    Filter pressure vibrating

    I have inground pool with a sand filter, from last couple days, after start the pump, the filter and heater vibrates and pressue gauge reading is fluctuating very fast. If I put filter to recirculate stage, the problem went away. If put to filter stage, it happened again. I already back washed filter, water level is good too. When vibrating, there is still water return to pool. any idea why this happens and what's solution to fix this?

    Welcome to TFP

    You may need to do a deep clean on your sand filter, it may be channeling and making the filter vibrate..

    What brand and model of filter do you have?

    Have you done anything to the multiport valve lately?

    Do you see any air in the pump basket?
    Do you get any air out the filter air bleed?

    I would also check for trapped air in the filter. Also check the line between the pump and the return for obstructions.
