How to Prevent Damage by Installing a Pressure Regulator at the Meter

Prevent damage to your plumbing and waste due to excess pressure in you irrigation system by installing a water pressure regulator at the water meter. Greg shows you how, step by step.

Water company street pressure is often much higher than the recommended 80 psi for landscape and household plumbing. This puts the pipes under higher stress than necessary and more likely to leak and break over time. Sprinkler systems with too high a pressure will mist excessively, often wasting 50% of the water applied.

This video shows a southern California water meter installation. Meter location and configuration will vary by region, as dictated by local codes and weather (in Northern climates the meters are often in the house where they cannot freeze); however, the principle remains the same: protect ALL the pipe that is on the homeowner's side of the meter, not just what goes directly into the building.

Time to complete One to two hours ( Your water will be shut off during the entire job. Be sure to allow extra time for troubleshooting - don't start shortly before dark.)
