Hi,
Everybody lean over here so I can pick your brains. My dad has an older slab home (from the late 50’s) in Indiana. I think the plumbing is going or gone in spots. He tried to replace the tub but the bend had a big hole in it and he’s having problems with the pipes being difficult to work with. Question is, what’s the best way to replace the plumbing under the slab? I seem to remember hearing about sleeves that fit inside the pipes to line them but I can’t find any companies that do it residentially. Do you just jack hammer the floor up and relay the pipes?
thanks
Lisa

Plumbers here find it convenient to bury the supply pipes outside the foundation, stub up and enter the desired locations via two holes in the wall a foot or so above grade. Kind of sloppy but the insulated pipes are usually hidden behind shrubbery. Works best if all fixtures are located on exterior walls but if you don't mind repairing walls you can route pipes anywhere after getting them inside.
A second method is to plumb overhead, through the attic. Holes are drilled through the top plates to accomodate the pipes and then the walls are repaired after the connections are made at the fixtures.
Also, CPVC is commonly used in repiping due to its flexibility and ease of installation, but not all locations use plastic.
There is a company or companies that do epoxy relining of pipes. It is fairly expensive, but this is the type of applications it might work in.
Go to the advanced search and check on it. It was discussed in the last 2 months.
The relining process is used frequently for sanitary lateral connections to a house, not the DWV plumbing inside.
On the replumbing through the attic, how do they keep the pipe from freezing?
I was talking about water supply lines. And according to the web site the company does do 1/2 and 3/4" lines.
Thanks!
Could you give me the web address--I'm finding loads of companies that do huge sewer lines and such, worried about finding one that does residential work.
Talked to my dad about going through the attic--he said he knew someone who put a toilet in a basement that sent its waste line up (I wonder though how a tub would fare), but I do worry about freezing, it's a one story home and Indiana as you can imagine is sorta brisk in the winter.
thanks again!

lisa.. there's "best" and "cheapest"..... in Indiana, with your freeze potential.. my first option would be to cut the slab and install new pipingMike Smith Rhode Island : Design / Build / Repair / Restore
I would cut the slab also. Do it right. The house will have serious problems to a potential buyer with pipes sticking out of the wall. I dont pipe water in an attic, because insurance wont pay a claim . Its kinda a no brainer.
