Water pump problem

[Keith Strehle]

It does seem a little excessive. I think I'll bleed it down and pump
it up in 5 psi increments to see where it behaves best.

One thing I can tell you from experience is that the auto-reset
breakers make a sound similar to a relay. If you hear that sound
when the pump stops the breaker is likley tripping. It is possable
that a previous owner added some additional equipment to the same
breaker and both the pump and the new equipment are too much of a
load. It seems odd that the pump would keep tripping a good breaker
but continue to provide proper preasure when running.

In the long run it is in your best interest to learn about the
electrical systems in your bird. Little things like this can spoil
an otherwise great trip. The more you know the easier it will be to
diagnose and fix this kind of problem. Of course, the forum members
are always ready to help out.

Keith,
The object is to inflate the bladder in the tank to 10 or 15lbs
when there is no water preasure compressing it. Then when you build
water preasure it will compress the bladder and thus compress the
air raising the pressure in the bladder. Now when you open the
fawcett the presure in the bladder will force the water out and give
you a reserve before the pump needs to energize. If the bladder is
pre-preasurized to 50lbs, you would need to build the water presure
to 50lbs before the bladder began to compress.

I hope this makes sense!

20 PSI works.

Thanks Gardner, that makes perfect sense when you think of the
bladder acting as a diaphragm valve. I noticed that the power light
stayed lit when the pump/water stopped this last time. I'm not sure
that means there was still power to the pump. But it does lead me to
believe it is more related to the expansion tank. Thanks to all of
you for your help.
