Water pressure in Monroe ranges from 35 to 120 pounds per square inch (PSI), depending on the location. If the water main that serves you has a pressure greater than 80 PSI, you should install a pressure-reducing valve set at 80 PSI or less to protect your plumbing. If you are concerned about your water pressure or faucet flow rates, check to see if you have galvanized iron plumbing or if the pipe that connects you to the City’s water line is galvanized iron. Over time, galvanized iron pipe corrodes on the inside and the rust can cause blockages that restrict the flow of water. If you have pressure or flow problems and your plumbing and service line are copper or plastic, call Monroe Public Works at 360-794-6100.
