How to Test Incoming Water Pressure

It is important to test your home’s water pressure before installing your water softener. Our systems have limits on the amount of incoming water pressure they can safely handle before damage could occur.

Pressure Specifications

The specifications require an incoming pressure of 20-125 psi. Due to dips and peaks from water demand throughout the day, we recommend installing a Pressure Reducing Valve if you consistently test higher than 70 psi. Our recommended ideal pressure range is 50-70.

What do I use?

We recommend using a peak pressure gauge (pictured). These gauges have two needles – one that shows the current pressure, and a second to that marks the highest pressure recorded over time.

The link below will take you to a peak pressure gauge that we recommend. We have written instructions below on how to use this type of gauge.

How do I test?

City Water - outdoor hose spigot closest to where the home's main water supply enters the house.

Well Water - faucet or fixture close to the well's pressure tank.

*Alternative (if spigot is not present) - washing machine hookup

Testing Water Pressure - Spigot

1. Turn off all water in the home - washing machines, sprinklers, dishwashers. If water is being used anywhere other than the spigot you are testing, it can result in a false low reading.
2. Remove the hose on the spigot if applicable. Screw the pressure gauge onto the faucet and turn the water on. If there is any leaking, tighten with a pliers or similar tool.
3. Make sure the water is open all the way and let the gauge record for several minutes to accurately gauge the peak pressure. If you are on city water, we recommend performing this test during the day and at night when the water demand is lower (pressure is often higher at this time).

Alternative - Washing Machine Hookup

1. Shut off the cold water at the faucet behind the washing machine and carefully disconnect the hose - there may be residual water in the lines.
2. Screw the pressure gauge onto the faucet and turn the water on all the way. Let the gauge record for several minutes to accurately gauge the peak pressure. If you are on city water, we recommend performing this test during the day and at night when the water demand is lower (pressure is often higher at this time).
