The signs are banging pipes when water shuts off, faucets that spray forcefully, repeat leaks in different locations, a water heater relief valve that weeps, and appliance supply hoses failing. The definitive answer takes two minutes: put a gauge on a hose bib and read the pressure.

Measure It First

An inexpensive pressure gauge threads onto an outside hose bib. Read it with no water running. That single measurement tells you more than any list of symptoms — and it is worth checking at night as well, since municipal pressure typically rises overnight when demand drops. A house that reads acceptable at 6 p.m. can be well over the safe range at 3 a.m., stressing everything while you sleep.

The Symptoms

  • Water hammer. Banging or knocking in the walls when a faucet closes or the washing machine or dishwasher shuts a valve.
  • Forceful, hard-to-control faucets and showers that feel harsh.
  • Repeat leaks in different places. This is the telling one. Individual leaks look unrelated; excess pressure is the common cause.
  • A water heater T&P valve that weeps or discharges — often blamed on the valve when the actual problem is system pressure.
  • Short-lived fixture seals, cartridges, and washers.
  • Appliance supply hoses failing, which is how kitchens and laundry rooms flood.
  • Running toilets from fill valves that cannot seal against the pressure.

You May Already Have One That Failed

PRVs wear out — typically after a number of years, and hard water accelerates it. A failed valve either sticks open (no reduction at all) or closes down too far (low pressure throughout the house). If your home has one and pressure reads high, replacement rather than installation is likely the answer.

Why This Is Worth Doing

A PRV is inexpensive relative to the damage excess pressure causes over years. It is the single highest-return preventative item in most Albuquerque homes, and it is the thing homeowners are least likely to have checked.
