What to use for water line out to detached garage?

[mffarmall]

Make sure to put the water line below the frost line. That is about 4 feet most places. About 50 feet in Alaska. /forums/images/graemlins/grin.gif

I find that it is better to put in more then is needed. That way you can use and forget. Make sure not to put the water line in with the electrical. If you have to dig up one you will hit the other.

Probably anything mentioned here will work fine if properly installed. Nobody's mentioned backfilling yet. I like a nice bed of sand around the pipe and clean material above it. I still vote for the 200 psi black poly though.

Tom,
The 200# black poly is what was used from my well to my house. It is probably used in rural areas in Michigan more than any other type of underground plumbing. I have yet to hear of any problems with the 200# poly other than fitting leaks from not using all stainless clamps and brass fittings.

Add my vote for 200# copper tube size (CTS) poly pipe with one exception. Use compression fittings with internal sleeves rather than the inserts. Inserts have a greater chance of leaking than the compression fittings.

We went to city water while we lived in Baton Rouge. I piped in from the street with that flexible poly (polypropylene; I believe it is) line. Think I went to an inch or more in diameter there. For piping out to my barn and down the hill to my garden, I just used PVC. Most well water supply lines use that black poly to the pressure tank, after which they go to copper or other type of plastic inside the house. My house here in Va is poly-to-tank and then copper.

For water here from some rain tanks, I bought 3/4" black poly pipe in rolls of 400' and 100'. This size was big enough to run soaker hoses in my garden down below (100' vertical and 300-500' down slope, totalling near 1200' of poly all the way over to an alternative site at a little stream for water supply).

For water to my carriage house, I just used PVC (sch 160). The carriage house isn't insulated. I drain the pipes for the winter. Supply to the PVC at a surface valve is via a short length of garden hose.

Found out recently that you have to be careful in using garden hoses to drink from. Many newer ones are make from recycled rubber that can have lead in it.

This all sounds familiar. I work for Mueller co. We make water fittings for K soft copper to 200 psi PE. PE pipe comes in 2 different O.D dia for each size. You have 3/4" CTS or 3/4IPS. CTS= copper tube size IPS= iorn pipe size. 200psi PE is a good choice and inexpensive compared to copper. I have done burst test on 200 psi PE and the pipe will hold up to 700psi before it swells and fails. You will need to find a plumbing supply that sells a Mueller or equivelant fitting desinged for PE. Dont use barb fitting with hose clamps (IMOP). Mueller sells a fitting called a 110 fitting for PE applications. It is a compression fitting. It does require a stainless insert. If you cant find a supply house that will sell these fittings you may have no choice but to use barb fittings.
