Replacing the drain pipe for the kitchen sink.

After about a week or two of getting the home the kitchen sink stopped draining. First thought, no problem, probably just a clogged trap under the sink, boy do I wish that's what it was.

 

 I had to keep taking apart more of the cabinets and move the fridge to even get to the pipe itself, the drain pipe had to be off to the side since the vent has to go through the roof and there were windows above the sink.

 You can tell from this and the next picture the pipe had not been doing so well lately.

 Here are some pictures of the cool pipe cutter I rented to break the cast iron pipe, you just tighten it, move it side to side to score the pipe then tighten it some more and the pipe just snaps! Tool would have cost $550 to buy but I found a local shop renting it for $12/day.

You can just see the riser clamp in this picture too, the long horizontal piece of steel, this clamps around the pipe and rests on the pieces of pressure treated wood I screwed into the studs, this keeps the cast iron vent that runs all the way through the roof from crashing down on me when I cut the pipe.
In hindsight I should not have used pressure treated wood for this as the only type of metal it can be in contact with are hot dip galvanized and stainless steel. I had the proper screws for it but had to put a piece of plastic between the wood and the riser clamp so the riser clamp doesn't rust away.

You can see some of the scale and buildup in the pipe here, the whole thing was pretty bad, and it was completely blocked at the sanitary T, where the horizontal pipe transitions into the vertical pipe.



We think she might need more iron in her diet, she really liked licking this pipe.
