Re: Bilge Pumps Won't Suck
Sorry to ask such a basic question, but are you sure that you did not wire it up backwards?
Try some systematic troubleshooting. So you have power, the impeller spins...check. Try it with the bilge pipe disconnected, of with a small length to check you are blowing not sucking - see if the water flows easily...basically test the pump/wiring. Perhaps put the pump in a bucket of water to test it.
If all the above shows a functioning pump, perhaps your bilge pipe is blocked. Try blowing down it!
