I am completely new to the idea of running water so please bear with me...I live in the middle of Alaska and built a 2 small houses that I am finally going to hook water up to. I have a 1200 gallon water tank that I plan on building a 10x12 well insulated shed for to supply water. What I am hoping to gain is some advice on everything between my tank and 2 small cabins. There is a total of 3 bedrooms, 2 bathrooms with shower/tub surround, 2 kitchen sinks, 2 bathroom sinks, 2 washers, 2 toilets and I plan on a couple of hose bibs for outside water. Any ideas on sizing a jet pump, pressure tank, and hot water heater? Also because of space I plan on putting the hot water heater, pressure tank and pump all in the 10x12 water tank room. Thank you for any help anyone is willing to give me!
