    Just a WAG but it sounds like the filter is filling with water. Does it have an air release valve at the top? If so, open that part way until water squirts out.

    How long did you leave it on listening to the noise? 10 seconds? 2 minutes?

    Are all your valves open back into the pool?

    Re: Filter issue..please help

    Here are the instructions from my hayward s220T sand filter...not sure which model/brand you have but most sand filters follow the same concept

    INITIAL START-UP OF FILTER

    1. Be sure correct amount of filter sand media is in tank and that all
    connections have been made and are secure.

    2. Depress Vari-Flo control valve handle and rotate to BACKWASH* position. (To prevent damage to control valveseal, always depress handle before turning.)

    3. Prime and start pump according to pump instructions (be sure all suction and return lines are open), allowing the filter tank to fill with water.WARNING: ALL SUCTION ANDDISCHARGE
    VALVES MUST BE OPEN WHENSTARTING THE SYSTEM. FAILURE TO DO SO COULD CAUSE SEVERE
    PERSONALINJURY.Once water flow is steady out the waste line, run the pump for at
    least 2 minutes. The initial back-washing of the filter is recommended to remove
    any impurities or fine sand particles in the sand media.

    4. Turn pump off and set valve to RINSE position. Start pumpand operate until water in sight glass is clear—about 1/2 to 1minute. Turn pump off, set valve to FILTER position and
    restart pump. Your filter is now operating in the normal filtermode, filtering
    particles from the pool water.

    5. Adjust pool suction and return valves to achieve desiredflow. Check system and filter for water leaks and tightenconnections, bolts, nuts, as required.

    6. Note the initial pressure gauge reading when the filter isclean. (It will vary from pool to pool depending upon the pump and general piping system). As the filter removes dirtand impurities
    from the pool water, the accumulation in thefilter will cause the pressure to
    rise and flow to diminish. When the pressure gauge reading is 8-10 PSI
    (0.55-0.69BAR) higher than the initial "clean" pressure you noted, it is time to
    backwash (clean) the filter (see BACKWASH underFilter Control Valve
    Functions.)

    NOTE: During initial clean-up of the pool water it may benecessary to
    backwash frequently due to the unusually heavy initial dirt load in the water.

    KEEP SAFETY LABELS IN GOOD CONDITION AND REPLACE IF MISSING OR DAMAGED.

    IMPORTANT: To prevent unnecessary strain on piping system and valving, always
    shut off pump before switching Filter Control Valve positions.To prevent damage
    to the pump and filter and for proper operation of the system, clean pump
    strainer and skimmer baskets regularly.

    also my filter does not have an air release valve...the above procedure allows the filter to fill with water and let all the air out...I also had swishing sound until the filter filled...once I follwed the steps and switched to filter, it was nice and quiet....Please check your sand filter manual if you still have it to make sure you can follow my suggestion above

    um, i dont have air release valve on filter. The swooshing water sound has been consistant. some water is dripping out of top, did i add too much water to filter? there is also air bubbles in pump window, everything is tight dont know how air is in there.

    Your strainer basket lid isn't tight, needs a new O-ring or one of the drain plugs in the pump is loose. You could also have a low water level in the pool.

    as mentioned above...most sand filters do not have an air release valve...try the suggestion above and let us know how it works.
