Jabsco Waterpuppy - Troubleshooting FYI

[abl1111]

I've had a Jabsco Waterpuppy as my 'manual' bilge pump for (5) years now. Sure it's overkill, but hey, it was my resto !

So, a little FYI: it didn't turn on this year. Checked electric - all OK, removed bronze plate covering impeller - impeller perfect. With the plate off, she ran great. Put the plate back on, tightened her up - didn't work. Loosened the (3) plate screws a tad, she worked, loosened them a bit more, worked better?! As soon as I tightened the screws home ( where they belong ), the motor stopped.

With screws loose, all worked fine even when water running through - no leaks. Thought about leaving it that way, but I knew something wasn't right. Called Jabsco in Gloucester, Mass. Explained it to them, they said right away, " the impeller expanded from winterization ". I totally doubted this. I thought it was impossible for solid rubber to do that. Bought a replacement impeller, drove the plate screws home and all works perfect.

A few lessons:

- Jabsco guys said it is better to run impeller pump dry at season end ( no water or antifreeze ), or remove impeller for season. Diaphram pumps you can use antifreeze or run dry.

- Don't doubt the pros ( I would have bet $100 the guy was wrong ! )

- Even a perfect looking impeller can be shot ( I mean perfect - it did not look at all like it would rub against the face plate, but obviously that is what was happening )

Hope this helps someone down the road.

Good advice, alb1111,
And reinforces the fact that you should replace your water pump's impeller at least every spring, whether it needs it or not...what does Fr. Frank say -- wisdom is learning from the other guy's mistakes
