    Default Well Pump question

    I have a well to supply my house with water. Lately it has been running quite a bit, for a short time and turning off, then turning back on. (when water is being used)

    If you are taking a shower, the water almost pulsates, from strong stream to weak stream. I cleaned the inline filter, thought that may have been the problem, but that didn't change it.

    The pump turns off at 50 psi, and turns back on at 35 psi. When using water, this PSI drops pretty quick, almost like the tank is not filling completely up. There is an air chuck like on a bicycle, do I need to add air to the tank? I remember my grandfather doing that to their pump at times, but I don't remember why.

    Thanks a bunch

    Here is a link to a previous thread on pressure tanks...

    Sorry, didn't have a lot of time to get into details on this post, others will be along to help out I'm sure but I thought this may get you started. Hope this helps.

    If you have an old style bladderless pressure tank, it is probably water logged and you will need to add air.
    If it is a bladder type tank it is likely that the bladder has failed and will need to be replaced. You can try emptying it and pump the pressure up to 33 lbs and refill. If it holds the bladder is OK and it only need air but if you get back into the same situation in a short period of time you will need to replace the bladder tank.

    From what you describe sounds like short cycling.

    This site has a lot of good information that will help you identify parts of your system, and diagnose your issue (click on link): http://www.inspect-ny.com/water/pumprepair.htm

    then navigate to this section (click on link): http://www.inspect-ny.com/water/watertank.htm and read about short cycling (water pressure pulses).

    Then read this section on the causes of short cycling of a water pump: http://www.inspect-ny.com/water/ShortCycleCause.htm


    Signs of air loss: http://www.inspect-ny.com/water/WaterTankAirLoss.htm

    Water tank air, how to add: http://www.inspect-ny.com/water/WaterTankAir.htm

    If you don't know how to find your pump pressure gauge, pressure controls, switches and controls, see the section on Controls & Switches on Water Pumps & Tanks: http://www.inspect-ny.com/water/WaterPumpControls.htm

    There are a lot of possibilities as to what can cause short cycling besides air loss, and even if you are losing air it may not be that you need a new bladder or air tank, so replacing it is not necessarily going to correct your complaint.

    The symptoms posted by th OP point only to a pressure tank problem. No one said the tank had to be replaced. Both types of tanks were referenced and a test and/or solutions suggested.

    Evidently.....you don't understand, Jack. When you have all day to Google ad-infinitum.....every problem posted has some obscure/extremely unlikely cause & resolution.....no matter how simple & classic the symptoms.
