Thanks Cary! One more question that I do have is that we have an old Galv. pressure tank(not a bladder tank) that is about 40"wide by about 72" high and the well pump size is 5hp. The shop also wants to replace it with two 81 gallon bladder tanks but doing some research two 81 gal would make the 5hp pump cycle for only 60 sec. instead of the optimum 120 sec.unless I am calculating wrong. I would think that I would need 4 81 gal. tanks for the 120 second cycle is that correct? Also the tank was put in back in 1980,what is the life expectancy of one of those tank? The main reason we are redoing the well system is we have tannins in the water and are going with a seperate tannin media filter along with our regular media filter/softner and need to put a water holding tank in for slow filteration so that the water gets filtered properly and then we have to reestablish pressure again. Is there any other way to establish pressure without using a jet pump? Thanks for all the help!

 Hi, I just have a question about the Frankline subdrive inline 1100 pump. I am going to have our pump house all rebuilt with a new system ( our now is over 30 years old and pipes are rusting out and so is the old galv. pressure tank) The question I have is the company wants to instal The franklin 1100 pump to feed the 6 houses on our well and the farthest house is about 400 feet away and this seems to be a bit of a small pump to me but I am not a well expert, what is your guys opinion? This pump is in conjuction with 2 pressure tanks befor the filter and a water holding tank then the pump to feed the houses. Thanks!!
