Glass holes overflow kits

[thirty6]

Anyone using them find, them a bit loud?

I paid for the cover on the overflow box, not making much of difference in noise, just wondering what other people think. Ideally, someone came up with a simple solution and will post

Got one on my 225, yes they are kinda noisy, we don't mind much though in my house, don't think theres much you can do besides fiddle with the air tubing.

I have the 1500 GPH box, I use gate valves to throttle them down a bit..I set up an emergency overflow just in case . But it is DEAD SILENT!!!

I've gotten mine pretty quiet by moving the air tube up and down.

The CPR overflows are amazing. Virtually silent when tuned right using the the air tube and pre filter. It also includes a cover to put on top. Very very pleased with mine.

Joe told you mine are loud too

Sent from my mind.

They're definitely loud and tough to quiet down. Most overflows are though to be honest

I bought the cover that goes with unit, i have the 1500 as well. I don't think much can be done as it's just a big pipe with water flowing through.....is what it is i guess. I like the look overall, sure I won't even notice when tank is cycled and has some life in it

you could insulate the drain line. either wrap it or try to find big pipwe insulation if it the water rushing sound thats bothering you
