How to Remove Unwanted ABS Drain Y?
I'm moving a pedastal sink from one wall to another in the bath. What's the best method to remove the unwanted Y fitting in the old setup and splice in a straight section of ABS pipe? Lines are currently hooked up like this:
1-1/2" line from upstairs bath drains straight down into a 2" pipe. There's a Y at that interface with another 1-1/2" fitting. That 2nd fitting immediately connects to the old pedestal sink drain Y, which then connects to the vent line which runs straight up parallel to the water drain line. Since the Y for the sink drain butts up against the Y for the 1-1/2 to 2" Y there isn't any length of plain pipe to connect to if I were to but the pipe at that location.
Is it permissible to use pipe-to-pipe rubber couplers with clamps on the 1-1/2" drain and vent lines? Since everything is rigid I don't see how to remove the old Y and splice in a new piece of pipe... which is why I'm asking the question :-)
Thanks for any suggestions.
