    what type of valve will let water push through the return and stops it from coming back if the return pump switches off

    thanks buddy.
    what else would work as my return pipes go a bit deep in the water and suck the water back a lot when the power is off

    post a picture of your current return so that we can comment and make better suggestions.

    Are you talking about your returns going deep into your display tank? If so you can drill siphon break holes. Drill these holes just below the surface of your water line. I will post a picture of what I mean. The holes I drilled where 3/16" and I drilled right through so that if a snail or something plugs one hole I still have another. This only allows the water above these holes to drain down into your sump.
