This home was built in 2001.

Question #1:
I had the builder prep my toilet, shower and sink for a future bathroom in the basement which is on concrete. Are these/should these drain pipes be tide into the vent pipe for the house or do I need to do something for that? Please advise.

Question #2:
I measured 14" from the face of the drywall to the center of the drain stub out for the toilet. What are my options for a toilet flange with this situation? Will I need to break up the concrete slab to install this?

Thanks for your help

Hi Tabs...

Yes you will need to tie vents together and then run them to the vent stack in the attic (or can tie in at 1st or second floor vent if it is 2" pipe size minimum AND IT IS PURELY A VENT).

There should be a pipe for lavatory...if 2" pipe will hopefully be the vent for toilet as well as the waste for the lavatory... this is called a wet vent. Also, should be a vent for the tub or shower. These vents should connect together in the basement and run up to vent stack as mentioned. You may also have the reverse where the shower vent is wet vented by the lavatory and the toilet is individually vented.. point here is that these vents should still connect together and run full size into attic, etc. ALSO you could just have an individual vent for every fixture... here will find a box out for tub or shower.. and a pipe near it for a vent... then near toilet.. a vent... and then the lavatory pipe which will stub out for vanity and continue on as individual vent... here you would tie all these individual vents together and send 2" pipe up to tie into vent stack, etc. You will need to study basic venting if you plan to do this work yourself...quite a few codes to remember.

The 14" rough from the drywall to center of toilet flange is OK... but will be limited to a 14" rough toilet (toilet talk for distance off wall). The 14 inch roughs are more expensive and do limit selection a bit...but work fine when installed (order in advance...special order at most home supply stores).

The flange..?? Hopefully when they poured the concrete around the pipe they used a foam sleeve or something to keep the concrete off the pipe an inch or so....If they did pull foam and use an inside cutter to cut pipe and install flange...if not, then you will need to cut pipe 1/2" below concrete floor and install a special flange... this is an inside flange with a tapered rubber seal that is made to fit inside pipes for this purpose alone. The flange that fits over pipe is best, but chipping out cooncrete is hard and usually results in cracked pipe.. so try inside options first (inside/tapered flanges are sold at home supply stores).

Hope that helps. If it does, please RATE THE ANSWER below... thank you! AND do not hesitate to come back if you have more questions... we are glad to help on this site!!

So your saying the builder wouldn't have vented the toilet and shower when building the house during their prep? Are these vent pipes that I would see in the basement?

NO... I am saying that I hope he has vented the fixtures underground properly... YOU should definitely see these pipes. RE READ my earlier post carefully... very detailed in small space.. but explains exactly how to locate these pipes (unless covered behind walls)
