Helping a neighbor with bathtub drain leak.
There is the standard bathtub brass drain waste with shoe, overflow and tee.
The brass rotted out in a couple places.
This coupled into a 7 vertical length of threaded 1.5 dia steel pipe, which also rusted out and broke off at the bottom thread.
Then there is a threaded cast iron trap, and a 2 nipple into a Tee fitting in the vertical vent and sewer line.
I tried a large rigid internal wrench or nipple extractor with a long wrench to remove the remaining threaded part of the 7 vertical pipe, wont budge.
I tried a 30 pipe wrench on the cast iron trap, wont budge.
I carefully applied heat to the trap, no difference. Wood closeby.
I applied penetrating oil, sitting for 2 days.
My backup plan would be to saw the nipple in half, then saw axially through the threads of the remaining half nipple in the Tee at the top, then partially collapse and unscrew the remaining part of the nipple.
The vent/drain is in an exterior stucco wall.
The tub is an old clawfoot that has been tiled in.
Unfortunately only about 12 of crawl space, and water supply pipes also in the way.
Anybody have any better ideas?
