Joe Posted January 16, 2020 Share Posted January 16, 2020 My overflows go into the Skimz sump. They attached to pipes that are about 8” under water. Everything flows fine but it’s kind of loud. And I’m getting a gurgle from time to time. Should I cut the pipes closer to the surface of the water? Or is this how it’s supposed to be. I also thought about drilling several large holes In the pipe, all would still be under the surface of the water. That would help things flow better. Any suggestions?

Fisher Posted January 16, 2020 Share Posted January 16, 2020 Before setting mine up I had read you're supposed to keep it only a few inches below the water level as it prevents gurgling and splashing. Worked for me. Joe 1 Quote Link to comment Share on other sites More sharing options...

Cut the pipe close to the surface to give the air a chance to escape once it is pushed down the pipe. Given the length of the pipe currently, I imagine you have an air lock that is banging around inside the pipe.Sent from my XT1650 using Tapatalk Joe 1 Quote Link to comment Share on other sites More sharing options...
Joe Posted January 16, 2020 Author Share Posted January 16, 2020 Thanks for the info @Fisher & @RockyProndoa. I’ll cut it down and see if that helps. RockyProndoa 1 Quote Link to comment Share on other sites More sharing options...
Fishoutofwater Posted January 16, 2020 Share Posted January 16, 2020 Try cutting it at an angle. What do your pipes look like in your overflow. Are they angle cut? Joe 1 Quote Link to comment Share on other sites More sharing options...

Sent from my XT1650 using Tapatalk He’s obviously getting air trapped in the pipe. If you look at a lot of tank drains they are cut at a 45 angle to allow air to escape. So I asked if his standpipe is cut at an angle. The same thing applies to the drain part of it. If you can cut the pipe at a 45 with the top of it right below the top of the surface it may help air escape. Joe 1 Quote Link to comment Share on other sites More sharing options...

I'm in agreement with you about the air lock, I'm just curious why one would cut it at a 45 instead of straight across?Sent from my XT1650 using Tapatalk Quote Link to comment Share on other sites More sharing options...
crimsonvice Posted January 17, 2020 Share Posted January 17, 2020 There are a lot of pre-built sumps that are now coming with down pipe drains cut at 45*. My Bashsea sump is that way. It is even has 4 slotted cut outs at 45* going up the tube. Joe 1 Quote Link to comment Share on other sites More sharing options...
Fisher Posted January 17, 2020 Share Posted January 17, 2020 (edited) I would cut it shorter, just below the water level, and try tweaking your siphon valve to see if the bubbles are handled. If it doesn’t work you can always cut some more or just add an elbow like was mentioned. Do you want to post your drain set up, and do you know which drain is causing the bubbles? If your full-siphon is doing it tweaking your valve open more might fix it. If your trickle/durso is doing it you might have to tweak that somehow regarding air-intake. I dealt with this some and ultimately worked to prevent the bubbles rather than make them disperse. The salt creep quickly became annoying imo.

I am not running any valves. So if needed I’ll have to add them. I could also turn down the return pump a little if needed. Quote Link to comment Share on other sites More sharing options...
Muttley000 Posted January 17, 2020 Share Posted January 17, 2020 I think @Fisher is on to something with tuning the flow. Best solution is to eliminate the air instead of trying to manage it. Dispersing bubbles make tons of salt creep and headache! Joe 1 Quote Link to comment Share on other sites More sharing options...
Joe Posted January 17, 2020 Author Share Posted January 17, 2020 Thanks for the suggestions. I cut the pipes so that when the pump is off, they are nearly under the surface of the water. With the pump on, they are a couple inches under water. No more gurgling. And a lot less splashing. I think I could dial it even more. But it cut the noise in at least half.
