Main vents on antlers or candelabras should slope to drain condensate...HOW DO YOU DO THAT?

Roddy

I've seen several references to multiple main vent set ups (on antlers, etc.) where it states "make sure the set up is sloped / angled back to the take off". I've read others say there's a number of ways to do this. All my T's, etc. are 90 degrees and my antler or candelabra is either parallel or perpendicular to the pipes lower than it, so there's no slanting angle as referenced. How do I get that slope? A T with an angle greater than 90 degrees? Please explain/enlighten this homeowner / novice. Thanks in advance.

If you install an antler all you need to do is point the antler in the "upstream" direction of condensate flow. The Antler will then inherit the slope of the main and will not collect condensate.

swing joint?

JUGHNE

As Dan and Matt said above. However, to expound on what "swing joints" are; the first 90 off the top of the main can point in any direction, then a short nipple and another 90 can provide the slope needed. This is handy to avoid obstructions such as floor joists etc.

There are 45 degree, and 22-1/2 degree elbows in existence. 45s are probably reasonably available, the others maybe only at a plumbing supply place.

It just may take a bit of creativity to be able to use them.
