Zoeller 585 Aquanot® II Battery Backup Pedestal Sump Pump System (2160 GPH @ 10')

This Zoeller battery power backup unit is the best I've seen. Be sure to get a good gel (sealed) battery to go with it, don't get a "wet" battery.

If you really want to have an extra layer of protection, get the # 007861 dual-battery kit and double the time you can run on battery power.

This pump worked so well the last 15 years, I replaced it with the same model. I am diligent about maintenance and replacement and this is the best pick for me. I tested this pump every month and cycled it 2 or 3 times and it never disappointed me. The time it kicked in when the water was overcoming the regular pump, it did fantastic. That was the biggest flood in over 100 years and those two pumps did fantastic.

I have a finished basement and after my main pump was overwhelmed by all the water from the thawing ice and snow, I knew I needed to get a back-up pump and I was thinking of getting a back-up generator in case of a power outage. My plumber friend recommended this as a solution. Installation was very easy and since I have a small pit, this fit right next to my primary pump. I test it each month and it's way more powerful than my primary. I only wish I could move the float further down. You can tell it's very durable and built to last. Best thing about having the battery back-up pump is I don't have to worry so much during a big rain event when I'm not at home, I know I'm covered.

My old one of 15 yrs went south, wanted to stay with the same so bought new. If you cycle your back up pump a couple times a month you will get the most life out of your battery backup pumps!!!

When my regular pump was getting very hot after several inches of rain fell, I unplugged the regular pump and let the backup work for a while. It did just fine. We will see how long it will last although rarely runs you would think it would last forever. My first one lasted 10 years. I got advise to run it every month or two to keep seals moist. I will sure do that.

We installed this system in our home about 6 years ago and it saved the basement from flooding. We had forgotten that we left the alarm in silence mode and one day we noticed the unit running while down in the basement. Upon checking the main sump we found that it had failed and the backup was acting as the primary pump. We weren't sure how long it had been doing this, but it performed fine until we replaced the main pump. Now we make sure the alarm switch is not on silence so we can find a problem sooner next time. Would buy this unit again.

Best main/backup pump in the business. I've always use this brand and they are reliable.

Thanks, everything went well and service was great.

The Zoeller 585 Aquanot is the best available battery backup sump pump system available and I would never buy any other system than this one. We recently replaced ours as the first one was finally showing signs of wear after giving us excellent and faithful service for over sixteen, yes 16 years. It is an awesome and outstanding system.

This pump is the best pump one can get for a back up system. Very easy to install.
