Are they junk?
I'm using a 3/4Hp, 110GPM model to drain an 18 gallon tank used to recover water from an engine dyno. The pump sits for months at a time w/o being used. When we go to use it, it just hums but won't spin. If I take the pump out, spin the impeller with my hand it will then work. The first time this happened the tank was left empty for months, so I figured rust on the impeller may have jammed it. After that I started leaving the pump fully submerged in water, but the same thing happend. The water is clean city water.
Has anyone else had this problem? Is a better quality pump the solution? Or is it just sitting too long w/o use?
Thanks,
Josh
