Anyone know of a good 1" double union ball check valve for my return so it doesn't back siphon? Where can I buy?? Does Home Depot or lowes carry something like this??

As if now I have a small siphon hole but for some reason it still back siphons at times. Also the idea of having a hole in the return even though small I'm still losing pressure from the return pump no?
WhT do you mean raise the point of return? Ya mean put the loc line nozzle closer to the surface of the tank water??
