The way I originally set up the skanee house, all the plumbing is easy to get at in and in a relatively small area, with no second floor connections, the water line comes in from the well, it's buried about 6ft deep and straight up under the house where the pressure tank is located, the tank is directly under the bathroom and the laundry room is right off the bathroom with the kitchen directly off the bathroom on the other side, all the fixtures are within 15 ft or less from the pressure tank so it's not a major job nor is it an expensive one to do, even with the sharkbite fittings if I can locate stores that handle them.
