Just some picks of the job I believe I will be on for most of this summer. We did two bathroom groups and bit more last year at this location and the landlord has found a tenant so we started the buildout on an arcade type spot in half the space. Going to be two full service bars, two bathroom groups of 16 w/c each and a handful of other fixtures. Figured I’d share some pics of the work since I have put forth zero content since joining.

We set 4 urinal and 12 wc carriers, core drilled and stubbed plastic and copper to the floor below so far. Will be probably finishing this second floor next week drilling for and setting floor sinks and floor drains and finishing up a family restroom we started today.

I asked the same question and the answer I got was that there was one c.o. called out in the drawing so it got one clean out.

So short answer my master gives zeros f’s and ordered one c.o. tee because he knew he had to have a c.o. where it was accounted for.

More detailed would be the architect didn’t take into account that there was no way to catch seven carriers to the right of that clean out because we need fall. The drawing called for one drop, one clean out. We had to break the carriers into two drops, but the second cross’ clean out would have nowhere to exit the wall because of the proximity of the carriers and the backing for the partitions that is yet not installed as of these pictures. Little bit of bad planning and little bit of lack of desire led to something we’re not required to put in by code to be left out. I dislike it but it’s not wrong per se. As my boss would say “I guarantee you I(he) will never have to pull one of these toilets to snake it!”

Nice looking work but I absolutely hate ferncos!!! I always use mission couplings with the solid stainless jacket (not no hub bands). I’ve seen too many in my life that have sagged.
I I’ll take a pic tomorrow of an example but we support any run beyond carrier to carrier to prevent sagging. Finished up a family bathroom with a tight chase with a double wye laying flat that catch carriers at the far corners of the ADA bathrooms and lavs, with strut coming up from rod to prevent any chance of sag.



also thanks to everybody for the kind words I’m glad I’m learning from someone who is both skilled and takes pride in our work.

I certainly can’t take a lot of credit for the finished product because even though I do a lot of the work it is with close guidance and heavy scrutiny. Some of it takes two tries (and maybe three on occasion).

I brought up the fernco’s on the first commercial job I was on. I agree they are not approved for above ground horizontal work. Clearly stated in the code book. With that being said, we’ve not had any inspectors here in the county have an issue or call them out in any way.

As far as fire caulking, all penetrations are to be fire caulked specifically to the effect to stop the spread of smoke. This is a three story mixed use space with a very in depth sprinkler system. I do not know much about building codes pertaining to fire proofing beyond us caulking the holes above and below the decking for smoke control. Sometimes we have to plenum wrap our pvc in plenum spaces or hang cast iron instead.

The single carriers are 3/8 power studded to the concrete in three places, and the back to back in four.

Those Fernco's are WRONG. They should not be there. Pvc/ci adapters and no hub couplings are correct. I bet you don't put a 10' head on those connections.
Depending on whether or not the brand we supplied meets the c1461 standard, I reason that they are actually not specifically prohibited, but given the spirit of the rest of the sections regarding mechanical couplings I tend to agree with you none the less.

I can’t find what I was looking for specifying any above ground horizontal flexible couplings shall be shielded and properly supported on both sides within 18” or something to the effect.

I’m still learning how to effective use and understand my code book but here is what I mentioned earlier about supports. This is an addendum in Allegheny county :

it’s confusing because I don’t see any standard mentioned for any unshielded coupling above ground, but here it shows a lean in that direction. Sorry for the barrage of responses but this is something that piqued my interest both at school and in the field in practice. Yet I could never get a definitive answer on the subject.

Our inspectors have never had a problem with the methods we use just to clarify, but I’m always looking to have the knowledge to do it right, do it better, and understanding some of the reasoning why as well.
