Where to put pressure tank in off grid home.
I am building an off grid home on a site with an existing well. I am building the house about 200′ from where the well is. The well was drilled around 1970 and has a well-x pressure tank from the same era. I don’t think it was ever used, and I believe it is functional.
I have a separate solar system for the well house, and decided to add a 700 gallon cistern. I have a Grundfos SQ Flex Submersible pump that will fill the cistern, and a pressure pump that will draw from the cistern, and supply water to the house and 3 faucets on the water line between the well and house. I have ordered a new 32 gallon Well-X Trol pressure tank (I don’t really trust a 52 year old pressure tank no matter how gently used).
So with that long introduction; where should I put the new pressure tank? I have read that it should go into the house, but to do that I would need to either put the pressure pump in the house or run the control wires from the house to the pump. The other issue with the pressure tank in the house is the faucets will not have pressure if I put a one way valve at the house.
It seems like there are reasons to have the tank in the house, but what are the alternatives.
If I put the pressure tank in the well house, the faucets will have pressure and no issue with control wires. So that seems like the best solution, but it also means running the faucets will bleed pressure off of the house when the outdoor faucets are running.
I could try to use the old pressure tank and the new together. Which would mean running control wires from the house, and connecting the pump to both pressure switches. I think the reality is that if the pressure pump can’t keep up then having to pressure tanks will not help.
I have been rambling I know but it seems like I am missing something.
