PVC Slip coupler
I have a 1.5 story modular and am working on getting the upper level finished. The upper floor is roughed in for a full bath all the pipes for water and drains are connected in the basement and capped in the attic. There is a half bath directly below this one. There is OSB down and I am working on putting plywood over it. The OSB was not all screwed down so I have been looking under it to see what's going on before screwing it down.
So under one sheet I discover a 3" pipe running from the stack for the two bathrooms going to the vent on the other side of the house with two slip couplers and a extra piece of PVC taped to it. Pretty obvious that these two pipes are supposed to be connected to vent the lower level half bath. (no wonder that toilet never flushed very good)
So connecting these should be pretty easy I think on one end I glue on a regular coupler then the splice piece of pipe. Then I slip a slip coupler over one side, line up the two pipes, prime and glue, then slide the coupler over. Then I discover the side I glued it from is not attached. Great this sucks so I cut it all off repeat and the same thing happens. I am making sure to put on plenty of glue but I think what is happening is when I slide the coupler over it's scraping the glue off the pipe.
I am planning on just using a mission coupler instead of the slip one unless someone can tell me a reason not to and what I am doing wrong when I am putting on the slip :)
