Water pressure problems in Lakewood homes usually come from one of four things: corroded galvanized pipe, a failing pressure-reducing valve, a partly closed or failing shutoff, or a clogged fixture or aerator. If only one faucet is weak, start there. If the whole house is weak, or pressure is so high that pipes bang and relief valves drip, the cause is at the main line or regulator.
Whole house or one fixture?
If one faucet or shower is weak, unscrew and clean its aerator or showerhead, and check that the fixture's shutoff valves are fully open. If hot water is weak everywhere but cold is fine, the water heater's connections or hot-side piping may be restricted. If everything is weak, look at the main shutoff, the pressure regulator and the supply piping. Our low water pressure troubleshooting guide walks through these checks.

Galvanized pipe and pressure
Many Lakewood homes built between 1950 and 1953 were plumbed with galvanized steel. As it corrodes inside, the opening narrows and flow drops, especially on hot water and at the far end of the house. If you have galvanized pipe and pressure has been slowly getting worse, repiping may be the lasting fix.

Call (708) 350-9399Pressure that is too high
High pressure is as much of a problem as low. Signs include banging pipes when valves close, toilets that run, a water heater relief valve that drips, and appliance hoses that fail early. A failing pressure-reducing valve (PRV) is a common cause. A provider can measure static pressure at a hose bib with a gauge and test or replace the PRV.
Utility-side causes
Sometimes the cause is outside your home: utility main work, a hydrant flush, or a problem at the meter. If neighbors notice the same drop at the same time, check with your provider. That is the City of Lakewood water utility west of the San Gabriel River, or Golden State Water Company east of it (ZIP 90715), per the City of Lakewood water services page.
What to have ready when you call
Note whether the problem is hot, cold or both, whether it affects one fixture or the whole house, when it started, and whether you know your pipe material. A photo of the pipes at your water heater and main shutoff helps the provider understand the system before the visit.
