Olet on Reducer

[sandypiping]

We need to inlcude a drain connection in a concentric reducer due to inadeqaute space. At the site, i have seen a lot of fittings on the reducer for vent/drain connection. Would like to know, what fittings are exactly used in this case. Believe the connection wont be perpendicular due to reducer profile.

No olet on the side of a concentric reducer can drain the pipe.

It will be below the floor of the higher pipe - which is OK, but above the floor of the lower pipe. No drain, the lower pipe will remain half-full of fluid.

Depends whether an eccentric or concentric reducer is used.
Please note that an olet welded to a reducer requires calc. acc. 304.7.2.

The OP said concentric reducer.

I agree, a eccentric reducer, flat side down, "might' drain most of the line, but it not be efficient at getting allof the water/fluids out unless the eccentric reducer was in short section of line that was a low point. Unlikely.

sandypiping,
If calculations allow (as per XL83NLs post) you could achieve a perpendicular drain with a Latrolet or an Elbolet.
See Bonney Forges O Let catalogue (Pages 24 & 25)
Hope that helps,
