When you turn on the water for an appliance, the last thing you want is for the appliance to not have enough water pressure. This can lead to you not having enough water to take a shower. There are several issues that can lead to low water pressure, but there are also several things you can do about it. 

Too Many Fixtures

The more fixtures you have in your home, the more that this will affect your water pressure. However, if there is no way to reduce the number of fixtures in your home, you may still be able to solve the problem with a water pressure booster installed at the water meter. 

Improperly Set Water Spigot

The first step in fixing your water is to check the water pressure with an outdoor water spigot. In some cases, you might simply need to turn the water pressure handle to solve the problem. While it might sound obvious, a lot of homeowners forget this step. If your house uses city water, ask for your water pressure to be checked. You'll ideally want your water pressure to be at 45 PSI or higher. In some cases, cities have delivered water pressure that was below 40 PSI.

When increasing your water pressure, it's important to track how much you have increased it. When water pressure is raised too much, it can wear out your washers and may also cause damage to your plumbing fixtures. 

Plumbing Issues

After checking the water pressure, if you don't find any problems, the issue might instead lie with the plumbing. When your pipes have clogs, this can reduce your water pressure. In other cases, you might simply have pipes that are too small and should be replaced.

A Bad Pressure Reducing Valve

In some cases, you might have a pressure reducing valve that is mounted to your main. Under these circumstances, the valve can go bad and will reduce the amount of water pressure in your home. Replacing the valve will correct the problem. 

A Bad Fixture

Make sure that all of your fixtures have a water pressure problem and not just one. If only one fixture has a water pressure problem, you may need to simply fix the fixture. If you still can't figure out what is wrong with your water pressure, you might need to hire a residential plumber. He or she can troubleshoot the problem and come up with a remedy.
