About this service

Typical cost
$200 - $1,800

Professional water pressure regulation in Seattle relies on a Pressure Reducing Valve (PRV) to lower high municipal water pressure to a safe residential range of 40 to 60 PSI. High water pressure damages appliances and causes leaks. Standard PRV replacements cost between $200 and $700, but digging up and replacing a buried outdoor PRV can cost $1,200 to $1,800.

Primary Cause of Failure

  • •Wear and tear of the internal rubber diaphragm and spring over its 5-to-10-year lifespan

If neglected

High municipal water pressure enters the home's plumbing, causing silent toilet leaks, damaging appliances, and causing pipe ruptures behind walls.

Probability of a DIY fix for Water Pressure Regulation and Adjustment?

Low. Working on pressurized main service lines carries immediate risks of stripping old pipes and causing sudden indoor flooding.

Insurance coverage

Insurance does not cover PRV replacement, but it will cover the resulting water damage from a burst pipe.
