Motor for JabscoWater Pump Failure

sailingmum · #1 (**permalink**) 10-09-2011

The motor on the pressurized water system is going down again, I put a new one on late winter and now it wants another one. It can't be a voltage drop the run is only about 6'. However, if anyone has any ideas I am all ears. It is definite that it is the motor as I see a huge spike in the voltage when the house system tries to throw power to the motor. Jabsco motor. Even if I replace the motor I'd like to know the cause or was it a bad motor. Frustrating and costly. Any ideas
Thx Suky

two thoughts. Wire to small. pump clogged or supply partly clogged causing increased work.

I am not impressed with the Jabsco water pump. Many times the permanent magnates exfoliate and block the armature from free movment. ShureFlo makes a better pump. If you look around there are probably even better alternatives like some of the sealed magnet pond pumps...........

If those Jabscos keep quittin' on ya, buy a Shurflo. My 25 year old one still works and I bought a replacement three years ago.

If you're spiking voltage and amp draw, it's either the wire size or the connections, or both.

Shurflo is definitely the way to go.

I just had to completely disassemble the motor on an almost new Shureflo pump. The brushes in the cheap plastic housing were stuck. This pump was a replacement for the old PITA Jabsco. IMO any of these pumps seem to be the most unreliable gadgets on the boat. Glad I have a manual sink pump as well. They seem to be a constant source of aggravation/revenue for the manufacturers. In contrast, pumps for home use are about the most reliable piece of utility equipment. Moving water is not rocket science. This is a case of grossly overpriced planned obsolescence, the time period for digging into your wallet again being around 1 season.

There are magnetic induction pumps that are very reliable and completely sealed. Look at Pond Master and the like.....ShurFlow are good pumps. I have run them with long duty cycles for years before having to replace.
