Overflow Box

Is that little tornado thing normal on your main drain?

Herbie?

 

[NervousReefer]

Herbie?

Yup

 

[Hemmdog]

Yup

It is normal. But you want to restrict the main drain enough that the bottom of the vortex doesn’t pull air into the drain. Meaning the “tornado’s tail” doesn’t disappear in your drain.

I just opened mine a hair more for a visual of what is “to open”. This is what you’re experiencing?

It pretty much stays at the top of the water, so everything’s ok then?

Agree, and it looks like there is plenty of room for them to raise the water level in the outside overflow box to do so. That'll likely quiet the unit down too

Yep. Just the top of the vortex. Is it quiet?

Yeah but the tail is much shorter

Very!

 

[Hemmdog]

Very!

Nice! Sounds like you have it dialed in perfectly then
