After some trial and error, I was able to quiet my sump and overflow box's down to a very quiet setup. I thought I might share them.
Overflow box's:
Standpipes. Veryeffective and easy to make. I even was able to make one for a duel 1" box.
Overflow box lids. Just a piece of plexi to cover the top of the box where the standpipe is.
These 2 things make the overflow box near silent.
Sump:
Overflow drain to sump. By using 2 45 degree angles, I was able to direct the flow in a mannor which keep the air bubbles from "gurgleing". Kind of in an "S" shape where the bottom half is under water. (It does generate a little head preassure, but it is so well worth it).
In sump skimmer:
Drain lines are 1/2 pvc tubing that drain down side of sump just at water line, not below otherwise it will "gurgle" a little.
Return Pump vibration:
This was easy, I took an old shoe, cut the rubber sole off, cleaned it, cleand it again, and placed it under the pump.
Waterfall sound in the PVC junctions and corners.
This is the sound of the water flowing through the PVC.
I took an old pair of denim jeans and wrapped the junctions and corners twice with the denim. This worked like a charm. Of course it is only in the out of water areas.
With all of these improvments, I made my filtration system so quiet all I hear is sound of my fiencee snoring. Hmm, maybee I should take some off.......LOL
Hope this helps.
