    Exclamation How should I be vacuuming to waste? Urgent request

    I have dead algae in the bottom of my pool that I want to vacuum to waste and I just used a flock. Everything worked and the junk is at the bottom of the pool. I set my multi port valve to waste, hook up my hose and vacuum as normal. I notice that water is going out the waste line as it should, but it also goes through the return back into the pool. I only have 1 return and the junk is getting back into the pool because of this. I marked this as urgent as I need to vacuum fully before the flock stops working.

    i have a ball valve on the hose going to the return and I tried closing it so no water would go through. The water then started to seep through the plastic site just before the waste port.

    what are the exact steps I should be doing in this situation?

    thanks ahead of time!

    There is a problem with your mulitiport valve if it is letting water into the return path when it is set to waste. You probably have a bad spider gasket. For an immediate solution try vacuuming to waste by siphon method. Here are the instructions:

    fill hose with water- start at one end, attach to vacuum to weight/hold underwater.
    push hose underwater along the length, so it fills entirely
    when you reach the other end, water should bubble out of it
    Hold both ends under water
    grab the middle of the hose, throw it over the side so a loop is hanging lower than the water level in the pool
    work back the length of the hose away from the vacuum head
    throw the end on the ground where you want the water to drain
    start to vacuum!
    when done, lift vacuum out of water to break suction, and drain to other end so gunk doesn't come back into pool

    I just bought a brand new head for my sand filter via Hayward. So is this defective then?

    when I vacuum to waste there should be no water going back through the return?

    ill try the siphon method as well!

    A quick solition could be vacume to filter then just clean(or back wash filter) till you get the gasket or what it may be fixed on the multi port.
