  • Water pressure tanks

    My new house has a well for the water and i never had one so some questions

    - what is a good pressure to have it set for

    - what should the pressure tank pressure be set for when there is no pressure on the well side

    - and right now when i run the outside house the water you can see the water pressure go high then a lot lower before the pump kicks in .

    In all my years of plumbing i never work on one .

    Thanks for your help

    You can get pressure switches for whatever you want. The air side, with the bladder empty, needs to be 2 psi less than cut in pressure. I like a 40 60 set up......no prv.

      Oops, missed one. Sometimes the nipples going to the pressure switch gets full of junk. If they are brass clean them. If they are galvanized change them and see if that helps first.

              remember its a line voltage switch, so 220 not 110, watch where you put your fingers.
              i know you know electrical safety just a reminder.

              as said 40/60 is a good cut in/cut out setting. is it a single story house? if your narrow up
              the band on the switch then the pump will cycle more often which will give you a more
              constant pressure but at the expense of short cycling the pump which is hard on the
              pump and the switch.

              look over the piping setup and make sure that the switch CAN NOT be isolated from the pump
              by a valve or other means. if that could be done then when the pressure dropped the pump
              would switch on (switch senses low pressure) but the pump would never be turned off by the switch
              since the switch is isolated from the pump and does not see the same pressure.

              I saw a setup like this in my neighbors house when I went over to help him with something in his
              basement. The previous HO had built and plumbed the house himself. apparently it was not caught
              on the inspection during construction. its not likely but something to be aware of since you are new
              to home well systems and knowing how many HOs like to DIY stuff now-a-days that they don't have the
              smarts for many times.

                  As long as the pump can reach shutoff pressure based on HP, depth, distance, pipe, stages, type............
