All,

When testing my battery powered backup sump pump a few weeks ago, I
noticed it wasn't pumping any water (it was making noise like it was
trying to). *I disconnected and then re-connected the pipe and it
seemed to start working again. *Now a few weeks later, I checked it
and had the same problem, and again it was resolved by disconnecting
and re-connecting the pipe.

The battery is only a couple years old and the water levels look fine.

Any idea what could be going on?

Thanks,
Dan
