Rx for Sprinkler Pressure Problems

We get a lot of calls from customers who think there’s something wrong with our pressure irrigation (PI) system because their sprinklers aren’t scattering water as far as they used to.

While there are times of high demand when the pressure is lower in our system, in the vast majority of cases the problem is somewhere past the hookup to the customer’s system. This is the customer’s responsibility, and not something that we can fix.

Check the filter first

If your system isn’t watering as vigorously as it used to, nine times out of ten the problem is in the filter. Because the PI water is not treated to the same degree as drinking water, there might be sand or other particles that clog the filter and reduce the flow until the filter is cleaned.

To clean the filter:

  1. Turn off the stop and waste.
  2. Remove the filter canister from the system.
  3. There are two types of filters: one with a cylinder and one with discs. Either remove the cylinder or loosen the nut that compresses the discs.
  4. Rinse any debris off the cylinder or disc
  5. Reassemble and replace the canister into the system.
  6. Turn the stop and waste on.

It’s a good idea to clean the filter about once a month during irrigation season. If you don’t want to do this yourself, ask your lawn maintenance company or landscape professional to do it for you.

Other steps to try

If just one sprinkler head is under performing, remove just that head and clean its individual filter.

If your system hasn’t been putting out enough water all season, check that the stop and waste valve is completely open.

You can also adjust your timer to water at a different time of day. When there’s less demand on the system, your water pressure will be higher.

Please try these steps before calling WaterPro. Our crews are very busy during the summer months, so it can take some time to respond to a call that could be resolved easily by the customer.

If the demands on our crews increase, we may have to begin charging when customers call us to resolve a situation that is the customer’s responsibility.
