Household water pressure typically falls between 40 and 60 psi (pounds per square inch). However, if you suspect your home may have low water pressure (under 35 psi), here is one easy way to check.
One quick test is to purchase a residential water pressure gauge kit. These gauges normally cost under $10, are simple to use, and can be found at your local hardware store.
- Make sure appliances that require large volumes of water are not running (dishwasher, washing machine, sprinkler systems)
- Attach the gauge to a water outlet (for example, outside hose spigot)
- Open the water valve (fully open) and read the pressure once the needle stops moving
- Close the valve, wait a few moments, then test one more time for accuracy
- Turn the water valve off and disconnect the pressure gauge (some water will come out of the spigot)
It’s also a good idea to make sure the pipe leading to your showerhead is clear of debris, which can cause a pressure loss and showerhead flow reduction.
