Why Does My Sprinkler Valve Leak?

A leaking sprinkler valve is one of the most common reasons customers call for sprinkler repair. Left unchecked, even the tiniest leak wastes water and costs money.

If there seems to be no damage on the sprinkler head, the valve seal is likely the reason.

The most common causes of sprinkler valve leakage are listed below.

1. Low head drainage

There is low head drainage after each run of your sprinkler. It means that extra water is still draining from the pipes after the water is turned off. If the leaks occur shortly after turning on the sprinkler system and are not frequent, regular drainage is most likely causing the issue. It’s important to note that the discharge should stop after a short period. If it doesn’t, you most likely have a leak that needs to be addressed.

2. Valve seal break

When the valve box leaks, the likely reason is that the rubber parts have worn out. When the diaphragm seal fails, or dirt prevents the valve from shutting, water seeps freely through the system. When this happens, unneeded water flows continuously, potentially causing other problems to your lawn. If this occurs, contact a professional for repair and to avoid further damage.

What Are the Signs of Sprinkler Valve Leak?

Sprinkler leaks pose more than just a threat of wasted water and high utility bills. If a leak is substantial or untreated, it can cause further issues. Sinkholes and subsurface cavities can form, causing damage to property and utility lines. In addition, uneven watering caused by a malfunctioning sprinkler system can damage plants and ruin portions of your lawn.

Knowing the environmental and data-driven symptoms of a leak can help you prevent damage and save money on repairs and water bills.

Here are the signs of a sprinkler valve leak on your lawn.

1. An increase in your water bill

You may have a sprinkler valve leak if you haven’t been using considerably more water, yet you receive a significantly higher-than-normal bill after you start using your sprinkler system. It is also possible that there could be a leak somewhere in the house. Install a dedicated sprinkler meter to determine whether the problem is indoors or outdoors.

2. A pool of water around the sprinkler head

While your landscape may appear dry due to uneven watering, leak sites can be identified by puddles near the sprinkler head or in other areas of the yard that indicate excessive water flow.

3. Visible damage

Look for cracked pipes, broken solenoid valves, and damaged sprinkler heads.

4. Low pressure

Like other types of pipe leaks, pressure can reveal what is going on inside a system. When it’s too low, it could indicate a problem with the water supply, indicating a leak. Sprinkler heads frequently spew very little water or don’t lift at all in this situation.

5. Dry lawn

If your yard doesn’t appear to have been watered, your sprinkler system may be malfunctioning. You might also note that one area is dry, but another area is green. This could assist you in locating the leaking sprinkler valve.
