No matter where it happens, ineffective hot water pressure can upset your daily routine and even your entire lifestyle. Poor hot water pressure in the laundry room hinders the washer's ability to fill up quickly and clean clothes thoroughly. In the shower, poor hot water pressure can make a hot shower frustrating, time-consuming and ineffective. But there are some easy ways to fix the hot water pressure if you know what is causing the problem.

Clean the plumbing fixtures. If you have water pressure problems only at one location, it may be due to a single fixture. In some cases, mineral deposits from the water build up over time, and a shower head or sink faucet with poor water pressure may just need a good cleaning. Find a good lime remover available in most grocery stores. Take the fixture apart and soak the pieces in a container of lime cleaner for at least one hour. Reassemble the fixture and check the water pressure again.

Replace the fixture if cleaning the fixture does not help considerably. The hot water pressure can be easily affected if a faucet's internal mechanism wears out or breaks down. Often, simply replacing a faucet or shower head with a new one will solve the water pressure entirely.

Check for plumbing leaks directly beneath the fixtures and follow the lines as far as possible into the basement or walls. Even a slight break in a water line, which does not create a noticeable plumbing leak, can greatly affect the hot water pressure at one location or throughout the house. If the air pressure is disturbed, the water pressure will have difficulty building momentum. If you do find a leak or a break in a pipe, solder a metal pipe closed using a soldering iron and solder. A break or crack in a PVC pipe will need to be cut out and replaced with a new section of PVC and plumber's caulking.

Water pressure problems may stem from the boiler or hot water heater. (ãà çîâà ÿ êîòåëüíà ÿ image by YURY MARYUNIN from

Flush out the boiler or hot water heater, as this can sometimes help a water pressure problem and reduce the level minerals and sediments that may clog the faucets and shower heads. Attach a hose to the drain in the bottom of the tank and drain the hose into a large bucket or outdoors. Open the pressure relief valve and then open the boiler drain. Let it run until the water runs clear and traces of rust or sediment no longer appear.
