Again, this is what I've seen in other threads, not my experience since I'm currently running a sumpless system.

+1 Good advice.

OK I realized this a long time ago...kinda obvious, but I am not going to drain my tank, take it off the stand, pull the sump out, build another bigger sump.......

My apologies, I didn't see anywhere previous in the thread where you mentioned that it was not feasible to run without the check valve due to your current sump size.

No apologies necessary. My fault for lack of information.
You are totally right whatcaneyedo my mistakes in the start are a pain in the a$$ now and I will have to break it down and do it right, but it has to wait till after the holidays at least. For now...band aid.

OK you guys got me thinking, maybe I could go with no check valve if I can reduce the amount of water backflow into the sump by raising my return outlets...hmmm

Yes...that is what you need to be thinking about to eliminate the check valve.

Here is the type of Check Valve I use this

I have it mounted horizontally and it works perfect........I needed one cause Having anti syphon holes on a dart with a single outlet would spray water all over the place and when I placed them lower in the water then my sump would overflow so I had to go with a check valve.
