Jabsco Water Puppy Repair?

[Lady Diane]

My Jabsco water puppy pump works til it is shut off, then plug it in again, and it does not work. I think the impeller stops in a way that shuts it down. What can I do to make it run properly? Right now I am not in a place where I can buy a new impeller. Information is appreciated.

If pump is idle for extended periods, the impeller may stick to the pump body, preventing motor rotation and causing blown fuses/tripped breakers.
Remove end cover and impeller, clean body and impeller, then lubricate small amount of light grease (petroleum jelly) before re-assembly.

Low voltage can also prevent motor starting.

Flexible impeller pumps must NOT be run dry, as the pumped liquid is the lubricant/coolant for the impeller.

It is also possible that you have a burnt or dead spot on the motor commutator. Could you describe how you get the pump started again? If you meant that the pump just quit, open the housing and check for blockage...

We have the same pump aboard our boat that we use to power the anchor chain and deck wash-down. I found that if the pump is allowed to sit unused for an extended period, the impellor chamber--being 2-3 inches above the water line in our case--will dry out and the impellor will sometimes stick. I remedied that by opening the impellor cover and lubricating the chamber. First with SailKote and, when that dried, with some glycerin based lubricant, and have since ensured I run the pump at least weekly.

I have also found that if we run the pump for an extended period the motor becomes quite hot and will shut itself off, although it will later restart and operate normally once its cooled. I suspect there may be a thermal cut-off in the pump motor although I have not found any stipulation of such a device in the manufacturer’s literature.

FWIW...

I have the same pump and have run hand dishwashing liquid into it several times. Maybe once a month..
