Would I still have the possible problem of siphoning in the S trap if I installed a P trap below the floor level? That's where it runs horizontal to the main waste line. The configuration would then have the S trap feeding into the P trap with about 18 inches separating them.

Gotcha! I can't go through the wall because of the double joist under the sill plate, so I guess I'll just have to use chrome and have the tail piece show behind the pedestal. Not really a big deal. Thanks for the input.

I'm renovating a small (OK, really small) full bath and have a question about the length of the tail piece for the sink drain. I have to install a corner unit because the sill plate of the only usable wall sits on top of a double joist in the basement and I don't want to carve it out for the...

The high water pressure was just a wild thought since the unit was practically brand new. It has only been in service for 1-2 months so it strikes me as odd it would go bad that fast. I suppose it's a weird coincidence that the valve stem for the tub fixture would go bad at the same time as the...

I recently renovated my bathroom and installed a separate tub and stall shower. I ran new copper pipe up a common wall between them, threaded tee's feeding the tub faucet, with the lines continuing up to the shower diverter. My problem is that occasionally the shower would drip when some other...

Thanks Mark! The best solutions are usually the simple ones. I sort of figured it would be something like that but it's always best to have a professional opinion. Thanks again for the response.

I'm installing a 36"x36" shower base in a bathroom I'm remodeling and the drain is directly over a 2"x10" floor joist. I know I'll have to notch the joist, but I need to know the best way to do that and do the least amount of damage. The drain itself will be less than 2 feet from the sill plate...

All, First let me say that this board is the best thing I have found on the internet in a long, long time. Thanks to all the information I've gotten from the various postings my wife and friends think I can fix a rainy day! ;) Here's my situation: I am replacing an old cast iron radiator...

Thanks very much everyone. After reading Terry's notes I reworked my layout. Since great minds think alike, :rolleyes: I did it exactly the way Pumber2000 drew in his diagram. The fit was a little tight, but I managed to get it all in. I really appreciate all the help.

Using the diagram as a reference, what fitting(s) would be the correct ones?

Thanks for all the feedback. After a little online research I have decided to modify my configuration. Rather than use a wet vent for the Lav, I will extend the 3" pipe to pickup the 2" Lav drain. Since everything is within 2 feet of each other I think it should be OK. It seems to simplify the...

I'm roughing in a new lav and toilet that are about 3' apart and I have a question about venting. The toilet is to be roughed in at 12" and is 15" from the side wall. I want to install a 3"x3"x2" wye directly under the closet flange so that the 2" arm extends back to the wall (through a...

Got it! After reading your reply I realized I need to setup the wet vent for the sink. Not a big deal since the walls are still open. thanks very much for your help.

Thanks for your reply HJ. Please forgive my ignorance but this is uncharted territory for me. When you say the main line into the building, do you mean the supply line or the waste line? There is a 3/4" supply line coming into the house and a 4" waste line going out to the city sewer system...

I have a 50 year old ranch with 2 full baths (A and B), one of which I have gutted and am remodeling (B). Bath (A) has a 3" copper waste line for the sink, toilet, & tub and vents thru a 3" stack. This same waste line runs about 15 (linear) feet where tub (B) ties in and the whole thing empties...
