Add future water to detached garage?

[aggie113]

Of course end plans would include connecting to house septic, but... for now I may have a chance to nearly add water my detached garage. The house and garage are about 70ft from well pump/pressure tank. In a few weeks/month I will be getting solar installed and part of this will be running new trenched conduit from the meter poll (10 feet from the well) to the garage. I figure why not take the opportunity to shove some pex line in the same hole they trench for the power conduit? Thought I would see if I'm mad or crazy here before bringing it up with the installer. Everything electrical will need to be up to code, fyi. So can I save some $$ on future trenching work?

Here you can run water in the same trench as electrical, but there may be code requirements on separation.

You could simply add an empty conduit, say 1-1/2 with sweeps. Basically a "sleeve" for future PEX water line. Might keep you out of trouble with inspection. The purpose of PEX is obvious. The purpose of empty electrical conduit, not so much.

If it were me, I'd put in the conduit instead of directly burying the pex, for more protection.

Run a couple extra 1” conduit, water, and run a sani line for slop sink and toilet too. Putting all that in the trench is a few hundred bucks at the most…keeps all your options open.

Check the fall on the future desired sewer line. I ended up using a sewer grinder pump with a 2” pvc line to my septic tank along with water line and conduit for network in the same trench

Septic line is not going the same direction as the well
That would be back towards the house which is down-slope a good amount and only 40ft away. Thankfully pier and beam setup and the original (not used) septic hookup is on the side of the house facing the garage so shouldn't have any issues putting it in, other than you know, putting it in.

i just did this for mine, i tossed a 3/4 pex CW line in the power/internet conduit trench. About 75' from my house maybe 8' gain in elevation and it works fine.

Why are people wanting to use PEX for this? Get direct burial plastic well pipe and don't look back, I've run water to several barns and garages on my farm with this. Some of it has been in the ground for 25 years with zero issues. The longest is over 500 ft and one even went under a stream. Yes, I put it in the same trench as the electric (they run right next to each other in the walls of your house). I also bedded wires and pipes in stone dust prior to backfilling.

Oh, I forgot, this is GJ, where overthinking is mandatory.

I'm wanting to use pex for this because it's not going to be finished. So I'll have several feet curled up at each end for when I do finally run water to the garage. I don't plan to need more than a sink and a toilet (eventually) that it'll feed.

I used PVC (2") for the water line due to calculations on length and rise. With 2" basically the pipe had very little impact on water pressure.

I'd have used PEX - it's tougher than sch 40 PVC, more flexible... The only struggle is getting it to be straight. But once you get to sizes of 1" and above, it gets expensive.

I get max 60psi at the house so 100ft of 1" pex-a is what I'm shooting for.

1" PEX is about twice the price of the black poly pipe. All the water services and sprinkler systems by me are poly.
Terminate it with a hose barb and ball valve and connect whatever you want in the building from that point on.
