Plumbing sump for near silence?

keithw283 · Sep 9, 2021

So obviously this is way too loud. Should I just have that drain go under the water level in the sump? The reason I put it that high was the filter sock. How can I change the sock if the pipe is in the way? Do I take the entire sock holder off? This is my first sump using a sock.

Yes, the drain in the sock needs to be underwater. Simply friction fit a length of pipe that can easily be removed when you need to take out the sock.

It's not the best picture because of the tight space, but here is my setup with the pipe pulled out to ease getting the sock out.

Yeah I knew it had to be below water for complete silence but my thought process was, "how loud can it be if it's not?" Turns out really freaking loud lol. I never used filter socks before but everyone keeps telling me they're amazing as long as I change them out or clean them as needed

That's why you typically have the main drain submersed and the emergency drain (the one with the stand pipe in the overflow) above the water. Specifically so that if/when the main drain backs up, you hear the water splashing into the sump and it lets you know something's going on.
Personally, I have my 'emergency' drain running down to the sump with a 45 degree fitting on the end and just the very bottom of the 45 underwater. That allows me to have my overflow filled up until it's just barely trickling over the top of the standpipe and not make nearly as much noise, but if it starts rushing down there, I'll hear it. Also helps a bit with water splashing all over the place.
