Hey Guys,

I need to run a water line from a meter box up the mountainside to where we're going to build our home. The engineer at the water company says if we use a 2" line to reduce friction loss, we should have around 58 psi entering the house. It's 168 at the meter. I'll most likely be doing the install myself and have a couple of quick questions.

What is the best pipe type to use for this? PVC, HDPE, etc. And what is the best place to purchase 1500 feet of pipe at a reasonable cost?

Thanks!

I would be using HDPE (POLY) pipe. You can get in long rolls and you should not need to have any joints which could be potential failure points. Plus it's nice and flexible so it will follow any curves and bends in your trench.

A roll of 2" Aquapex.

Allowing for bends in the pex run to the house. Probably closer to 45 PSIG when using water at more then 4 GPM. A little less on a second floor faucet.

Most of the 2" rolls I have seen are quite a few times smaller than 1500'. Am I correct in the assumption that if I call around to some supply houses I should be able to purchase/order a roll of adequate length?

One more question -- If I have a few easy sweeping 30 degree or so bends on the way up the hill, does that increase friction loss on the way up the hill on a 2" line, or is it negligible?

Thanks for the help!

Some jurisdictions do not allow use of PEX in outdoor buried locations, check first. Most jurisdictions allow use of HDPE, which as has been mentioned can usually be purchased in very long rolls, you need to check with a supplier, not a big box store. Make sure you get HDPE rated for potable water, I think the designation is NSF. If you cannot get a roll long enough for the job, you will need to splice the HDPE, which is usually done with a commercial grade heat welding unit, you may be able to rent it from the place that supplies the pipe.

You will lose very little friction with smooth bends, do not worry about it.

Depends on the GPM.

What kind of water pressure are they giving you?

If I'm reading your post right, you will be going up 250 above the water source. That equates to 108 PSI. Which means they have 166 PSI of water pressure where you are taping in.

That is a lot of water pressure.

He said it's 168 PSI at the meter.

Ooops.....I missed that.

It's still a lot of pressure
