While disinfecting my h2o system, I thought I would check out the pump. I disconnected from shore power, started the generator, and turned on the pump. Nothing. Checked the pump-it was humming, but no h2o. I turned the switch from city h2o to tank, still no h2o. Thinking maybe it took a while to prime, I left it on for about 5 minutes - nothing. Any suggestions?
