Hi,
I'm getting ready to connect my whole-house water filter, and I thought connecting into water loop might be challenging, but it seems the drainage for backwash itself is pain in the ass. My pre-plumb has about 10" of 1.5" PVC capped with Charlotte 447-015 which seems to be slip fitting that is cemented onto pipe (pictures attached). I'm not sure what this is connected to as there is nothing of interest on other side of this wall (kitchen/family room, but kitchen sink/dishwasher are on different wall). I was thinking of putting a P-trap directly onto this, 22 degree joint, 20" of PVC, 22 degree joint to straighten it back, air gap on top of it, and put backwash drainage into that (I read the recommendations are at least 18" of PVC under air gap, and some air-gap products recommend 22 angle to reduce water noise).
The stupid question I have is how to even uncap my sealed drain? From what I read online it seems to options are either to cut or to use heat (which would weaken structural integrity). But even after that is done, you can see on my picture that PVC of the drain is not smooth, but is covered by either pipe insulation or maybe just some drywall insulation stuff that stuck onto it, so I won't be able to connect anything to it without somehow smoothening it. This is a 6 month old build, and rest of the piping seems to be pretty decent quality, so I must be missing something really obvious on how to connect to that drain.
