Pump not pulling any water

[rqbanerjee]

Thanks a lot guys! It seems that their is a blockage in the line. I disconnected the pump and used the garden hose to force water down the line backward to the hopper. Tied it up with rags and everything, and the water squirted out at me. So it must be clogged.


I'll pick up that "Drain Jet" gadget tonight. Is it safe to use a plumbing snake if water pressure can't blow out the blockage? I'd hate to puncture the lines which are buried beneath feet of concrete.

Thanks a lot!
