OK....pulled the old CI tub.
Messing with the old bathtub "T" fitting (that connects overflow pipe and main tub drain with outlet drain pipe) (is there a proper name for this T?) I notice it's loose...the whole pipe is loose...
...dig down in the blocked-out area of slab, and find that pipe is 1.5" galv steel, rusted out...dig it up, unthread it, and replace with 1.5" ABS pipe (into CI p-trap)...which ABS has 1.5" pipe thread fittings top and bottom...top one I ended up having to shorten the thread length (it's still adequate) and FILED a flat ring on the top where I cut off the threads...
Put new T fitting kit and non-CI tub in....
NOW the problem: I can't get the 1 3/8" outlet pipe from the T to the ABS fiiting to seal...it weaps water when I drain a full tub ....this joint should be water tite (constriction in drain line is a separate issue for me)
The plumbing compression coupling / nut I'm using is for 1.5" tube...is this my problem?
Is the flat ring for the ABS fitting incorrect and preventing the necessary distortion of the seal?
Are there some sort of super seals I can find to seal this joint?
Thanks for any advice...I need to move forward with this job...
