This warranty can be extended to 3 years if the user purchases an Aquanot battery along with this combination sump pump.

Zoeller 508-0005 Testimonials

This pump functions exceptionally well and carries out its job seamlessly. Installation was straightforward as it has worked perfectly with its battery for about 2 years. The only minor issue I have has to be with the faint text displayed on the LCD screen. The charger still functions well but I cannot confirm its status on the LCD screen. I cannot just replace the LCD as the screen is combined with the charger.

The design of this pump is quite efficient and its noise level is very low. The LCD screen alerts one in case of A/C failure and it displays run time. I bought a Zoeller Mighty Mate some years back and it is quite compatible with this backup sump pump. Installation was smooth as I did it myself without any hiccups. I am still monitoring it ahead of serious rain but for now, it has proven to be quite efficient and functional.

  • It offers consistency and trouble-free service for as long as 10-15 years.
  • It is hand built in the United States of America and 100% tested against errors.

  • It is non-corrosive and has a quick disconnect discharge.
  • It has an LCD screen which displays useful data such as the voltage of battery amongst other essentials.

  • This 11/4 inch sump doesn’t come with an adapter making it impossible to install the anti-siphon valve.
