Hi there Im getting a well drilled in the next two weeks at a cabin. It has one bathroom 1 bedroom and kitchen plus a washing machine. we stay there about 6 days a month. My question is about a pressure tank, Home depot has the flotec tanks on sell for 1/2 price the next 3 days.They have like a 18 gallon 30 gallon 42 gallon and a 80 gallon. My space is limited i can fit up to the 42 gallon one but the 30 would fit better. What size do you think would work best. My well should be less than 200 feet deep and will use 3/4 submersible pump. I would like to buy one on their sell.
