Thread: Backwashing

    Backwashing

    I have a sand filter and my pressure gauge is currently broken. I thought about running to the pool store and buying a new gauge. What pressure reading typically means it's time to backwash? In the past, I've just backwashed once a week and I'm sure that's not the most effecient way to do it.

    Thanks,
    Alan

    The proper time to backwash is when the pressure rises about 6psi over the clean pressure.

    So I can go home and backwash, put in the new gauge, and then watch for it to rise 6psi above that level?

    Thanks,
