Sprinkler Valve Leaks: Common Causes and How to Fix It

One of the most common reasons that people call for sprinkler repair is a sprinkler valve leak. Sprinkler valve leaks are important to address because even the smallest leak will waste more water – and more money – every day that the leak goes unattended.

When there doesn’t seem to be any visible damage to the sprinkler head, then damage to the valve seal is likely the culprit. However, it’s also possible that it could be one of the other common causes for a sprinkler valve leak. Here are the most common reasons for a sprinkler valve leaking and how our team at Andy’s Sprinkler, Drainage & Lighting would fix the issue:

Why is My Sprinkler Valve Leaking?

Sprinkler valve leaks are generally due to one of two reasons:

1. Low Head Drainage

After each run of your sprinkler system, if there is excess water that is still draining from the pipes after the water is switched off and the leaks are happening directly after running the sprinkler system and do not occur all the time, then the cause is “low head drainage”.

It’s important to note, however, that this drainage issue should stop after a short time. If it doesn’t, then you likely have an issue with your irrigation system that needs to be addressed immediately.

2. Rubber Diaphragm Seal Break

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 yard. If this happens to you, it’s very important that you contact an expert as soon as possible so that any potential water damage will be minimized. A broken or aging sprinkler valve diaphragm seal only gets worse over time.
