I have a deep well with submercible pump. It's always worked fine,
but lately on occasion it seem to not want to start on occasion.
This is on a farm. When I use small amounts of water in the house it's
fine, but when I fill large livestock water tanks (100 gal or more),
it will run for awhile, then it spits and sputters, the water stops
flowing for a minute or so, and then it begins pumping again.
I have a good knowledge of both plumbing and electrical, but I have
not encountered this problem before.
The pressure tank (bladder type) is fairly new, I replaced it 2 to 3
years ago. And I would think the pump itself must be ok, or it would
not pump at all. Nor do I suspect a wiring short, or the breaker
What I am suspecting is possibly the pressure switch having burnt
contacts, or the little hole in the bottom is clogging with crud/rust.
This switch is in a pit and not easy to get to, so before I go down
there, I thought I'd post this on this newsgroup and see what others
have to say about it.
The other thought I have is this: Could the starting capacitor be
getting weak? That's located in a shed, so that is easy to get to,
but before I replace it, I thought I'd ask. It seems to me that
capacitors are either good or bad, and there is no in between with
them, but I know they can change capitance, and wonder if that could
cause the pump to not start at times?????
That's about all there is to the system, so it's got to be one of
Anyone ever have this problem?
I should note that the pressure switch is set to
ON - 30LBS
OFF - 50 LBS
It appears it will go up to normal (50lbs), but drops down to zero and
stays there for a minute or so before it starts again.
Appreciate all help. Thanks in advance.
