What size & type water line to use?

[naturalgas]

I've got my electric run in trench to garage and I want to run a water line . What should I use and size. I was thinking 3/4 inch.it is about 60' to closest water line in basement I can tap into. Thanks

3/4 would be dandy.

1" would be better . . . . AND . . . you haven't told us how DEEP you are burying ??

I'd just use the continuous roll of plastic pipe like sprinkler system that was rated for potable water. Your call whether insulation was needed for frost line in your climate.

I'd probably run 1" SCH 40 PVC. That's what the well drillers are using in my area.

I personally believe the rigid PVC to be the best and most reliable I've found for the price. Make sure you install ball valve shut offs at each end, metal type are the most reliable, I've found the PVC type to freeze up and not work after several years. Also, don't forget to drop a spare line into the trench while it's open for future use.

Same basic question from two weeks ago: http://www.garagejournal.com/forum/showthread.php?t=325238

Ayuh,.... I'd run 1" black poly pipe,.....

Run 3/4" pex continuous sleeved in 2" conduit. If you ever have a problem, you can pull it and not have to dig if up.

1" black poly on a roll, that's what all of the well drillers around here use.

I would go with pex or black plastic and sleeve it. underground you should never have rigid connections like those typically seen with sch40. depending on the distance and how much water you intend to use will help determine the size. if you want to be able to wash things from a hose I would go with 1 inch. if you are just going to use it for a sink and toilet 3/4 would be fine. the only difference between the pex and black plastic is the black plastic isn't intended to be used for drinking water.

That depends on which black plastic you're referring to. Some are intended for potable water and not all PEX is rated for underground use.

So much misinformation in these "what kind of water line" threads....

Ayuh,.... No ship,.....

HDPE (poly) is what I would use, simply because of no joints. But, sch40 "pressure rated" would be fine to.

As for size, what is feeding it? If you are tapping into 3/4", then I would say 3/4".

What ever you pick, I would highly recommend a tracer wire be included.

the run of the mill black plastic pipe they sell at home depot or lowes is not normally rated nsf safe for potable water. if the pex is sleeved it doesn't matter if its rated for underground use.

I have buried a lot of black poly, they carry it in potable at box stores, never sleeved it. There is no need to pipe a pipe. Never had a piece leak.

Thanks for the replies . It is just for a hose connection inside garage to wash cars out front. It will only be about 2' deep, not enough for frost in my area(northeast) but I only care about water in the warmer months. I will add a connection that I can blow the line out with compressor for the 4-5 months a year I would have to worry about freeze up.

Some black plastic pipe is not made for constant water pressure.
I'm putting in 200' of pipe and am using 1" pvc. Found a water works supplier, that sells sch. 40, 1" x 20' bell end pvc pipe for $6.99.
Don't have freezing here.
