Overflow Pipes depth into sump?
So I had a custom sump built. My question is now when the overflow pipes enter the sump chamber how far underwater should they go?

An inch or so is good.

It matters little as long as micro bubbles and/or sump detritus build-up are non-issues. Very nice sump. Virgin. It may be too late, but it is more efficient for the skimmer output to be in a chamber distal to the intake. And if the middle chamber is a refugium, you will want to put some sort of screen across the 2nd divider to keep your macro in place.

It depends on the type of drain setup u have. Looks like u have a beananimal in which case it definitely matters & u don’t want to submerge them no more then 1”. With a syphon drain the further u have the ends of the pipes submerged the harder it is to purge the air from the pipes. So with them submerged to far they will take forever to purge the air & the syphon to kick in & it may not kick in at all

My beananimal style drains go about 6" under the waters surface in my sump.

Anywhere from just below the surface to 1" below the surface.

Are you deaf or just enjoy the sound of water falling...
Feel like you have to pee all the time??

They are in the garage so the sound of water is soothing.

I’m glad it works for u but most people would have issues if they submerged a syphon drain 6” into the sump. In fact if I had to guess, I bet atleast 75 to 80% of the people who have issues with the syphon kicking in is because they have the drain pipe submerged to far into the sump

It means a syphon isn’t a syphon until it purges all the air from the pipe. Once it purges the air it starts a syphon. The further the pipes are submerged in the sump the harder it makes it to purge the air from the pipe, which is the reason u aren’t supposed to submerge a syphon drain more the 1” into the sump. Sure it can work in some cases but more times then not it causes issues

Never knew it could be a issue. The second does have some air in it. I'm running my RD2 80 watt at 70 watts and the overflow, and sump drains are very quiet, along with the pumps I'm running.

I wasn’t trying to tell u that u are wrong or anything. I just wanted to point it out being people may read the posts & think it doesn’t matter how far they submerge the pipes. Then they have issues & don’t know why. The point of them not being submerged more then 1” has everything to do with the pipe being able to purge the air so the syphon starts

It depends on the drain setup. If the drain has air in it then it isn’t a syphon. A syphon drain doesn’t have any air in the pipe, which is the reason they are silent. Beananimal & herbie drain setups have a syphon drain for the main drain.
