Check balls fail. This is the prime example of it. If you design your system right you don't need it. I have about 2 inches of room in my sump before it gets to the top. With all the pumps turned off and when the siphon breaks.
So I don't think it's brs fault. Just a poor plumbing/setup design
Originally, I had no frag tank, and the sump would easily hold all of the water that would drain from the DT if the check broke. With the frag tank, though, I wouldn't have had the room, I was probably five or so gallons of sump space short. Regardless, the check valve was supposed to check the back flow. It didn't. The only thing that's my fault is buying the thing.
exacly you relied on the check valve to comensater for the five gallons of water your setup cant hold. once again your fault for poor design
