Rough plumbing - under metal building HELP! :-)

[Damifino]

Ithinkican, you do not need a trap below floor for a toilet, they have a built in trap, however you will need one under slab for shower.

I wouldn't nickel and dime the plumber, just ask him is this just for the rough in only for waste lines and water lines stubbed above slab.

You will also need a floor plan for him to work by, it don't need to be elaborate, just draw the fixtures where you want them and dimensions.

You will need the specs on your shower dimensions and width of vanity so he can space all fixtures with equal space between them, if coming in with waste and water lines, I would put kit. sink in wall that separates the bathroom from the inside of building.

He will also need to know exactly where the frame walls are going to be to setup correctly, he will be able to make suggestions on all above and another reason ti use him at this point, just ask him what his quote included, then when you are ready to do the plumbing in walls and setting fixtures, you will thank him and yourself the job under slab make the rest of the job go smoothly.

Good luck and keep us informed"with pics of course"

I want to thank everyone (equally) for your assistance!!

I wanted at least one additional quote. I called my a/c guy - got a recommendation - then talked with plumber #2. The discussion was a little awkward - he was rude to his helper - he was all over the place - he kept walking away and then walking back to places we just looked at but not remembering what we talked about - it was comical - I figured it was either the cold weather or the 'we just met' factor - so I ignored it. And then he quoted the same price - kind of ironic if you ask me.

Anyway, the first quote from plumber #1 had a one hour commute (he is friends with the owner of the erect company) vs the quote from plumber #2 was a local guy (referred by my a/c guy) - so I was leaning towards the local guy - figured he would be easier to reach in the future if need be. But unfortunately towards the end of the conversation he said "Oh crap" "I just realized I forgot to accomodate the 8" girt and the 4" wall" "All my measurements are off by 12". I need to refigure everything and I'll let you know the new price...

The only good part is after that wasteful and awkward but lengthy discussion with plumber #2 - I believe I have a much better understanding of what is needed - which is good too. We'll have everything suggested on TBN plus two waste pipes that exit the building - bathroom will be separate from kitchen - the kitchen will then have a grease trap (just in case) - of course both will have clean out pipes too.

Anyway, I took my uncomfortable feeling and the huge error in measurement/consideration and decided to let him know we are not interested. I called plumber #1 - his crew will be there at sunrise tomorrow morning. It will all work out! The owner of the erect company uses him for all his jobs. He comes highly recommended.

Thanx again for all the assistance!! I do appreciate it!!

I was hoping to let this thread die - no such luck.

I have a question that is kinda directed specifically to licensed plumbers or someone who is a true expert. I'm not real happy right now so I am not looking for "ha ha's", "I told you so's" or "lay opinions" - I just want licensed plumber answer to a question. Thank you for that.

Question: Is it ok to do zero work for a lavatory - then tie the lavatory in after concrete - by doing all work in the stub wall?

Kitchen - one stub for drain, one elbow, one pipe for waste. They said they would do the cleanout above ground. I had I had them do a cleanout on the exterior - it is what we originally discussed.

Bathroom -
- Waste: There is one pipe for waste - it has a cleanout on the exterior of pad.
- Shower: Drain is in the right location - measurement allowed for concrete lip, column/girts, then a stub wall - I believe it will work. They boxed the stub so we/they could move an inch or two after concrete (if need be). We're doing a fiberglass enclosure. They did one additional pipe for the vent.
- Toilet: Drain is in the right location. They used 4" pipe - they claim the flange will fit inside. They tied the vent pipe to the other vent pipe.
- Lavatory: They dug the trench. They told me they would pipe it. I walked away to talk about schedule for concrete and then I took a business call - I came back and their truck was loaded and the dirt was flat ready for the vapor barrier. They literally filled the trench back in. I asked what they were doing. They said it was perfectly legal and would pass code. They claim they can tie in the lavatory above ground using an "arm" or something like that... they say they will tie in to the vent pipe inside the stub wall. They left. I called the Owner of Plumbing Company while the concrete crew packed it down, put down the vapor barrier, did the rebar. I was trying to be diplomatic so I dont jeopardize any relationships - he said it wasn't a big deal. They do it that way all the time. He said the same thing as the crew; legal, will pass code, can fix later.

Please let me know if I need to lift the rebar and put the drain pipe in? It is what we discussed. It was evidently gonna be a pipe - there was a dang trench there when the owner was still there - I even have pictures. Anyone? Again - don't slam me. I know I waited too long. I don't need the abuse - not today. Not in the mood!

It is not unusual to tie a sink drain into the vent pipe and do it all inside the wall above grade. I didn't see anything that sounded way out of line to me. Your good.

As MarkV stated, totally legal and also provides a wet vent, when draining the lavatory the base of stack will get washed.

4" stub up for toilet, good thing as he stated a 4"x3" closet flange will fit like a glove inside the 4". It keeps the pipe solid rather than wrapping a 3" to accommodate the flange.

Not knowing your exact floor plan, I would think that is a 2 vent job, 1 for kit sink and 1 for bathroom group.

As MarkV said, you're good. Sink doesn't need a direct line and has it's own p trap so tying in to the vent stack is fine. Done that way in houses frequently. Presuming the "vent stack" at some point ties into the main 4 inch drain line which then goes out to the septic tank?

ITHINKICAN,

I'm not a plumber, in fact I hate doing plumbing, but I wanted to take a minute to say that I'm sorry to hear that you had such a rough day. Hope the evening goes better for you.:thumbsup:

 

[ITHINKICAN]

MarkV, Damifino, gerard, ustmd & dcyrilc, Thank you for the feedback!!!

I need to stop thinking about it. I know better! I know things will usually work out. I think I'll start doing my research now on how it will be best to finish up the above grade work. I'd like to do some of the work if possible. Thank you again!

Here are a couple pics.
