Hello,
I had to re-new my log in, but I have been around here before, on occassion. I have a question about a water leak in my basement I am remodeling. 1928 house
I have a main PVC drain line (6″) running across the basement and turning down to go thru the floor. Before the line goes below the slab, it connects into a cast iron boot to pass thru the slab to the sanitary.
My main question….I am getting a leak right at the floor line. The water does not appear to be coming from the PVC/ cast iron connection, but there seems to be a crack or leak in the cast iron boot.
The wonderful, previous owners poured a concrete boot around the pipe and not until I removed the floor tile did I notice the moisture.
So, is there any compound or leak proofing I can buy to apply to the cast iron boot.? Can I double up the boot, or wrap a second skin around it to help my problem?
Am I doomed to sawcut the floor slab and replace the boot? Hydraulic concrete?
One more question, what material is the best application to re-apply a sealant to the PVC to Cast iron connection that might as well be replaced to while I am doing this work? It seems to be an asphalt/ bituminous material at present.
Sorry for the long post. Do we have any plumbers out there?

it could be leaking even worse below the concrete floor.
you could cut the PVC open to inspect from the inside.
but, ultimately, you should open the floor.

get a camera inspection first, horizontal joints pipes leak lots from even small holes, a vertical one not so bad since it doesn't hold water long (unless ..) so best to resolve this before you finish the basement ..
PVC to cast iron connection is best made with a rubber coupling. Firnco is the manufacturer of many sizes and types of such couplings. And, yes you may need to cut out the cement to correct your problem.

This may be a case where money spent on a plumber would be worth every penny
Good Luck on your project
