Use a Water Pressure Test Gauge to test the water pressure coming into the house. Usually the water pressure is tested before adding a water suppression tank or tank extension. This is one of the easiest home maintenance things you can do yourself. Make sure you purchase a water pressure gauge with a high pressure hand. It’s the red hand on the gauge. It will stay at the highest reading mark.
Connect the pressure gauge
Go to an outside faucet, screw on the water pressure gauge. You can also connect to the gauge to the washer water supply or the water heater drain. Make sure all the water faucets are turned off. Also make sure the water heater is not in it’s reheat cycle. When the water heater is in it’s reheat cycle, the water pressure will rise a little because of the heating of the water.
Take the water pressure reading
If these conditions are met then turn the water on and wait. Turn the water on fully. The water pressure gauge should read 50 to 60 pounds (PSI). If it’s above or below this normal range then you can adjust the regulator.
The water regulator is near where the municipal water supply enters your home. This is where the main water supply valve and water meter is also located. Check the water pressure regulator to see if it’s functioning correctly. If so, then change the water pressure to the normal range.
Use the water pressure gauge for a test range
If your water pressure is higher than 60 PSI, your water heater could have problems and maybe even explode. It’s important to set the pressure to the normal range. If the water pressure regulator is broken, you should replace it and test the water pressure again. We recommend leaving the water pressure gauge connected for a few days to gather several readings. And confirming that the water pressure remains in the normal range.
