Quiet Sump Drain Question

[nfored]

I have the same setup with 2 holes drilled one on each side of the tanks. I have tried many many many things. I refused to restrict the flow since I have had floods before and my goal is to keep more water in then out .

The two things that worked for me.

On the outs side of the bulk head I put a Tee, one end face up to the top of the tank the other face down to the sump. The one faces down to the sump clearly has a pvc pipe running down to the sump. The top section has a a cap with a hole drilled in it, air is still pulled into the system, but the siphon of the air is stronger at the Tee then at the tank so the air is pulled from there.

The other method I used was I put a tub int the bulkhead from inside the tank and ran the tub to the top of the tank. This has the same effect, while its a bite quiter its ugly and I don't use it any more.

You can always just put an overflow box on the inside of the tank.

Thanks guys....I drilled a hole right behind the bulkhead on the outside of the tank in the drain line and it made the drain more than quiet enough for me. I'll be buying a new bulkhead soon and doing it right with the tee and the cap, but for now, at least I know it will work.

I didn't really want to be restricting the flow for fear of the flood either, so this advice is MUCH appreciated. Thanks.

Thanks for all the advice.
