    I have a drilled well with a submerged pump. In the last couple of days my pump has been cutting on about every 5 seconds when the water is running. I tried adjusting the switch by tightening down on the adjustment nut but this did not help. I can hear water falling back down the pipe when the switch cuts off. Any ideas on what might be happening?

    Thanks,

    Tony

    You have a leak and the water falling back into the well is dropping the pressure fast enough to turn on the pump that fast. You need to call a plumber or well guy soon / quick and have him pull the pipe and see what / where the leak is.

    I am a little uncertain regarding the symptoms.

    Cutting on about every 5 seconds (and presumably off also) when the water is running suggests a waterlogged tank, which might mean a failed bladder or a leak on the air side of the tank.

    If there is a break in the pipe or a failed check valve at the pump, then I would expect the pressure to drop when the water is not running and the cycling would be continuous, whether running water or not.

    On the other hand, if there is a check valve near the tank, between the pump and the pressure switch, then the pipe could be leaking water AND you could have a waterlogged tank.

    if you do have a leak in the drop pipe replace it. i recommend rigid pvc pipe in 20' lenghts. most people here would recommend poly pipe instead.

    you should also have a check valve. you should have one about every 300'. it is your choice to add an extra one at the pump if you want. there is ussually one on the pump to start with.

    Why PVC and not polly?

    Would you solvent weld the peices together, how long B4 you hang the pipe after welding?

    Gary Slusser That's all folks!

    You would use threaded couplers or a special PVC pipe system with quick disconnect bell end fittings; I can't think of the name of it just now...

    PE tubing, 160 or 200 psi rated, is the best chlice.

    On the few that I do every year I have always used 100 PSI 1" PE. The deepest well I have ever pulled is about 135'. Not fun. I'm not sure anyone around here carrys 160 or 200 in well pipe. Everyone has the 100.

    pulling a pump on poly pipe is a lot of work. i find that i get tired pretty easy (i could be lazy!).

    it is called rigid pvc and comes in 1" and 1 1/4" sizes. it is od driven pipe and accepts sw fittings. however it comes threaded with plastic couplings. we replace the plastic couplings with brass ones. it takes a derrick truck to set and pull, but to me that means less labor for me.
