The water pressure is low in my house and slowly getting worse. What can be done to increase it?
What most people call low pressure is actually low volume. Volume is the number of gallons per minute flowing through your water lines. The water pressure (which is measured in psi or pounds per square inch) in the water main serving your residence will be the pressure in your line. The volume can vary greatly from house to house on a given street due to a number of factors. If you have an old galvanized houseline or galvanized interior pipes, over time these corrode and will reduce the interior diameter of the pipe to as small as a pin hole. To fix the problem requires replacing the old galvanized interior pipes with copper or plastic pipes. If that does not solve the problem, than you have to replace the old houseline with a new K copper houseline.
