Condensate drain.

[HawkWhiteFinger]

Condensate drains should have a continuous fall long the entire run, which we know, so why am I seeing some installations where the 3/4" pipe exits the wall level? Of course it won't back up, as it falls after the exit, but that's not falling along the entire run is it.

No and that's probably why they freeze at the first elbow after the wall.

ive never drilled a hole level even when i try plus both elbows are ninty's

 

[SafeGasInstall]

probably is impossible to drill the hole level anyway

3/4" condensate outside!!! Hope it's well insulated 😀 However i am guilty of running 11/4" straight through 🙂
