    WHO said to open the pressure valve and backwash?

    Are you sure that just didn't mean while you were refilling the filter with water?

    That is an air bleed valve.

    Re: water shooting out of sand filter

    I guess I need to explain my situation. Husband has always done the pool equipment & left me for another woman. On my own trying to figure this all out. Pool was built in 2009 & he didn't tell me when he left the SWG was not working & had been using chlorinate tablets. The hot tub is also not heating. Sand has fever been changed so my daughter & I changed the sand last night. We put the top back on and water is seeping from around the top when the pump is on. We backwashed after putting everything back together & thats when water was shooting out. Then we noticed the water seeping. Turned everything off and this morning when the pump normally comes on there was no water flowing over the hot tub into the pool. I have turned everything off & am just stumped. Way too much stress to deal with all at one time. But trying to get my pool running for my grand babies. Sorry for all the info - just a dummy trying to learn.

    If the water is just seeping then go around the filter again with 2 wrenches and give all the nuts an extra 1/4 turn.
