Old Houses Have Old Pipes

 

And sometimes old pipes leak.
The person working on the air conditioning
took this picture while under the house.

Lucky for us the pipe that needed replacing was behind a
wall in the mudroom, not behind tile in the kitchen. 

You might not be able to see, but a part of the cast-iron pipe was
removed and replaced with a piece of black pvc pipe.

The person who patched the wall was
willing to paint it, too. Looks great!
