I replaced the above shallow well jet pump for a customer yesterday with an identical new one.

The old one had been working just fine recently but all of a sudden it quit pumping and sounded like a "bucket of bolts" when turned on. The motor "appears" to be OK. The pump is only 4 years old.

I know irrigation pretty well but not much at all about pumps other than being able to just install / replace them. I know nothing about rebuilding them; but would like to learn.

I am fairly well mechanically inclined. Is purchasing and installing a re-build kit something I may want to try or should I leave it to the experts?

Approximately how much is a re-build kit? I can buy a new HJ100S locally for $312.70.

Thanks / Regards,

Ros
