waste pipe

[teshaf]

I have an old cast iron waste pipe which has a hole about 2 inches. I put a patch with screen and a compound with a firmco clamp over it. stopped the leak for now. Question can this be repaired without digging the cellar floor up. The hole is about 1/2 inch out of the floor. Maybe a sleeve that will fit inside the 4 inch pipe and slip over the outside with an expandable inside and compression outside? Or is the oly remedy to dig the floor up and replace the whole pipe(I know this is prpoer but money is a factor right now)>

Sounds like you've fixed it fine (for now).

Depends on what caused the original hole, if the pipe is relatively new & it was damaged mechanically then I'd for get about it until funds are available.

If it's old (40 to 50+ years) then you probalby headed for replacement, sooner rather than later.

My 75 year old house had all of the crawlspace laterals (cast iron) replaced at ~70 years (about 10 years too late) the verticals all were ok. Plus the laterals service the laundry & kitchen....harsh chem waste (bleach, diswasher soap)

If you do any repairs make sure the internal surface is a smooth & unobstructed as possible...maybe a rolled piece of aluminum shim stock (or thin spring steel) as an inner wall form for any patching compound.....outside doesn't matter so much.

There are techniques (pipe bursting or relining) that don't require digging but they're not DIY friendly. I don't think pipe bursting will work for pipe near the surface.

cheers Bob

: I have a 75 year old house i'm remodeling and i'm thinking about having the same thing done. How much did they charge you? Did they do all the laterals, vents, and main line?
