New construction temp water supply / existing well

[Timberwolf78]

I have an existing well connected to a pressure tank in the house that I currently live in.
I am building a new house right behind it, which is nearing completion ( eventually, the old one will be torn down).
I had the well company rough in before the new basement slab was going to be poured, which was a while ago.
They ran 2 HDPE pipes out to where I plan on installing the well equipment eventually. I am guessing that they trenched those all the way from near the well.
Now the situation is that I would like to have water in both structures for the transition period, until we are fully out if the old one (maybe 6 months to a year).
if I were to undertake this on my own, where would I start and what steps would I need to take to bring water into the new structure ?

You are keeping the same well, I think you are saying.

That equipment would be in the basement of the new house, right?

You would tee off the water with piping below the frost level. Your frost level might be 50 inches... check locally. Or actually, look down the casing to see where the pitless is. That is the depth of your piping.

The pressure tank and pressure switch could be at either place while you have both houses supplied with water. So draw sketch of what you want things to be in 10 years. Draw a schematic sketch of how things are now.

The tee feeding the old house could instead feed a yard hydrant when you tear the old house down.

If the contractor trenched lines from the well to the new build like you say, then you will have to buy a new pressure tank/switch to install in the new house now. Otherwise, if you install a T in the existing line, there will be a period of no water in either structure while you transfer everything over.

If the pressure switch and pressure tank remain at the old house, a tee could let both houses get water simultaneously.

As 2 pipes were installed, does that signify you are utilizing a deep well jet pump, or is the 2nd pipe intended to supply water after the pressure tank, to a yard hydrant or other building?

If planning to move the pressure tank & switch to the new house, was an electrical condiut also installed, to supply power from the new house, back to the well incase a submersible pump is currently utilized, or to allow that upgrade in the future?

Regardless of which type of pump is being utilized, suggest upgrading your well pump system by installing a Cycle Stop valve. In addition to a CSV preventing the pump from cycling which will extend the lifespan of the pump and all other system components, only a tiny 4.5 gallon pressure tank is all that will usually be needed, and water pressure to fixtures will remain constant once the pump becomes activated.

Seen them fix a hole in fiberglass. Factory defect to much damage.

I wondered if one could be used as an electrical conduit.

Yes, until the old house is torn down, then he has to transfer everything over, and have the new house without water for however long that takes. Then he still ends up with old water well equipment in a new house.

Only need one pressure tank no matter how many houses are connected.
