How to Check Your Home's Water Pressure

High water pressure is a silent pipe-killer. Attaching a simple gauge to an outdoor spigot ensures your pressure stays within the safe 40-80 PSI range.

Why It Matters

Learn how to measure household water pressure with a simple gauge and identify pressure that may damage pipes and plumbing fixtures.

Before You Start

  • Obtain a screw-on water-pressure gauge.
  • Use an outdoor hose bib or another suitable threaded connection.
  • Test when water is not being used elsewhere in the house.

Step-by-Step Guide

1

Turn off faucets, showers, appliances, and irrigation systems.

2

Attach the pressure gauge securely to a hose bib.

3

Open the valve fully and read the pressure.

4

Record the result.

5

Repeat the test at another location if the reading seems unusual.

6

If pressure is consistently excessive or unusually low, investigate the pressure-reducing valve or call a plumber.

Frequently Asked Questions

Where should I attach the gauge?

The best place is an outdoor hose bib (spigot) that is as close to where the main water line enters the house as possible. You can also use the washing machine hookup connection.

What is a normal pressure range?

Typical residential water pressure should be between 40 and 80 PSI. Around 60 PSI is considered the sweet spot for good flow without damaging appliances.

What is an expansion tank?

If you have a closed plumbing system (with a check valve), an expansion tank sits near your water heater to absorb pressure spikes caused by thermal expansion as water heats up.
