'allo,

I belong to a little brick bungalow in the midwest, built in
'54, original kitchen.

I need to remove maybe 2 sq. feet of the wall to replace a
corroded drain pipe. Wall is ceramic tile in front of traditional
plaster on steel lath. After repair of drain, I need to repair
wall. Never worked with tile before.

How to do it?

It occurred to me that I *might* be able to cut thru both grout
and plaster/lath and remove a square without destroying the tile
(if I can come up with the right saw apparati). Might this be
practical? If so, how might one *replace* the removed square,
permanently mounting it back in the wall?

Or do I bark up the wrong tree? :-)

Any help/advice much appreciated.

Cheers,
Puddin'

I assume a basement and cast iron pipe in 1954 contraction.

Yeah, it's a roof-vented cast iron stack with lead/oakum joints,
installed in 1954.

You can also replace the pipe by cutting it before the last connection to
the stack, remove the pipe from this connection then replace with PVC pipe
coming up through the floor and cabinet at the rear of the cabinet. If the
pipe in the wall is corroded it is possible the remaining pipe to the
stack
is in similar condition. A little more plumbing involved but you don't
have
to do major work to the wall.

Lost po' me on part of this.

About 4" of the bad copper pipe is exposed under the sink. There's
an elbow there, and the part that joined to PVC was badly corroded.
The other 26" of the pipe is behind the wall.

I presently have noooooooooo access to the copper/iron joint.
Assume I have to tear hole in wall.

Thx,
P

Abandon the old line and run a new line. If you have a basement to work in,
running a new line into the stack should not be difficult. The new line is
not run in the wall but up thru the floor ....into the cabinet at a location
in the cabinet that will allow enough room to get the trap into the new
waste line.

Picture all you connections under the sink, no pipe in the wall. This is
how a sink is plumbed if the sinks cabinet is not up against a wall. Quick
easy and no work to the wall is required.
