replacing a major pipe


I have a pipe that runs from the flat roof on my old house ( acts as a rain water pipe from the roof) through three floors and connects to the sewer pipe under the basment floor. It is completely behind walls through all three stories of the house, however there are small access panels near it on all three floors. The kitchen sinks on the second and third floors are also connected to this central, vertical pipe. It now has developed a snaking, hairline crack above the basement ceiling but below the floor in the first floor apartment. The water from the rain (and the sinks) now leaks out and collects behind the wall in the basement where the pipe goes into the ground creating pooling water and making the sheetrock wet and moldy. I have tried various devices to soak up the water and some plumber's putty on the crack itself but I fear the solution is to replace the pipe,either a section of it or the whole thing from roof to ground. Is this as big a job as I fear, or I am letting worry run wild? can you advise? thanks

We are going to need pictures of this one----you are describing a main stack vent--that is being used improperly to drain a flat roof--I think?--

Is the pipe cast iron or PVC?

More info needed-----Mike---

Legal or not, you'll need to replace the part of the pipe that is cracked. Not easy if cast iron; I think it is plumber time.

The roof drain should be replaced entirely and kept clear of the domestic plumbing!

If the cast iron pipe is cracked in one location, it may be weak or cracked elsewhere, and cause more problems in the future.

In the hospital I work at they have replaced horizontal sections of the cast iron roof drain system with PVC of the same diameter and hubless couplers.

When you say it collects rain water, does it actually collect the rain water, or is it just venting out the roof and allows some rain to get in?

How big is this pipe and what kind of material is it? If it's the main stack and cast iron, you are looking at a decent amount of work here, but you don't mention any toilets flushing to it, so I am hoping that it is just a 1.5" or 2" drain that vents out the roof. If this is the case, it may not be as much work as you think, but you will probably have to touch up on your drywall skills.

depends on if it is an existing roof drain,normally it would not have other plumbing fixtures tied into it though.

Doesn't matter here if its pre-existing & goes to the sewer (not storm drain)
Its illegal, they catch it they fine you
And he clearly has stated that other plumbing fixtures DO tie into it
They've had several amnesty programs where they will assist in rerouting these systems

Theres many old apartment and commercial buildings in the omaha area built back in the 20s-30s that still have roof drains tied into city sewers,generally its not a big enforcement issue untill remodeling or other repairs bring the city inspector into the building.
As I said normally no other plumbing fixtures are tied in with the roof drains but it does happen.
