Does the back up pump sit higher than the pimary pump?

If the primary pump fails but the home still has power, will the backup pump use the home power or battery?

Thinking of a case where I might be on vacation and the primary pump fails. If the backup only works on battery then it could be long dead before I return home.

Will this pump work in a 5 gallon bucket? That is what the plumber installed (and cemented the 5 gallon bucket to the ground so groundwater will not raise it as that is what caused my recent flooding). It seems to just fit the diameter requirements. What size "sump bucket" would you recommend for this pump?
Asked by: Andy
I think the unit is too tall to work in a 5

1/2 HP Big Combination Unit with Special Backup Sump Pump System is rated 4.1 out of 5 by 95.

The back-up battery pump kept working well. Luckily it was still under warranty and Home Depot handled my return.I had my plumber install the new unit and it is working fine. Hope it lasts longer than first one.

Rated 5 out of 5 by from Great sump pump! Our old sump pump (20+ years) failed when we got a lot of rain from the remnants of Hurricane Isaac, partially flooding our basement. I did a lot of research trying to find a quality combination primary and battery backup sump pump at a decent price, and I definitely found it! Home Depot had a very competitive price and got it to me very quickly. This was my first sump pump install, so it took me some time, but it was very easy. The only drawback was that I had to buy the battery and acid separately and pour the acid into the battery myself - a little nerve-wracking, but no problems. I thoroughly tested the system, and both the primary and battery backup pumps work perfectly.

Filling the battery was the only pain & area with any risk. Pump has worked great since install 3 weeks ago. Quiet, poweful. The only question will be longevity. This pump (for a lot more $) replaces a simple inexpensive pump that lasted 13 years.
