Q: can this system be used with AGM batteries? by Don G from Illinois on April 21, 2016
A: Yes! This system will work with wet cell or maintenance free AGM batteries. I recommend deep cycle 12V rated at a minimum 100ah or 175 reserve minutes. Please note that the Zoeller 508 Battery Backup System does include a 1 year manufacturer warranty. If you purchase the Zoeller 10-1450 - Aquanot 12V Deep Cycle 72AH AGM Battery or the Zoeller 10-0761 - Aquanot 12V Deep Cycle 83AH Wet Battery at time of purchase, that warranty is extended by 2 years to a THREE year manufacturer warranty. If you have any other questions, please let me know. by Jim, Product Expert
Q: will the Zoeller 508 run on AC power if necessary? by Scott B from Illinois on January 19, 2016
A: No, this system only operates on 12V DC power regardless if you have AC power available. by Jim, Product Expert
Q: I have no experience with battery back-up systems but I'm considering this system for purchase. It does not include a battery. What type and size battery is optimally recommended for this system? by Kevin from New York on April 08, 2015
A: The Zoeller 508 Battery Backup Sump Pump System battery box will accept all group size 27, 29 and 31 batteries. This includes wet cell and maintenance free batteries. The larger the battery AH (Amp Hour) or CCA (Cold Cranking Amps), the longer runtime your system will realize. That said, the system comes with a ONE year warranty. IF you purchase a Zoeller Aquanot WET CELL BATTERY or MAINTENANCE FREE BATTERY at time of purchase, that system warranty will be increased to THREE years.
Q: Does the Zoeller Aquanot 508 have to be installed as shown in the picture (integrated with the primary) or can it be installed with separate piping and check valve next to and above the primary? Thanks in advance! by Chris from Indiana on February 07, 2015
A: It can be installed separately. A check valve is already integrated on the discharge of the 508 pump, so no other check valve is needed. by Jim, Product Expert
Q: Hello! What is the minimum amount of clearance needed to install the Zoeller 508 - Aquanot system? I have an older house with a relatively small sump basin. Thanks! by Dave from Michigan on November 27, 2014
A: Minimum pit size requirements: 18" diameter X 24" deep. For 18" x 22" applications, consult Zoeller at 800-928-7867. by Jim, Product Expert
The pump's ability to move water quickly at a 9' lift was surprising considering its power consumption. The battery charger/monitor gets the job done and maintains a good float level to maintain the battery's health. Build quality seems to be top notch!
Pros:I'd Buy It Again, High Quality, Quiet, Exceeded Expectations
Cons:Expensive

"Received the order quickly even with basic (non premium) shipping."
(Disclosure: I have owned multiple Zoeller AC pumps for years and have liked them very much. This is the first battery backup Zoeller for me however. )
Installation was not a snap. The horizontal discharge when attached via the recommended PVC tee fitting to my existing AC pump made the assembly too wide to fit in my (standard size) sump pit. I had to independently plumb the AC and DC pumps, place them to fit in the pit, and then plumb them together using a 45 elbow and a wye fitting. Not the end of the world, but definitely a time eater.
The inclusion of in line check valves for both pumps was an unexpected side benefit.
The battery charger displays batt voltage and charging current continuously. When I first installed the unit using a new maintenance free marine battery, it started out charging the full 10 Amps, went down to 3 after a while (when the voltage was at 14.2 v), and at that point I stopped watching. I came back several hours later and the voltage was 13.1 v with no charge current. I was somewhat surprised as I expected some charge current of 25, 50, or 100 ma to top off the battery. The manual speaks somewhat cryptically of a charging hysterisis, so the 0 charge current may be proper operation, but at this point, I'm not sure if it's proper or I have a charger malfunction. With a little better manual, this might have been explained better.
The movement on the float switch is less than 2 inches, which means the pump runs often for short duration. Not inherently bad, but again, a little unexpected.
None of these points are killers, just a little concerning. With any pump, the ultimate tests are its pumping and reliability. Based on my previous Zoeller experience, I expect both to be great, but only time will tell.

Was amazed by how quick the pump was delivered. I wanted to place a battery a little further away than the pump cables allowed but Zoeller informed me that adding additional wiring would void the warranty. Like other reviewers, I was concerned about the weight of the pump so I built a little table using a 6" NDS grate and 6" pvc for it to sit on. I wasn't sure the pump ran the first time I tried it because it was so quiet. The only feature I would have liked to have seen would have been an elapsed timer. Very happy with the package and it was easy to install.

"I've ordered before from Sump Pumps Direct and again had great service and quick shipping."
Very easy installation, and a high quality pump. Even with its high quality, I found the price of the unit to be a bit high.

The Real Deal
Good value, easy to install. I tested and it's a legit 30 gallons a minute at a 10 ft lead. Had the basement watchdog big dog rated at 36-38 and I tested it at 16 gallons which I promptly returned. Plus it's very quiet, much quieter than the big dog. Made in the USA so that's a plus too nothing cheap on this model and the charger is 10 amps so this will charge your battery quickly. Just released so it may be the first one using peak flow pumps input and design (they bought them this year), and based on the performance I had it probably is. If you are on a budget and want to keep your basement dry buy this one!

Keep Your Battery In Mind.
This product installed well and seems to have all the necessary features. I like the quality of the charger -- good indicator lights.
In building a backup system, people need to think about the battery. All lead acid batteries do deteriorate and need to be replaced every few years. 3 years seems to be a safe number.
No matter how little you use your backup system and how consistently it is charged, the battery will fail completely in a few years.

Great Quality, Fast, Friendly & Knowledgable Service
Needed a back up pump when power fails from storms. Water surge is substantial. The old backup worked but did not pump enough water to counteract surge. Pump pit is small and crowded. Pumps Direct knew what to use and how to install. Works great!
Pros:Features, Easy To Use, Quiet, Price

Awesome Product/easy To Install
Bought this to add to my existing pump. Was super easy to install, pulled up my existing pump, cut the pipe, inserted the tee and hooked up the Zoeller pump and dropped it back in the sump.
Did it all while the sump was still filing due to our record rainfall. Hooked it up to the battery and tested it in various "failure modes": main pump failure with power complete power failure- works like a champ. Great peace of mind. Highly recommend.
