Why Is My Irrigation Pressure so Low?

One of the most common issues with irrigation and sprinkler systems is low water pressure. Sometimes low pressure can be repaired quickly with a few DIY tricks and tips, but sometimes you need a professional. Here is a quick checklist you can run down to see what category your low-pressure problem falls into. If you run into any issues, don’t hesitate to call General Plumbing for assistance.

Broken Water Line

One of the first things we consider when there is low irrigation pressure is a broken line. Has anyone dug in your yard recently? Has anyone placed anything beside a sprinkler head or installed a fence nearby? These projects are the common causes of a ruptured line.

Backflow Preventer Valve

Each home has a backflow preventer which has two pipes running horizontally and vertically. The valves control the flow of water. If it is partly shut, the water may not flow at the correct pressure. Check to make sure your backflow preventer valve is correct prior to calling your plumbing professionals.

Line Clogs

If the low pressure is occurring at just one sprinkler head, you may have a dirt or grass clog in the line. Check the area around your sprinkler head to ensure there are no long grasses or weeds impeding the flow of the sprinkler head. With a small hole or crack, dirt can easily find its way in.

City Water Supply Issues

When the demand for water is particularly high, a city’s water system may have a hard time keeping up. Often you can give a call to your municipal water company to inquire about the water pressure. It may be an issue with the system at large rather than your irrigation piping.
