is there any way to repair a cast iron sewage pipe that has a hole in it?

Question

my sewage pipe has a whole in it and its leaking sewage under my house how can i fix it with out replacing it

Answer 1

Im a Plumber 20yrs now So here you go.
You should replace only that section (Thats the easy way)
But if you want to just patch it there are some things you can do.
If the hole is not big. Use a no Hub (or Fernco)
Lets say its a 4 inch pipe
At home depot they have 2 kinds on rubber boots
1 Kind have 2 clamps on the ends
The other is a large metal band over the whole boot
This is what you want to use.
Unscrew the matal band with a 5/16 nut driver
Use a SHARP KNIFE and cut the boot long ways
Make sure the pipe is clean and slip the boot over the pipe Make sure the cut section is oppsite of the hole
Then slide the metal band over and screw it down tight.
There are other ways of doing this But I dont know why the hole is there or if you put a hole in it to unclog the line.
If that was the case I would say get a saddle tee and make good use out of the hole and tuen it into a clean out for the line.

My recommendation, I know you said without replacing it, but I need to say it. I would go ahead and replace it if at all possible with PVC. Just two days ago I found out my house I just bought had a leak in the sewage pipe between walls. We tried various things, but it all came out, yes, we had to dig into the wall because of bell joints. Good thing though, because this leak was actually the pipe broke in half, along with a 3 foot rust hole from another crack.

To save you time (from other leaks) and money later on, replace all with PVC if possible, we only spent two days and 200 dollars to do it, although the whole house is in a remodeling state.

It is also a good opportunity to revamp the system if you have a crawlspace. I took out a few bends from the old cast iron system and ran a straightshot from the bathroom to the outlet junction. Remember to keep the correct angle on the pipe, I can't recall it exactly, it's something like 1/4 inch per 10 feet of pipe.

You could put a "band-aid" on it. Wrap duct tape all around the hole, just be advised this is a temporary fix. Your best bet is to cut the pipe in two, right at the hole, and install a NO-HUB band. This is a specific coupling made to connect 2 pieces of cast iron together. You will need to know what size the pipe is, in order to purchase the correct band. It consists of a stainless steel outer band with 2 radiator type clamps to draw it tight, and a rubber gasket, that goes on first to seal the pipes. It requires a 5/16th socket and wrench to tighten it up. Just make sure the exterior of the pipe is clean. I hope this helps!

Answer 4

There are a variety of "clamp-on" type pipe repair solutions. They are typically lined with heavy rubber sheath and screw down hose clamps to apply pressure to the pipe on either side of the crack and stop further leakage. You don't mention the location or diameter of your pipe and this will be a factor in determining the feasability of such a solution. Depending on the location and size of the crack, there are some good "dry-weld" products available at OSH and Home Depot. Replacement is usually the best option as soon as possible. Cracks seem to always expand and lead to larger fissures.

Answer 5

Home Depot or, a plumbing supply sells repair patch kits. The patch is metal with a rubber seal inside and pipe clamps . This will easily repair a drain pipe .

Answer 6

I have to assume that your house is, in some way, above ground, you have to repair it from the outside of the pipe. Go to a hardware store and purchase epoxy putty. Mix it in your fingers as directed and rub it into the leak, work it in good! This stuff is amazing and I have had excellent results.

Answer 7

MIRACLE CHILD ANSWERED THIS QUESTION you need epoxy putty not a rubber and metal clamp those are for steam lines and twice as expensive and takes 20 min to put on putty takes 3 minutes to pprepare and install and is forever "harder than steel in 10 minutes" it says on the package
