    I am preparing to replace my well pump pressure switch- the one that runs the pump when the water pressure gets below a threshold. The articles I have read say to shut off the power supply to the pump then to shut off the valve from the pressure tank to the house and drain the pressure tank. I have a shutoff between the pump and the tank. So the sequence is well > pump > pressure switch > tee to pressure gauge and to valve > pressure tank > softener > house supply. Since I am replacing the gauge and switch on the pump do I need to drain the tank? Can’t I just remove the power from the pump and pressure switch and close the valve then loosen the old gauge and wait for the pressure to dissipate? In this case water spillage is not a problem. Thanks!

    You should drain the tank anyway.

    They accumulate sediment and minerals.

    Open every valve, let the house plumbing drain.
    That will flush crud from the pipes, and will restore the trapped air chambers that help to cushion against water hammer.

    When you are done, and pressure is restored, flush your pipes and clean the aerators.

    You might need to clean the inlet filter at the softener also.

    Like Jeff says, open some faucets and drain the tank. You can do it without draining the tank if you want to take a shower at the same time. :)
