After 2 years of perfect operation, my Magdrive pump just started tripping
the GFI after 20 seconds of operation. Resetting the GFI and plugging the
pump back in only gets another 20 seconds....

The intake opening of the pump is clear, but I haven't opened the case to
check the impeller for blockage yet. Is this about normal life....time to
replace the pump if impeller is clear?

Thanks for any input,

Jay

You may want to check your GFIC before replacing the pump - I had one go bad

It still seems to work fine. Without the pump plugged in, other items
plugged into this circuit work properly....

When my pump went it was the body of the pump, not the impeller.

Well, I opened it and pulled out the impeller....the surface of the impeller
has lost some of the coating and the bits of the coating seem to have gotten
between the impeller and the surrounding magnets and grooved the remaining
surface of the impeller....in short, it appears shot......

.....so......spend $30 for a replacement impeller for what turns out to be a

Anybody done the impeller swap? Longetivity of repair?

Plug it in without the impeller. If it still trips, then a new
impeller will do no good, except to be a spare.

Without answering your question, I can't see how impeller damage is
causing the
GFCI to trip -- you should be able to run the motor in any situation from
full
stall to no load without tripping the GFCI. If the outlet is OK, then
something in the pump is toast. Have you checked the cord? Assuming
this is
a true Mag pump, those guys are epoxy sealed -- it'd take some work to get
anything into the pump to the point you're getting a significant leakage
to
ground.


I think after seeing the damage to the impeller (and some collateral damage
to the inside of the impeller housing) I am going to get a new pump and skip
the repair process.

Thanks to all.....
