If you have a 3/4 in. copper or cpvc pipe bring water into the water heater and 3/4 in. leaving the water heater and your cold water pressure is strong you should have good hot water heater pressure. If you have older galvanized pipe or any 1/2 in. pipe entering or leaving the water heater you will not be able to get great hot water Low hot water pressureClogged valves can cause low pressure in the shower. Whenever you have low water pressure in a single room, such as the bathroom, you need a simple diagnostic strategy to pinpoint the problem because there isn't always a simple explanation.

In some cases, you'll be able to narrow the problem to a single faucet or fixture, but in others, you may end up having to inspect the hot water heater. If you have a leak, it probably won't be hard to find. Pinpointing the Problem If only one fixture or faucet in the bathroom has low pressure, you shouldn't have to look farther than the fixture itself for the problem. There is probably a blockage in the valve or aerator or a misadjustment of a temperature limiter. If more than one fixture is affected, you may also find low pressure in other rooms in the house because the cause is likely a partially closed valve or a blockage in a main supply pipe. If there's a leak, it can affect a single fixture as easily as it can affect many. Leaks usually make themselves known by pooling water or soaked drywall. Loss of Pressure at a Single Fixture When the pressure at a single fixture is lower than expected, it could be because mineral deposits have blocked the valve or the aerator. It's easy to check the aerator -- just unscrew it and look inside it.

If you see white deposits, either flush them out with water or soak the aerator in white vinegar to dissolve them. White vinegar is also effective for dissolving deposits from the valve mechanism. Sometimes, the pressure is low because the temperature limiter isn't adjusted properly. The limiter is a plastic washer that you can adjust by hand after removing the faucet handle. Loss of Pressure in the Entire Bathroom Low water pressure in the entire bathroom signifies a blockage or leak in the main pipe that supplies water to it, and the problem may also affect fixtures in other rooms. A blockage may be something as simple as valve that someone partially closed -- perhaps to make a repair -- and forget to reopen. Blockages also happen around old water heaters as rust and minerals clog the hot water output. You can usually flush these after turning off the heater and allowing the water to cool. Air in the pipes can also cause a blockage. You can often purge air by opening all the faucets in the house at once while you flush the toilets at the same time.
