    Semi deep/shallow well
    I have a well w/ plenty of water and I want to install a second pump/tank on 1 well.. this pump/tank would serve a mobile home on my property... this well has a good water supply and is pleasant to drink... I have tried to run it dry in the past and couldn't... I don't want to supply the mobile home w my home pump/tank due to expected pressure drop in home... WILL THIS WORK w/ a T and check valves so each pump/tank will preform independently w/ a shared drop pipe and foot valve... FYI,, water is approx 12 ft from top of caseing

    Don't see how you are going to do that. Which tank would control the pump. You would be better off just piping out of the existing tank. You shouldn't see any pressure difference, the pump would just have to run more often to make up the additional water being used. A larger tank would reduce the number of times the pump would have to come on but would increase the run time. That's better for the pump life than short frequent cycles.

    Why go through all that hassle when all you have to do is tee off from your pressure line to a check velve/ to a pressure tank,(not a bladder tank but a pressurized storage tank) / to the mobile home. You will install a check valve on the inlet of your house pressure tank to insure both systems are closed and that one can't draw or feed back into the other. So one pump can, indeed, supply two systems. If you wish, a booster pump can be installed for the mobile home. Good luck, Tom

    Just out of curiosity, why wouldn't he use a bladder tank for the second tank?

    Good question. I wanted the mobile home to have a stored volume of water to draw on before it drew off the pump. A small bladder tank wouls insure pressure but not volume. If the trailer didn't have water stored in the pressure tank it would be possible for both house and trailer to make heavy draws at the same time and cut down on the volume of water to both units. Cheers, Tom
