    Default Well problem. Need advice/knowledge

    Greetings everyone from Eastern Long Island, NY.

    Last night I noticed my well pump cycling (1 HP Sta-Rite Signature 2000 Series submersible pump,4" well appox. 40 feet total depth).

    I shut off the valve on the house side of the pressure tank and the pump kept cycling.

    Pressure tank was recently replaced, btw.

    I shut the main breaker off and went to bed.

    This morning I back pressured the line to the well with about 5 Psi of compressed air.

    Took the cap off the well head and saw bubbles in the water in the well casing.

    Is this a sign of a bad check valve or a pump problem ? I did not notice a check valve below the pitless adaptor and ground water level.

    There is about 6 feet to ground water.

    After bleeding the line of the air the pump is pumping but cycling again as it did last night.

    Any thoughts or insight on what my problem may be ?

    Thanks in advance.

    Check the inlet to the pressure switch for blockage

    Thanks for the prompt reply Tom.

    What's happening is that when I shut the house side valve off then shut the breaker to the well pump the water drains back down into the well. Not so sure it has anything to do with the pressure switch.

    Reading the owner's manual for the pump, troubleshooting section, one possibility is that there is a break in a section of the down pipe. Sound plausible ?

    Sounds to me like a split pipe in the well or bad check valve on the pump

    It's what craigpump said. The problem is in the well, either a leaking check valve or a hole or split in the drop pipe. Pull the pump.

    Appreciate the replies gentlemen. I have a call in to the well company.

    One other thing I noticed is that I have a weird white material getting caught up in the sediment filters and in the irrigation strainer. Is this some sort of algae? Last summer it was clogging the irrigation strainer (60 micron) and when I cleaned it off it had a consistency of what is best described as fiberglass insulation.

    I just swapped out my sediment filters. First one is 10 micron and second is a 5 micron. Both filters showed traces of this material.

    Any ideas what it may be?

    TIA

    Without seeing it, it sounds like calcium which could be what is hanging the check valve open

    Guess it could be calcium. The well was installed in 2005 and up until last summer had no problems. Then in July had almost no pressure in my irrigation system. As I said it turned out the 60 mic strainer was covered with the stuff. its kind of stringy. Right now the bucket that my old sediment filters are sitting in has some water in it and the stuff is floating on the surface. I'll show it to the well technician when he shows up and let you know what he says.

    Thanks again for your help.

    I would try soaking some of the white material in something that dissolves calcium, such as CLR or vinegar. Alternatively, try burning a sample in a scrap teaspoon; calcium salts will not burn, tho they may make the flame slightly pink if it is pure. If those deposits are white plastic, your course of action would probably differ.

    Calcium is usually a hard mineral deposit that has no visible crystalline structure and I've never seen it as filaments. If it's plastic material, the impellers and or diffusers in the pump are self destructing. Is it an organic material? I've seen stuff that looks like hair growing in wells before.

    Years ago I had a similar problem. If you ran water in a bucket looked like pieces of Kleenex floating around. Started clogging screens,etc. It was an impeller wearing down and causing the trouble. Mine was a 1hp Jet Pump. Pump guy fixed it. I now have a submersible as you said you do, so I am not sure they would have impeller wear in the same way as the jet pumps?? I do know it was a headache because you couldn't use the shower,washer or anything cause it would clog the screen quick and mine started this all at once.

    Yeah sounds like pieces of the impellers to me as well.

    Too lazy to look up the pump curve but 1HP for a 40 foot deep well and a 6 foot static level sounds like it could be way off the curve and shaving the impellers from upthrust.

    I would say that is a pretty good guess. Either way you need to figure out what caused it so it doesn't happen again.

    I missed the fiberglass similarity....

    I agree it is probably the impellers
