Condensate Drain Question


Large reno project. Installed HVAC in attic, condensate drain pipe is pvc and drains down the side of the acrylic finish. See attached photo. Anyone have issues with discoloring acrylic over time? Client concerned that this could be a future problem. Please advise. Thx

From my experience, yes it will be an issue.

Re: Condensate Drain Question


And the fix is to reroute this pipe?

With soft water it might not be so bad. I guess condensate qualifies as soft.

Re: Condensate Drain Question


A good friend of mine might use a plumbing vent. Is there a washer box readily available?

Another option would have been to route it to the gutter's down-spout (inside, as much as possible)

Re: Condensate Drain Question


All if the new work I do they have the pipe coming out of the top of the facia and we have to cut a tiny notch in the back of the gutter and seal around it. The guy who did my central just drained it into the vent stack and haven't had any issues with it.

Re: Condensate Drain Question


With gutters one pipe is supposed to extended over the outside of the gutter to alert the owner that the pan is overflowing.

I see lots of rust from the drains.

Yes, and I saw this once.
The HO had no idea what it meant and I recommended he get my HVAC guy to clear the condensate lines with compressed air or however he does it.
I use a garden hose or coat hanger or a snake but only on my own house.

Re: Condensate Drain Question


And what clogs it? Dust from the air using water to clump up? When I clear it nothing comes out but yet it starts working again.

Re: Condensate Drain Question


That's seriously how they did it? Needs to go to ground level, to a funnel drain or condensate pump.

How crappy looking

I agree. Dripping condensate down the side of a building? That's crappy all right.

Re: Condensate Drain Question


The condensation that comes out of a condensing furnace is caustic enough to eat through copper pipes...

Seems like the primary suspects would be weak solutions of carbonic and nitric acid, and these would only form during the condensation of combustion products. The condensate from an AC will be comparable to the liquid entrained in air

Water will discolor everything and anything, no matter what the material is.

Re: Condensate Drain Question


In Virginia Beach the overflow (emergency) drain for the attic pan must be installed in a conspicuous location such as under the soffit, never in a location such as that which could be hidden by gutters. The main drain would be brought down through the crawl space and out about 2' to a planting bed.
