If you have low water pressure in your home, then this may make it extremely difficult to take showers and complete other everyday tasks. For this reason, you may want to think about boosting the pressure. While a plumber may be needed for this, there are a few easy things that you can do before calling in the professionals.
1. Replace the Water Pressure Regulator
Some homes have a small device installed just after the water main to help keep water pressure at an optimal level. This device is called a water pressure regulator and it typically reduces pressure when it is too high for residential use. Unfortunately, this regulator can fail over time and this can create a situation where water drops substantially. The drop may be due to the way that the spring-loaded diaphragm falls due to age or internal mineral accumulations may clog the unit.
You can replace the pressure regulator on your own, but first try to adjust the device to make sure that it is set correctly. Adjustments can be made by twisting the top screw to the left. This opens up the valve a small amount which allows for more substantial water flow and increased pressure. You can watch the small gauge on the top of the device as you make your adjustments.
Start by increasing pressure by 10 psi and then check to see if pressure increases at the faucet. If it does not, then purchase a new regulator at your local home store and replace it. Make sure to turn the water off at the main when making the repair and also use plumbing dope or tape around the threads when securing the device.
2. Make Sure All Valves Are Open
Sometimes a main or secondary water valve can accidentally close. This may be due to the accidental nudging of the valve or you simply may not have opened up the valve all the way after a repair was made. This can substantially reduce your water pressure depending on the location of the valve. So, you want to move throughout your basement making sure that all water valves are fully open.
Since most water valves are controlled with ball valves, you can simply turn each valve handle so it is completely parallel to the water pipe. If you feel some resistance, do not force the handle. Contact local plumbing services. The valve may be stuck and in need of a replacement. If you are able to adjust the handles, then check for water pressure afterward to see if it has returned.
