The water pump in my 2015 T@B has worked fine for nine seasons. I last used it about three weeks ago. While winterizing a few days ago I flipped on the pump while the system was depressurized, and... nothing. No whirr, girgle, hum, crunch, or sound of any kind. However, there was an obvious current draw on the battery so it was trying to do something. This likely rules out a power supply or pressure switch issue, and suggests a seized motor, but it seems odd it would quit just like that with no warning. (Maybe. There's at least one old discussion here when somebody described a similar abrupt failure.) The pump is currently on my workbench awaiting an autopsy.
So, I'm asking...
- ...has anyone experienced a similar failure with their pump? If so, did you figure out a resolution short of replacing the pump?
- ...if I do end up replacing the pump (which seems likely), any recommendation for a good alternative?
Thanks in advance for any advice or insights.

Also went for a "used - very good" option for almost half price. Fingers crossed.

I'm not getting the immediate shut off that you mention. The pump continues to run for maybe ten seconds to build up pressure. It might have something to do with the by-pass adjustment. Did you make any changes there?
Looking over the parts lists, the only physical differences between the pumps seems to be the Pump Head and the Pressure Switch. The 4008 requires a 10 amp fuse compared to the 4028's 7.5 amp. I'm thinking the only reason is that the additional water pressure of the 4008 puts more load on the motor. I'd be curious to know what the difference is in the Pump Head, but not enough to pull them apart to find out. They look identical from the outside.
