How old is your Ace in the Hole?

I had one freeze up on me and had to replace the motor.

You should exercise the pump on a regular basis. The "Ace in the Hole" will
have a "test" button on the battery case.

you could hook up your regular pump to the AITH discharge pipe and see if
there is a blockage.

Are you using an additional check valve in the AITH discharge pipe?

Could the check valve be in backwards?

The AITH is a pretty simple machine so a little detective work should
narrow it down. You could also talk to the local AITH distributor for
ideas. I've bought all of mine at Menards but there are others out there.

All,

I just bought a house with a redundant battery operated sump pump
installed (brand name is "Ace in the Hole"). I decided to test it out
by unplugging the main AC unit. The pump made noise like it was
running but didn't pump any water out. The date on the battery says
it is only 4 months old. I checked the battery water levels and they
were all ok.

Any ideas? Does it sound like a bad pump? I should mention it has
its own pipe running from the pit to the outside, so maybe the pipe is
plugged?

Thanks,
Dan
