How do you add plumbing without cutting into the slab?

Question

I once saw in a magazine that you can add plumbing without cutting into the slab. Yet I have not been able to find anything else on it. It was in a contractors magazine. If anyone knows anything please let me know.

Answer 1

They make rear discharge toilets that would allow the drain to be run thru a wall to the main. Don't know but they may make a set-in-place toilet and pump unit that would provide an above-the-slab forced main to the main. Check with a quality plumbing supply house.

The next answer mentions a sewer sump pump but that is a big job [think a 3' dia. hole about 3' below the slab for the sump] and would involve cutting some concrete. but it would allow you to locally set fixtures and pump up to the sewer main, so it wouldn't mean cutting a long line.

Answer 2

I re plumbed a house I owned on a slab, other than the sewage and had to go through the attic/crawl space. The down side of that, especially in Florida is that the cold water heats up and has to run/waste water, until it runs out all in the pipes above.

Certainly there are more complicated, labor intensive methods such as running the plumbing from the main, directly to those rooms where its needed (burying new pie at the house perimeter. BUT in that you still have to go through whatever number of walls exist adjacent to where plumbing is needed.

Not exactly an easy DIY in any case.

Answer 3

Are you asking about a grinder pump? What is it that you want to add, a commode, another lav. a veggie sink or what? Be a bit more specific with what it is you want to add. Jackhammering into your slab isn't all that hard, just take your time and watch out for cables or re-bar. Feel free to contact me at [e-mail]. I can better help you that way. Good luck.

Answer 4

You can route the plumbing through the ceiling or through the walls. This does not include sewage plumbing. That has to go through the floor.

Answer 5

You didn't mention how much plumbing you were wanting to install. Here is another type of macerating toilet you could use.

If you are wanting to install other fixtures check out the gray water pumps section.
You also need to check your local codes.
Hope it helps.
