High Water Pressure at the Hose Bib
On a recent home inspection in Las Vegas, we tested the water pressure at an outdoor hose bib and got a reading of 85 PSI. Most homes do best somewhere between 40 and 80 PSI, so this one was running on the high side.
What This Means For You
Water pressure is how hard the water pushes through your pipes. A little extra feels nice in the shower, but every pipe, valve and appliance in the home has to hold back that force all day long, even when nothing is turned on.
Most homes have a pressure regulator where the main water line comes in, often near the front hose bib. Its job is to bring the city's water pressure down to a safe level. When the regulator is set too high or isn't working right, that extra pressure goes straight into the home's plumbing.
Why It Matters
High water pressure rarely causes a problem overnight. It just wears things out faster. Over time it can lead to:
- Dripping faucets and toilets that keep running
- Worn-out washers, valves and supply lines
- Leaks at the water heater, dishwasher, washing machine or fridge connections
- Banging sounds in the pipes when a faucet shuts off
Las Vegas water is also hard, so fixtures here already take a beating from mineral buildup. Extra pressure on top of that shortens their life even more.
What We Typically Recommend
We recommend having the pressure regulator adjusted so the water pressure falls between 40 and 80 PSI. If the home doesn't have a regulator, or the one it has isn't holding pressure, a licensed plumber can repair or replace it.
You can also check your own home's water pressure with an inexpensive gauge from the hardware store. Screw it onto an outdoor hose bib, open the valve and read the number.
Main Takeaway for Las Vegas Home Buyers
Water pressure is easy to miss because everything seems to work fine. But anything over 80 PSI puts constant strain on your plumbing and appliances. A quick adjustment now can help prevent leaks and early repairs down the road.
A professional home inspection includes a water pressure check, so you'll know where your home stands before small issues turn into bigger ones.
