Silencing Infinia Frag 155.5 Overflow box

[dlemonz]

Has anyone had any success story in silencing the overflow box in the Infinia systems? The sound is driving me crazy no amount of valve adjustment and waiting fixes it. Waterbox is no help. Ive seen online some people do elbows to adjust the height of the emergency drain. I tried but i could not fit the return tubing on again after. Ive also lowered my return pump to the lowest it goes. Any advice would be greatly appreciated!

This worked for me. If you skip to 4:08 it shows what he did. I plumbed mine high enough to where I didn't need the extension he uses at the end of the video.

Waterbox overflow noise fix.
