Most people don’t think about water pressure. We all like the fell of a lot of pressure in the shower, however this pressure is also constantly pressing against the interior walls of the pipes in your plumbing system. This pressure is also causing pressure on the plumbing joints. As mentioned earlier, the joints are one of the most common causes of these leaks. If you hear your plumbing when you flush your toilet, or when you turn your water on or off, you may need to have your water pressure checked and regulated.
