Can I submerge the sump inlet under the sump water?

Razzagas · 07/10/2006, 03:59 PM

I was wondering if i could submerge the pipe from the overflow to the sump, or if it would cause any backflow issues
Thanks

Mine is below water level by design. Works great.

what do you mean by flushing action? Is that when the pipe is more then 3-6" below the water or what?

when the tubing is below 6" water loads up in the tubing and instead of a constant stream water will build up to a point its like flushing a toilet and the water rushes out all at once and then starts over again. gets awfull loud like that it will do the same thing if your durso or stockman standpipe is not set up rite too

A little back pressure (by submerging the drain line) will help quiet the drain, but too much will produce the noise and behavior described above.

A couple of inches below the sump water line has always worked for me.

Do you let the pipe end straight down? I bought my tank from someone and he had the pipe:

Touch the bottom of the sump, and

End in a 90 angle.

The sump has 10" of water so the pipe is submerged about 8". Should I have 5" off and lose the 90? It's a durso pipe. I don't get much noice except for a faint waterfall sounds. Hardly flushing...
