Where to Find Your Main Water Shut-Off Valve (and Why You Need to Know BEFORE…
High Water Pressure Is Like High Blood Pressure in Your Body
High blood pressure quietly damages your arteries and organs for years before you ever feel a symptom. High water pressure does the exact same thing to your home’s plumbing — and the “heart attack” is usually a burst pipe, a blown water heater, or a $20,000+ flood.
Most homeowners in The Triangle and Upstate SC think a suddenly stronger shower is a good thing. It’s not. It’s usually the first sign that your pressure reducing valve (PRV) has failed or that the city just turned up the street pressure (very common in our fast-growing area).
Why High Water Pressure Is Dangerous
- Shortens the life of every faucet (Kohler, Moen, Delta), toilet (American Standard, Kohler), water heater (State, Rheem, A.O. Smith), washing machine, and dishwasher
- Greatly increases risk of pinhole leaks, burst pipes, and water-heater T&P valve failures
- Wastes water and raises your bill
- Can actually void manufacturer warranties
Manufacturer-recommended safe range: 45–60 PSI Anything over 80 PSI requires a properly functioning pressure reducing valve by NC & SC code
Warning Signs Every Homeowner in Raleigh-Durham & Greenville-Spartanburg Should Watch For
- Suddenly stronger flow from ALL faucets/showers at once
- Banging or hammering pipes (water hammer)
- Leaking faucets or running toilets that won’t stop
- Dripping water heater relief valve
- Sudden drop in pressure everywhere in the house (failed PRV)
Quick diagnostic tip: If low pressure is only at one fixture → problem is at that fixture. If pressure is high or low at every fixture in the house → the issue is almost always your main pressure reducing valve or municipal supply.
How Long Does a PRV Last?
10–15 years on average. Some reach 20. Like any mechanical device, they eventually fail — and when they do, pressure either skyrockets or drops dramatically.
