Cast Iron Sewer Pipe 1950s
 
pictures below: 1950s cast iron sewer pipe in crawl space. of course, the house inspector never looked at it when i bought the house. any thoughts? i'm afraid to ask. the previous owner supposedly repaired part of the sewer line that was leaking on land (part of buyer contract).

All the old cast and steel drain line will need to be replaced at some point.
100% of the time there going to rust out, leak, or close up on the insides.

Ugh, a real mess there. I replaced mine with PVC, I had moved the toilet and the basement floor drain was just an open cleanout with no trap.
I got rid of the iron where it went to clay tile, and eliminated an old tile floor drain extending from that with a tee that was useless and had tree roots in it too. Put in a new floor drain with a trap, a wye with a plug for cleanout, and concreted back over.
Worst part was the clay tile and having to cut the bell end off to fit the adaptor.

Cast drains can last over 100 years/ in fact in my house they have been in for over 100 years.

yes they are rusty looking. If they are not leaking, why replace?

cast iron pipes have been used for centuries, right? i don't think mine are leaking...although, i'm not sure if that yellow discharge is rust or gas leaking through.

2 questions:

1. is there any life left in these cast iron pipes?

2. how much would it cost to hire a plumber to replace all of the cast iron visible?

Hold Your Horses! That cast Iron is in a crawlspace, so the exterior rust you see is probably normal.

I would most definitely replace all the galvanized steel pipe that ties into the cast Iron pipe, but I would probably leave the cast as is. Pull a toilet and take a look inside. If it looks OK, then leave it. The Galvanized steel is another story. It will be full of black gunk by now, especially the line from the kitchen sink. Use your sawsall, or right angle grinder with a thin metal cut off blade, cut it our and replace with PVC DWV. Tie in with fernco couplings, right near the cast Iron. The galvy Vents can stay, just make sure the pipe is properly supported.

Good suggestion Jagans. 2 points that concern me though:

1.Whats the drip stain on the right side of the foundation- cracked pipe?(1st picture)
2. The close nipple at the 45 is probably the weakest link since its mostly exposed threads, they tend to rust out quickest. (2nd picture)

TheEplumber, i think that drip stain on right foundation is rust because that pipe connects to the utility/laundry room, which is on the other side of the bathroom. See additional pictures above.

what would you guys suggest i do?

Yeah I think You may be right Ben. I just took a good look at photo 5, and it appears that water is weeping right through that elbow.

Great Photos by the way, Scully. Sorry for the bad news, but not really that expensive to replace, thanks to Plastic. Just imagine if you had to do it in CI again?

2 questions to all:

1. how much would it cost to hire a plumber to replace everything i see in that crawl space?

2. should i be concerned about the pipes beyond the foundation?

A plumber is going to hurt your feelings. Its a bust your ass job for him. I would think at least 5K. I bet i'm in the ballgame. Get some bids.

oh'mike 05-14-2013 07:18 AM

Best to call a local Plumber----I see a day for a plumber and a helper---

I see you are in Wisconsin---prices vary across the state---so make a call or two---Mike---

Doing that your self will cost about $100 in parts and $25 to rent a chain breaker for the iron pipe.

Javiles 05-14-2013 08:00 AM

Thats what you see, now consider what you cant see, vent stacks waste arm arms etc, how far down the main will you need to go ?
you'll need to get a plumber out to look at everything and not sugar coat anything. get at least three quotes and never go with the cheapest.
