    Pump housing with air in it

    I just installed a brand new Hayward 244t sand filter with 300lbs of sand. I have Jandy HP plus 1-1/2hp pump. With my old Jandy sand filter I would have to bleed the air out all of the time. Every time I would vacuum the pool, the pump would lose prime as soon as I closed the valves(with the pump off) to draw from just the one skimmer . I have a main drain and 2 skimmers. It would take 5 minutes to bleed the air out and get the air bubbles out.

    My question is . . . . since there is no air relief valve on the 244t, how do you get rid of the air?

    Any help would be greatly appreciated!


    I have yet to run the system since I'm afraid to start it up without knowing how to bleed the air out.

    Welcome to TFP.

    Don't worry about bleeding the air out. As with most top mounted valve filters, it's self bleeding. Any air that gets in the filter is going to go right out the return piping.

    Okay thanks! I also have trouble priming the pump. When I open the basket lid and try filling it with a garden hose nothing happens. It seems that the water just goes into the pool and the basket never fills up. Any thoughts?

    That's normal. If you have a suction valve you can close it and then fill the basket up with water and close the basket lid and THEN open the valve and start the pump. If you don't have a valve you can just run some water in the basket and close the lid.

    We may can provide you more suggestions if you can post a pic of your equipment pad.

    Thanks for the info! Turns out the lid seal was cracked and was leaking air the whole time. Now it primes in a minute flat.
