Plumbing and a Concrete slab

[DCarr]

I just bought a 1/2 acre lot that adjoins my current property and will be putting a 40' x 60' metal building on a slab on it in 2 years and am trying to get all my information and figure out my choices now.

I live in TN., so I dont have to deal with the coldest of weather but it does get a bit chilly here.

I am planning on having a full Bathroom, kitchenette and a single spicket outside.

How do I go about running the copper ( or ?? ) water lines ? Will the main line have to be laid down and come up exactly where needed before the concrete is poured ?

Or do I run the main water line outside underground and come up for the spicket and then continue on to where the kitchenette / bathroom will be and go into the slab there ?

Any info would be greatly appreciated.

IF you want the water lines to come up inside the building, run your copper inside the concrete on an exterior wall. Make sure you compensate for the 1' 1/2" metal ledge. From there you can go overhead with water. That way there is no exposed copper running up outside the building, just a spicket sticking out of the wall.

I did not allow for any water lines when I built my 60x60 metal building. I ran water lines to and past the building, putting "no freeze" type faucets that extend deep down in the ground to the water line, and I brought the water line up just outside the slab and thru the wall of the building. I used 1" PVC and put a 1-1/4" PVC over it (one just slides over the other) as a protective jacket (weed eaters will tear up a PVC pipe) but later I wrapped the line with insulation and took some 4" thinwall "crush" pipe and a thin wall DWV elbow and glued them together, split them down the middle and made a protective jacket over the line/insulation. Its never frozen (south side of Atlanta) and we've had some pretty cold days and nights. Best to go ahead and bring the line up inside however.

I would (and did) develop a plan for where the water was to enter the garage (near where a hot water heater would be and near where the sink would be). Even more important that the water however is the drains for toilet, sinks, water heater pressure relief valve, clothes washer etc.) Before the floor was poured and even before the backfill was complete, I had a plumber install all of the drain pipe and a 3/4" flexible copper pipe under the footer and wall, mark its location on the outside, and position the drain pipes and water pipes under the floor. All of them are on INTERIOR walls and in an area that is always going to be heated. Then the back fill was done, the floor poured the building built, and then the plumber came back and connected the water feed line and the drains to the house, and plumbed the inside of the garage.

Spend a lot of time in the planning stages. If you have never done one, draw a plan of your finished garage and place a scale model of each sink, toilet, shower, clothes washer etc, that you will ever want. Make sure you are okay with it before you have the floor poured, or "you'll be SORRY"......
