Overview
A basement with an existing sump pit is where the Zoeller 508-0005 does its work, running on DC battery power when household power fails. The pump has a built-in check valve and a quick disconnect discharge, and its seal pocket and cooling plate are aluminum.
A noncorrosive pump body with an integrated check valve makes it a self-contained backup unit that can be added beside a primary pump. The limitation is that it runs only from a battery-fed DC supply, and the listing never says whether a battery or charger comes with it.
Who it's for
Homeowners who have lost power during storms and already have a working primary pump can add this as the second line of defense. A buyer who needs a pump that runs on household power alone, or who wants everything supplied in one kit, should look at a complete system instead.
Pros and cons
- Integrated check valve
- Quick disconnect discharge
- Noncorrosive pump construction
- Hand built and fully tested in the USA
- Battery not listed as included
- Maximum lift height not listed
- Warranty text is cut off in the listing
Performance notes
The DC motor draws from a battery, so running time during an outage depends on battery capacity and how often the pit refills. The check valve stops water from flowing back into the pit once the pump shuts off. The aluminum cooling plate carries heat away from the seal area, which protects the pump during long runs.

Frequently asked questions
Is the Zoeller 508-0005 a complete sump pump system?
No. The listing item type is plumbing replacement parts and the title calls it a battery back-up system, so it is the backup unit, not a full primary pump kit.
Does the 508-0005 come with a battery?
The listing does not mention a battery and the included components line reads product only. Confirm with the seller before ordering.
How long is the warranty on the Zoeller 508-0005?
The listing gives 12 months from installation or 18 months from manufacture, extended to 36 months with the purchase of an Aquanot product. The text is cut off after that.
What does the check valve do?
The listing says the pump has an integrated check valve. It is there to stop water flowing back into the pit after the pump stops.
