(253) 378-0055Low and High Pressure Are Different Problems With Different Causes
Low water pressure affecting the whole home is most commonly caused by mineral scale buildup narrowing older galvanized supply pipes, a failing or improperly set pressure-reducing valve (PRV), or a partially closed main shutoff valve. If only one fixture has low pressure, the cause is usually local — a clogged aerator or a fixture-specific supply line issue.
High water pressure — often signaled by banging pipes (water hammer) when a faucet shuts off, or premature fixture and appliance wear — typically means your home's pressure-reducing valve has failed or was never installed. Washington State code generally caps residential water pressure at 80 PSI; many Kent properties on higher municipal pressure zones require a PRV to stay within this range.

Diagnose First, Then Fix the Actual Cause

We test water pressure at multiple points in your home and at the main supply to determine whether the issue is home-wide or fixture-specific. For low pressure from scale buildup, this often points toward a larger repiping conversation. For a failing PRV, we replace it and set it to the correct pressure for your home.
For high pressure and water hammer, we install or replace the pressure-reducing valve and can add water hammer arrestors at problem fixtures to eliminate the banging sound and protect your plumbing system long-term.

Frequently Asked Questions
Most residential systems operate well between 40 and 60 PSI. Washington State code generally requires pressure-reducing valves to keep pressure below 80 PSI.
This is called water hammer, usually caused by high water pressure or a failing pressure-reducing valve. It can be resolved with a PRV repair and water hammer arrestors.
Not always — it can also stem from municipal supply issues. We test pressure at your main line to determine whether the cause is inside your home or upstream.
Yes. Mineral scale buildup inside aging galvanized pipes narrows the interior diameter over time, reducing flow and pressure throughout the home.
A standard PRV replacement typically takes one to two hours.
