Plumbing to remote sump question....

[airmotive]

So while I’m waiting for my IM 150 to arrive, I am devising my plumbing layout....
The tank will be in the living room with the sump located in the garage (on the other side of the wall). I already have two holes in the wall from my previous tank which had the same arrangement.
However the last tank had a Durso overflow and a single return line, thus two holes. The new tank has a Bean Animal.

I really don’t want to cut two more holes in the wall. But I will do one more. The question is: What are the drawbacks of combining the secondary and emergency drain pipes into a single line? I was thinking maybe a P trap on the secondary drain line before tying in the emergency drain line so that the emergency drain line doesn’t serve as an echo chamber for any water trickling down the secondary drain.

Anybody have this sort of drain arrangement running?

You could just run it as a herbie drain and plug the third bulkhead. You lose the reduncy of the third drain when you combine two into one.

How about a rectangular hole that a Heating or AC duct would use for a floor vent?
This way is easier & more room for the hoses & can be covered with the vent if needed.

There’s a (very logical, actually) safety code that this design would violate. You can’t have free flowing air between the garage and living space. Carbon monoxide risk. (Our gas furnace and water heater are also in the garage).

I currently have two air tight ports going through the wall. I’m willing to add one more, but wifey isn’t thrilled with me cutting holes in the wall. So just trying to minimize the damage.
