I have a Plumbing question!

[JohnS]

How deep are plumbing drain pipes in a concrete slab? My wife wants me to move a toilet back about 4 feet and add another toilet in line. I want to make sure I dont break the pipe before I am ready. any help would be greatly appreciated! Thank you.









On another note why do women want to start a house remodel right before deer season?:banghead:

The depth of the pipe depends on whether is at the start of the lateral line or the end. The riser will go through the slab, not in it. Any idea where the drain leaves the house heading to the tap? If the sewer main is out back and the toilet in question is in the front then the lateral line probably won't be too deep.
You should be good busting the concrete and then digging at least a little before hitting pipe.

Good luck is all I'm gunna say!

When you remove the toilet, you'll see how deep it is.

Mine are in the dirt under the slab, which is 4" thick. Get a hammer drill and get after it, then repour what you broke up.

when in doubt, call the pros...

There should be a minnimum of 4 inches of concrete (3.5). But the horizontal drain line should be down in the dirt.

[clintb]

Main pipe should be 12-18 inches

Thank you for all the replys! I figured it should have been well below the concrete but you can never be to cautious. Now the fun begins cutting concrete tonight

If you have a post tension slab be careful to not cut a cable. That can get expensive quick.

Also, be aware that where there is a drain line, there will be water as well. Try not to hit those.

There is no set depth for any one particular house for drain lines. When you pull the toilet you can put a tape down the line to get an exact depth to the flow line of the pipe. Then just add the pipe size to it then that will give you the elevation to the top of the line. Not really a hard job to do.

Not a hard job, just one ive never done involving a toilet. Ill pull the toilet tonight and check depth before I get busy

Very good advice.
