Low water pressure results in trickling showerheads and faucets, but high water pressure can damage your plumbing system. Similar to checking your indoor air quality, testing your home water pressure a few times a year can help you identify and remedy problems before they get worse. Use this as a guide on how to test the water pressure in your home.
The Importance of Testing Home Water Pressure
Many people only think to test the water pressure when it becomes noticeably low. However, too much of a good thing can be bad. High water pressure can harm your pipe connections, water softener, water heater, faucets, and appliances. Blowouts in flex lines and washing machine hoses are also more likely, which could, in turn, flood your home.
How to Test Home Water Pressure
The only tool you need is a simple, inexpensive pressure gauge, which you can purchase at any hardware or home improvement store. Look for one with female hose threads for easy hook-up, a rubber gasket to form a tight seal, and the ability to measure up to 300 pounds per square inch (psi).
With a pressure gauge on hand, follow these steps to test the water pressure:
1. Preparation
2. Hook Up Pressure Gauge
3. Measure Water Pressure
How to Address High or Low Water Pressure
What’s the verdict? Is your water pressure too high, too low, or just right?
- If it’s too high, consider installing a water pressure regulator on the water main to ensure a maximum flow of 75 psi. Even if you already have one installed, it’s still wise to test the water pressure in your home because pressure regulators can fail without noticeable symptoms.
- If it’s too low, inspect the pressure regulator, if you have one. It should be set to 50 psi by default, but you can adjust the screw on top to improve the flow. If a pressure regulator isn’t to blame, the municipal water utility may be delivering low water flow to your home. You can solve this problem by installing a water pressure booster to improve the flow every time someone opens a faucet.
- If it’s just right, there’s nothing more you need to do. Tuck your pressure gauge away for a few months until your next test.
