Water pressure that is too low makes showers weak and slow to fill, and pressure that is too high strains pipes, fixtures and appliances. We test your water pressure and fix the cause so everything runs the way it should.
Signs of a Water Pressure Problem
- Weak showers and slow-filling tubs
- Pressure that drops when another fixture runs
- Banging pipes when faucets shut off
- Leaking faucets, toilets or relief valves
- Pressure over 80 psi on a gauge test
Finding and Fixing the Cause
Low pressure can come from clogged aerators, a failing pressure regulator, corroded pipes, a partly closed valve or a hidden leak. High pressure usually means the regulator is missing or has failed.
We test the pressure, check your regulator and main valve and explain what we find. Common fixes include replacing the pressure reducing valve, adding an expansion tank or repairing the section of pipe causing the problem.
