FatChevy Posted March 16, 2012 Share Posted March 16, 2012 I bought a new mag 12 pump today and set it up. the water in the overflow is going up and down. what do I need to do to fix thisa. I have a ball valve on the return and the drain. do I need to adjust the drain or the return? thanks Link to comment Share on other sites More sharing options...

Barelycuda Posted March 16, 2012 Share Posted March 16, 2012 I would open the drain all the way up and then throttle the return to control the surging. Link to comment Share on other sites More sharing options...
Mohaynow Posted March 16, 2012 Share Posted March 16, 2012 I would open the drain all the way up and then throttle the return to control the surging. Thats the one! Gate valves make fine tuning a breeze, but they are spendy. Link to comment Share on other sites More sharing options...
FatChevy Posted March 16, 2012 Author Share Posted March 16, 2012 well I did that and now the toilet bowl flushing is back. its like a lose lose for me lol I took the standpipe out and just ran a 1" pipe. left the ball valve for the return fully open. started closing the drain but no matter how much i close it, its still making that annoying noise.

Saltfinsax Posted March 16, 2012 Share Posted March 16, 2012 Sounds like your getting siphening in your return pipe. Most people drill a hole the size of fishtank air tube, in the top of the 90 of your stand pipe.Then slide the tubing up and down till you fined the sweet spot.

Burningbaal Posted March 16, 2012 Share Posted March 16, 2012 it might, I'd drill that hole and actually put an airline tube in it, then lead that airline so its end is at you're freak-out-it's-too-high water level. that way you'll effectively be running a durso standpipe unless the water level gets too high, then the water will cover the airline's end and cause a full siphon to really drop the level down. if you do that it's raising to a siphon and 'flushing', you're running too much gph through the return (assuming the drain's valve is full-open), so throttle back the return. take a look at the bean animal overflow, what I just described is essentially the 'durso' of his three standpipes.
