Question

Condensate from Direct Vent Water Heater Tube Routing to Outside


Hi everyone, I have a vertex direct vent water heater. Being high efficiency I have condensate I need to exit out of the house. Currently have a lil giant pump, pumping the water into a bucket. I want to route this out of the house so I don't have to empty the bucket.

Does anyone have any photos on how they are doing this?

I have a sump pump and a 1 1/2 pvc pipe headed outside. The pipe is pitched slightly outside when it goes through the wall. I was thinking of taping the hose into this pipe. I am located in North Jersey and it does get cold in the winter. Not sure if this is a smart idea also now sure if this would maybe cause freezing somehow.

Thoughts? Anyone know how to would connect my tube and not have it look like a sloppy mess?

As long as the pipe can drain easily and doesn't hold any standing water, tapping that line should work just fine.

Make sure it has some sort of check valve on it so you aren't just dumping the condensate into the sump/weeping tile.

My thoughts exactly. My sump pit takes my condensate plus the backwash from the water softener. The sump pump takes it from there.

The way i see it, why waste power and the pump by having it constantly running? If i can use gravity and no power or noise. Also the water is slightly acidic so who knows what kind of effect long-term that would have on my pumps.

I am probably going to install a water softener soon, how much back wash does your system put out? I was thinking of draining that into my sinks trap.

If we have to use a condensate pump for that application, we just run it to the nearest gravity drain. (or outside if there's no other option) The pumps that we buy have a built in check valve but slightly drain back on the off cycle. (about 12" or so)

Cheers!

If I read my unit's manual correctly, 3 backwashes per cycle @ 5 minutes each x 1.5 gpm flowrate = 22.5 g.
