Overflow gurgle

[Troylee]

Seal the durso make it a full siphon and adjust your drain accordingly... A 1-1/2" drain can handle 3000gph if I remember correctly at full siphon... Your not getting to much flow that's not your problem... If anything your drain is submerged in the sumo to much back pressuring just my 2 huh..

According to this site, the rigid PVC 2" drain handles gravity fed rates up to 3300 gph and 1.5" drains handle gravity fed rates up to 2100 gph:

I use a gate valve on the return line because sometimes it will gurgle due to the pump returning water faster than the drain line can drain it.

Your drain pipe isnt big enough

So many suggestions lol
I had a ball valve on the drain but found it needed to be wide open just to keep up with the pump throttled back and at that time the drain was barely an inch under waterfall gurgled so took out the ball valve then added the T thing to try to give the air a way to escape that didn't work either

I'm not able to get behind the tank or into the bottom of the Overflow box so not sure how I can add a second drain without draining the Overflow box ie a lot of trouble lol

After throttling back even more it only gurgles every ten minutes or so lol better than ever few like before but it still causes a lot of splash in the lid of my sump

Its not getting full siphon with air it needs to be sealed completely
