In five years I’ve replaced two pumps and my third is acting up already. The pit is small in diameter so I can’t use a typical submersible or pedestal pump. Instead I’ve been using a Drymaster Pump Model CM-4. These pumps are fairly expensive, around 400 bucks for a rebuilt one.
Occasional I notice water at the floor drains, an indication the pump is not kicking on. When I walk over to the pump it smells hot and is hot to the touch. If I tap the side of the motor with a wrench it grinds and kicks on. I’ve taken the pump apart but I don’t see any burning or melted parts.
The pump does not run continually so I know it’s not form overusage. I know the pump should not have to be replaced in under ten years but they are only lasting about a year and a half.
Any ideas what’s causing my pump to seize up so fast?
