Hi ,I just want to know how to do the rough-in abs in basement:)

Hey firesparkplug...

We need a little more information then that..?

How about fixtures to be installed.. Are you planning for 1/2 bath or a full bath.. Are your waste pipes above floor or do they run underground?

Do you know anything about plumbing at all..? There are many special fittings, many code requirements.

Are you planning to pull a permit for this job?

Do you know anything about venting.. Lots of vent work required on these jobs...

Hey, back to you. If you really want us to help we are glad too.. but need more info.

Hey Sparky,
hi ,I just want to know how to do the rough-in abs in basement Here's a bare bones answer. Most bathroom groups are roughed in like this.
Toilet connects to sewer main or the stack vent. Lavatory connects to toilet drain and runs a vent off the top the stubout tee out the roof or revents back into a dry vent in the attic.. The toilet wet vents through the lavatory vent and the tub/shower connects to the lavatory drain and is wet vented by it. This is a normal rough in and is acceptable both by local and state codes and also The Standard Plumbing Code Book in 90 percent of the country. Check your local codes.to make sure you're not in the excluded 10 percent.. The vent off the lavatory may be run out the roof or revented back into a dry vent in the attic or if you're reventing back into a fixtures dry vent you must make your connection at least 6 inches over that fixtures flood rim. The hardest part about installing a bathroom in a "add on remodel job" is the drainage and venting. The floor has to be jackhammered up and the sewer main located. Then after you branch off the main you have to jackhammer the cement up and trench to pick up each fixture. Water will also have to connected and laid in the trenches to supply the fixtures. A bathroom group vent will then have to installed off the lavatory and go through the roof or revent back into a existing vent in the attic. In a two story house this can be a real hassle. ( if you're lucky local code will let you use a AAV,(air admittance vent) Then the basement floor will have to be patched and tiled over to hide the patches. I would get at least three estimates. Ask the contractor is there isn't some of the labor you can do yourself to cut down on the cost. (You could have him lay it out and you could rent a jackhammer and do the scutt work yourself to save on labor.) Again, I'm not there to see what difficulties he will run into with the drains and vent so I'm speaking in general terms. I hope I've given you a little clearer picture of what's involved and thank you for rating my reply. Tom
