even coverage in almost any shape of lawn areas.

Smaller yards can be difficult to water, and sprinklers often water the sidewalks, driveways or against the home or garage. Low-volume nozzles water areas just a few feet square, resulting in optimum distribution control and uniformity. This eliminates overwatering and wasteful water run-off.

Overwatering and underwatering results for various reasons such as shade or watering needs of different areas of the lawn. Irrigation controllers can solve this problem by setting different zones for different amounts of time. Also, low-volume drip irrigation allows the customization of precise water delivery to individual plants or groups of plants, based on specific watering needs and exposure to the sun.

If sprinklers turn on during rainy weather, a rain sensor could be the solution to that problem. A rain sensor automatically monitors weather conditions and efficiently signals the controller to turn the system off when it rains, saving water and saving you money.

Water pressure issues are a common problem in sprinkler irrigation systems. High pressure can cause misting, which in turn is not delivered to the lawn properly. High water pressure can be controlled at the valve with a valve pressure regulator system. Alternately, anti-siphon drip control zone kits can be utilized for low-volume drip systems.

Regulating Water Usage

sprinkler irrigation system
Welcome to the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to inform our online readers about sprinkler irrigation here in Orlando and the Central Florida area. Today we would like to give our website visitors some tips and advice concerning how to better regulate a sprinkler system’s water usage.

Saving water is just like saving money. As your landscaping matures and evolves, its watering needs change. Using your water efficiently is key to lowering your water bill, which translates directly to money in your pocket.

Avoid overspray on sidewalks and walkways to prevent too much water usage and lower the water bill. In certain cases, residential customers can use nearby water sources such as a lake for irrigation purposes to save water. Saving money is always a plus and lake water can be a solution that saves our customers a ton of cash.

If you water the lawn with a hose then it is time to have your sprinkler system evaluated and possibly updated. Plants need water to survive and accurate watering is essential to a healthy, green lawn.

Use water restricting parts so the lawn gets just enough water. There is no need to waste water when it isn’t necessary. A great idea to conserve water is by using rain barrels or a nearby lake. Saving water means saving money on your water bill.

A problem with the irrigation system controller could prompt need for repair. Timer conflicts and impaired rain sensors could be altering watering times and therefore cause dead foliage. A properly designed sprinkler system in excellent condition can give you a healthy lawn.

Low water pressure could prevent proper water coverage for your lawn. If your sprinkler system needs repair, your lawn may have dry yellow or brown spots. When the water isn’t sprayed to the optimum capacity of your irrigation system, there could be dead, dry spots in the lawn.

If your irrigation system is working properly, you will not have to rely much on Mother Nature. Different amounts of water are required depending on plants, grass and type of soil. Only water when needed. Schedule watering periodically or use a rain sensor to adjust when watering times proceed. Early morning and evening are the best times to water.

Exploring Irrigation Controllers

Rain Bird ESP with Rain Sensor

A Rain Bird ESP controller and a Rain Bird WR2 rain sensor


Thank you for visiting the Hessenauer Sprinkler Repair and Irrigation blog and website. We like to inform our online readers about news, tips and advice concerning sprinkler irrigation here in Central Florida and the Orlando area. Today we would like to explore a little more about how irrigation controllers work.

Due to the nature of rainfall all over the world, there are inevitably going to be times that artificially watering the turf and landscape becomes necessary. An ideal irrigation system for turf and landscaping should utilize a minimum number of valves, supply lines and sprinklers. Generally, the valves are turned on and off by a reliable electronic irrigation controller.

These irrigation controllers can be programmed to carry out a wide variety of watering schedules. The goal is to uniformly distribute the optimum amount of water over a given area. The zones, placements and flow rates for each sprinkler is pre-determined upon the design and installation of the irrigation system.

Optimum flow rates which are provided for each sprinkler should fall within about a quarter gallon per minute, or GPM. The amount of water supplied by each sprinkler is largely determined by the size and configuration of its nozzle, although variations result from fluctuations in water pressure that cannot be fully negated with regulators.

Residential and commercial irrigation systems typically include one or more solenoid operated valves that are turned on or off by an electronic irrigation controller. The valves administer water to various underground lines usually made of PVC pipe which typically have several sprinklers connected to risers coupled to the branch lines at spaced intervals. The combination of a solenoid and associated sprinklers is generally referred to as a zone or station. A modern electronic irrigation controller typically includes a microprocessor that executes one or more watering programs.

The controller usually has an LCD display to facilitate the programming by the user. In case of a power failure, the irrigation controller will revert to a default watering program. The microprocessor controls the solenoid devices through electric switching devices, opening and closing the valves appropriately. Each station is then controlled by a corresponding station module which comprises a plastic housing that encloses and supports a station module circuit, as well as wire connection terminals for connecting wires to a plurality of solenoid actuated valves.

Expandable irrigation controllers have gained popularity because they are a hands-free solution to proper watering for the lawn. The advantage of an irrigation controller with a modular expandable configuration is that the controller need only be equipped with the minimum number of station modules that can control the total number of stations needed. Thus, for example, an irrigation system may have only three zones, requiring only a single station module, while another may have twelve stations which might require four station modules.

One type of irrigation controller that does not require a dedicated field valve line to each station is the “decoder” system. These are available in either two wire or three wire versions. In a two-wire decoder system one or two way communication between the microprocessor and the valves is achieved by encoding signals and transmitting them over the same two wires that carry the power to the valve solenoids. The valves are connected in parallel to the two wires through decoder circuits that are used to identify commands uniquely intended for that station.
