QUESTION: How do I fix high water pressure that makes my toilet constantly run?
High water pressure is a potentially serious plumbing problem. It can strain the components of your fixtures so that they start to leak. It can also cause your pipes to vibrate against each other or the wall, which can damage the pipes or even cause them to burst inside your walls.
Unless you live in a rural area and use well water, your water probably comes from your local water district or public utility. The high water pressure could be caused by a problem on the provider’s end, so the best place to start is by contacting them. Your water provider may send someone to check the pressure of the water entering your home. If it does show to be too high, they may install a pressure-reducing valve for you. Depending on where you live, you may be responsible for the cost and installation of the pressure-reducing valve. In this case, it is best to contact a licensed plumber to verify that you have high water pressure and to handle the valve installation for you.
