Rough plumbing - under metal building HELP! :-)

[ITHINKICAN]

The company doing our metal building asked where we wanted our pipe located for the plumbing - they want to do rebar tomorrow or Wednesday - we said we weren't sure - we elaborated and said we might want a total of four - toilet/sink/shower (bathroom) & sink (kitchen) - we asked for suggestions. He said we might need a plumber. A plumber offered to do the rough for $1200. I believe he will install if I can get the pipe down there and possibly assist with the installation... not sure.

In the meantime - does anyone know:
How I can do this without a plumber? ANY info?
Where would I located the pipe (distance from each other in bathroom)?
What type of drop would the pipe need to get waste safely to the septic?

ANY information would be helpful - sorry - 10 people at my desk - busy as heck - want to go look at pad site (pre rebar) - a little bit of a stressful day - no time to speak like an educated individual.

THANX!! :thumbsup:

Sadly ...... I suspect if you haven't gotten all those details figured out ....... and the contractor is doing rebar this week ......... this whole project isn't going to end well.

Go with the pro for sure;if your rough-ins aren't in the right spot&height they will be use-less.He should know the proper sizeing also.May-be you can help with the labor.You only have one chance in a concrete pour.
40 years in the business....hire a pro you won't regret it.

Do you need to pull permits? Are you allowed to do plumbing yourself or must it be done by a licensed plumber? Inspections required? If you have a bathroom in your house or at work that would work, just measure distance from the wall and fixture to fixture and lay it out the same. Don't forget the venting. The only fixture that can't be adjusted is the toilet. Are you burying water supply lines too? Wastewater plumbing needs to have 1/8" to 1/4" per foot fall.
The store that you buy pipe and fittings from may have someone who can help. Might best be left for a plumber because mistakes under concrete are costly to fix. I had to break concrete out of my basement because my contractor didn't get it inspected before the pour. Wound up in small claims court over that deal. Cost me $1000 to fix.

Sarg - thanx. We are a little nervous - but we are pretty sure everthing will be fine.
NYB - thanx. I'm leaning your way - but sure would love to save a couple bucks if possible.
KW - thanx. Not sure/not gonna. Not sure/hope not. Not sure/hope not. And thank you. And dang - sounds like we should write the check.

Thank you to everyone!! All assistance is much appreciated!

Company said they can block out a section and not pour in that area - said we can dig under permiter beam later - not fond of the idea - but would consider it if someone else has seen this approach as being successful.

Have you done any planning at all? It sure sounds like you haven't :confused2: these details should have been worked out a LONG time ago! Good luck!

I am a lisc. plumber in Illinois. The very least you do want to leave the slab out in the plumbing areas if you are not going to use a pro. That will at least let the concrete people get their work done and you can take a breather to make up your mind. Be sure they are willing to come back and pour the hole. I have been called after the owner gave up several times with the slab open like that. It was a life saver for the owner. It really didn't cost him much more than if I had done it before any of the concrete was poured. You can probably finish the walls yourself much easier than the slab. Be sure and think about if you want any water on the far side of the building before you pour. Also are you taking the sewer out the wall where the bathrooms are or do you need to go out some other way. Same for water.

KS - THANK YOU!!!! We intend to bring in the water on the one side - we didn't think about taking the waste outward - now that you mention it - the other side would be better for waste...

Unfortunately we invested a lot effort on things that seemed more important at the time but we overlooked this facet of the project - truth is we have very little intention of ever making any living quarters. It is a total last minute thought... might just do nothing at all. No worries either way. We have a house and we also have a travel trailer with beds, bath and kitchen... just considering last minute plumbing in case the next owner might want to do living quarters or if we get bored one summer and decide to do it ourself.

KS - Does the $1200 sound unreasonable. I dont mind writing the check. I'd just hate to pay someone $1200 today for something I could have done with a trip to Home Depot over the weekend. The company building the structure is flexible - so I can postpone everything a few days or even a week if need be...

We are optimistic that everything will be fine - with or without plumbing. :thumbsup:

It sounds to me like you don't know where you want the drains much less what size to make them or how to pipe them. My advice would be to call a plumber and have them do it. To me $1200 sounds high but I don't know how big of an area you are talking about, with my building I had about 10' of pipe total under the concrete excluding the floor drains which are not piped into the drains for the sink and toilet.

$1200 sounds kind of high but without knowing the particulars he may have been covering his *****. Might be less (or more) when he knows exactly what he is going to do. I didn't put a bathroom in my shop when I built it and wish I had. Even though it is close to the house, it would still have been worth the effort.
