I’m renovating a 60’s style bathroom that had a single sink to a new vanity having double sinks. My questions deals with the cast iron drain pipes. Current configuration is a massive 3†vertical cast iron pipe with a T connection to a horizontal (except for drain slope) 2†cast iron pipe about 19†long ending in a huge nipple. From the nipple an amazing 2†cast iron pipe makes a 90 degree turn through the outside wall. What’s amazing is this last pipe converts from cast iron to a 1 ¼†tin/steel pipe somewhere in the run. The outside diameter stays the same at the conversion but is covered with clay like substance to make up the diameter except at the very end where old sink connection was made. I have loosened this last 90 degree pipe. My questions:
1. I can’t budge/remove the long 2†pipe connected to the 3†cast iron pipe. Is this connection threaded in? Which way does it turn? I don’t have any huge pipe wrench and the large rubber strap wrench I have is slipping. Can I drill a hole in the pipe insert a screw driver and turn it that way? Can I break it up with a hammer without hurting the 3†vertical pipe? Any thoughts would be helpful.
2. What is the optimum new drain pipe configuration for the double sinks. The existing vertical 3†cast iron pipe with the 2†T connector would be to the left of both sinks and I’m hoping can be left alone. From the end of the T to the middle of new sink would be about 6†then 29†to center of second sink. I assume the horizontal cast iron goes away and I convert to PVC. My plan is this rubber fitting (Fernco P22U-205) 2†to 2†goes in the cast iron nipple then 2†PVC run to a 2†T connector. T side that goes through the outside wall stays at 2� Other T end runs to the second sink and makes a 90 degree turn to the outside wall. Total horizontal run is around 36†and I’m planning a 1 ½†rise? Is this a good plan?
Thanks in advance to the professionals and craftsmen who frequent this forum.
