Chugger Pump Problem....

[J-Pizzel]

Have a single tier stand with two pumps. Pump A first and pump B second. Pump B stopped turning on although you can see the fan turn for half a second the motor doesn't run. Took the head off of pump B and the motor works. Put the head back on and it doesn't turn on again. Moved the head over to pump A and that motor won't turn on with it as well.... ended up having to use the head from pump A to finish everything. But I can't figure out why neither motor will turn on with this single pump head. Any suggestions? As always, thanks in advance!

You probably have a chunk of something keeping the impeller from turning. Take the back plate off the head and turn the impeller by hand.

Thanks Bobby and great shop, products, and vids! We ended up taking that off and noticed some kind of black corrosion build up. It started running again, thanks!
