Q:

What is a normal residential water pressure?

A:

A normal residential water pressure is the average water pressure for a home and can be between 40 and 80 pounds per square inch. The maximum water pressure for a residence is 80 psi. A standard water pressure is important in ensuring a constant water supply and to prevent leaks.

High water pressure is a major cause of pipe damage, water waste and leaks. Excessive water pressure can also lead to thermal expansion in a residence. A homeowner can test water pressure using a gauge that is screwed onto the hose bibb. Owners of homes with high water pressure can install a pressure regulator at the meter to ensure a safe pressure.

  • Q:

    How do you troubleshoot water well problems with the pressure switch?

    A:

    The pressure switch to a well pump may shut down a well or cause the water not to flow, especially if both the switch and a pressure tank are affixed to the system. Both parts can cause an over-circulation of water, which, in turn, shuts down a system. The shut-off measure is a safeguard in case a pipe breaks while water is being pumped from the well.
