A technician was assisting a water softener installer who was replacing a fairly new softener because the first one had ruptured and filled the pipes with little zeolite beads.
The installer didn’t seem too worried about why the first one failed, but the assistant did a little investigating. A water pressure test gave a reading of more than 110 lbs. psi. The culprit was the 20-year-old pressure-reducing valve. After a new valve was installed, the pressure went down to about 75 lbs. Pressure-reducing valves are usually found near the main water shutoff valve, but not all homes have them. It depends on your municipality.
High water pressure can harm pipes, connections, and appliances. It also creates water hammer and waste massive amounts of water. Checking for high water pressure is an often overlooked maintenance item, and one that’s easy enough to perform. A new pressure-reducing valve and a simple pressure gauge like this one that hooks up to a spigot or laundry tub faucet are both available at home centers.
