Overflow Question!!!!!!!

[The Grizz]

Well with all the great info everyone gave me I went for it.

Had to make my own adapter to fit the bulkhead to the 90 elbow:


Glued it into the 90:


Then finished off the Hofer gurgle buster as the construction page described:


Works great built 2 for my 155 and 1 for my 75 corner. Thanks again to all for the info.

you could build a lid for the drain side that works for me.

raise the height of the standpipe so the water level rises in the overflow, lessening the waterfall noise

If you are meaning entering the sump I already have a lid because I have 2 bulk heads in the lid that attach to the drain line's

Can't do that as my overflows in both back corner's a only 4" x 4" and the drains are bulkheads drilled into back of the tank.

Take some pictures so we can get a better idea of what you're dealing with.

Is the noise coming from the water spilling into the overflow box, or from draining, or from splashing upon exiting in the sump?

A couple of picture would help... can you some how put a elbow on it to raise the height of the water in the overflow... if the noise is coming from the "water fall" from the tank to the overflow, that's the best (maybe only) way to reduce the noise... ie; stop the waterfall from "cascading" or "breaking" into a actual waterfall...

[The Grizz]

The noise is where the water spils into the overflows

do some research on Durso Standpipes, not sure about using them in a right angle situation, but that is what I use and my overflows are silent.

Durso Standpipes allow you to regulate the amount of water (water level) in the overflow so the water isn' crashing down at the bottom.

Good luck!

That might work if I take out my bulk heads and see if I can work in a 45 degree elbow, then go up but I dont have the room for a top tee and 90.
