In Escondido's oldest homes, the plumbing has been taking full street pressure for decades, either because the regulator quit years ago or because one was never installed. The noise is usually what finally gets noticed, the banging when the washer stops, the knock when a faucet closes fast. The noise is real, but the bigger cost is the wear you can't hear.
Pressure out of range wears on the whole system. It stresses century old joints, wears faucets and fixtures early, strains supply lines, and shortens appliance lives across the board, and the water heater takes the most, since a tank under constant high pressure wears out early. In Escondido's older homes, where the plumbing already has plenty of years on it, high pressure speeds up that wear. The PRV handles it at the source, one device holding the entire system in the healthy range, and whether it's working, failed, or never installed, the symptoms look the same until somebody measures.
Measuring is the visit. A licensed contractor puts a gauge on the system, reads what the street has been delivering, checks the regulator, and explains what's there, what it's doing, and what the options are. Homes without a regulator get the straight version of what adding one protects. The pressure has been wearing on your plumbing for generations. A gauge test shows where it stands.
