I am getting ready to start a new addition on our house and am contemplating using more than 1 pressure tank to help with pressure in the house. Currently we have 2 baths and a kitchen on our well with a pressure tank, water softener, and water heater all in line.

We the new addition, we will be adding 1 and 1/2 baths, a new utilty room with a sink and washer. We would be interested in basically setting up 2 distinct water systems (old and new) so that hot water and water pressure is independent.

I would be interested in adding 2 water pressure tanks, resulting in 1 at the well head feeding each section of the house with its own pressure tank.

Is this feasible? Recommended? Or just a bad idea.

I think in the long run, the extra cost for a water heater and softener is probably worth it for the added pressure and not running out of hot water.

I think you should talk to a well specialist on this one. You are going to have to figure out a way to have the two tanks talk to one another. Probably have to have a number of check valves and relays to determine which tank turns the pump on.

I would think that having the second water heater and second line coming in the house might be good, just from the perspective of having more hot water closer to where it's needed and having more volume available from the second line in. As long as the second tank is connected to the first tank, and it would have to be unless you have two wells, then I'm not sure what advantage that would give you. You cannot have two pressure tanks "independent" from each other as far as I know unless they have separate wells to draw from. Once you connect them, the pressure of the two tanks will be virtually the same. One switch will control the pressure in both of them. The only advantage would be more reserve to draw from and therefore fewer pump cycles. But you could get that by simply going to a larger tank.
