are there any problems gluing those together without any pipe/coupling in between? provided i remove the guts of each before that? i would glue it to intake port of the 3way valve, so any residual glue that might get in should be away from the diverter.
jandy valve instructions for 1-1/2" - 2" valve says connect directly to 1-1/2" pipe and use coupling to connect to 2" pipe for some reason. even though it seems that 2" pipe would fit just fine..
