Why does my sprinkler valve keep leaking?
The most common reason leaks occur is that the rubber parts in the valve box have worn out. Water seeps freely through the system when the diaphragm seal breaks or debris is obstructing the valve from closing. This means unnecessary water is flowing 24/7 and could be causing other issues in your landscaping.May 1, 2014

How do sprinkler systems work in buildings?
Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the air is hot enough and reaches a sprinkler head, it triggers a chain reaction.

2. Too Much Pressure on the Sprinkler System
When you have too much pressure on the sprinkler system, it can lead to a leak. This is often caused by too many heads per zone or an oversized pump running all day long.
3. Start-Up or Shut-Down Problems
If you have start-up or shut-down problems with your sprinkler system, this could lead to leaks. This usually happens when the pump doesn’t get enough water due to a blockage in pipes, insufficient pressure on the lines, and dirty filters or pump screens.
4. Broken or Damaged Valves
If you have a broken sprinkler valve, this can cause leaks. This is also true if the valves are working correctly but there’s some other problem with your system that has led to water pressure loss and makes it difficult for them to work as intended.
5. Blocked Distribution Lines
If you’re noticing leaks in your system, it could be because of a blocked distribution line. This blockage can be caused by dirt, rust or other debris that the water can’t flow through. Another thing to keep in mind is that your system may be too close to a tree or other vegetation, either of which could be the culprit.
6. Malfunctioning Sprinkler Heads
If you have a malfunctioning sprinkler head, this could cause leaks. This is especially true if the heads aren’t being cleaned monthly (as instructed) and buildup on the ports prevents them from opening to release water pressure or close properly.
7. Poorly Maintained Sprinkler System
If your sprinkler system isn’t being maintained, this could lead to leaks. This can happen due to the age of your equipment and a pressure loss in pipes that’s making it difficult for valves to work as intended or because there may be some other problem with your entire system, such as broken wires/sprinklers.
8. Poorly Drilled Pipe
If you have poorly drilled pipes and there are leaks at the sprinkler head, this is a common cause for concern. If your whole system has poor water pressure/flow as well, then it’s likely due to some other problem with pipes and valves, but if only one or two heads are leaking, chances are this is the cause.
Why does water leak through a sprinkler valve?
The most common reason why water leaks through a valve is because there is debris obstructing the valves diaphragm. Hunter sprinklers are also able to have check valves added in the field after they are installed.
Why does my sprinkler system leak water?
There are two reasons why a sprinkler will leak water when the system is supposed to be off. The most common reason is called “Low Head Drainage”. "Low Head Drainage" occurs when the lowest head on a zone allows water to drain from the lateral piping, out of the sprinkler. If it is low head drainage, residual water will stop flowing after all ...
Why does water stop flowing in my sprinkler system?
If it is low head drainage, residual water will stop flowing after all the water has left the pipe. The solution is to install check valves, such as the HCV, on sprinklers and lateral lines. The other reason may be water leaking through the zone valve (a check valve in the sprinkler will not fix this leak).
Why does my sprinkler system leak?
From time to time, the valve can leak. The most common reason is dirt in the valve, preventing the poppet from sealing.
What happens when you turn on a sprinkler?
When you turn the sprinkler or faucet on, however, the water pressure pushes the poppet up against the port, sealing the valve. When you turn the water off, the spring pulls the poppet away from the opening. This allows air to come into the valve, equalizing the pressure within the pipe.
What is a worn rubber gasket?
Worn Rubber Gasket or Poppet. The gasket or poppet, when they wear down, allows pressurized water to spray out of the valve when either the sprinkler or faucet is on. There is an important difference that is worth nothing: the valve still works.
How to attach a PVC pipe to a saw?
Start by attaching the coupler to the top of your sawed off piece of PVC pipe. Use primer and glue at the edges of the pipe as well as inside of the coupler. Then, you will want to cut off a short section of PVC pipe – 2 or 3 inches at most – and insert it into that coupler.
What is a backflow preventer?
This is a term that encompasses any device that prevents water from reentering the public water system. An anti-siphon valve is a more specific kind of backflow preventer.
Why is my poppet not sealing?
When dirt gets into the anti-siphon valve, the poppet can’t properly seal when the water gets turned on. If the poppet can’t seal, water will leak out as a result. Try using a q-tip to clean around the valve.
What is an anti-siphon valve?
The anti-siphon valve prevents water from flowing backward into the pipe. For outdoor faucets, it allows any residual water trapped in the faucet to drain. This helps to keep the pipe and faucet from getting damaged by frozen water when winter comes.
