Whether you’re a homeowner or a landlord, if you need a sump pump system for your single family home, you’re also going to need a backup sump pump. If you choose a battery-based backup system, which is the most common approach, it’s up to you whether to simply add on a DC sump pump or whether to buy a combination AC/DC sump pump system from the start. If you’ve got a great AC sump pump already installed (e.g., an exceptional unit like the Zoeller M267), it makes sense to just get a DC pump. However, unless you’re completely satisfied with your AC pump, it’s typically a better idea to buy a combination AC/DC system from the get-go. When you do, you won’t forget to buy the DC component later on, procrastinate on the purchase, or back out and rationalize going without one because of how much you’d need to spend. Presuming you’re taking the proactive approach and buying a combination system, which one is worth getting?
On a small budget, it’s worth considering the Wayne WSS30V. But if you can spend a bit more, there are a number of good choices at the $500 mark, including the Wayne WSSM40V, our favorite combination system, the Zoeller 507-0008, the Zoeller 508-0006, and today’s model, the Zoeller 508-0007 Aquanot 508 ProPak 98 Preassembled Sump Pump System. As with the 508, it features the Zoeller 508-0005 Aquanot DC pump, but instead of the M53, it uses the Zoeller M98 for its AC sump pump, which makes it the fastest AC pump you can get in a pre-assembled combined package. We’ve had concerns with the M98’s reliability in the past, but Zoeller appears to have worked out the kinks when pairing it with the 508, making the 508-0007 a good choice for homeowners and landlords. You can read our full review below, but if you’re wondering whether it’s worth buying, we believe so, and you can buy it here.
Key Features of the Zoeller 508-0007 Sump Pump (60 Second Summary)
The Zoeller 508-0007 is a pre-assembled combination AC/DC submersible sump pump. The AC pump is a Zoeller M98 while the backup pump is a DC-powered Model 508 Aquanot. The primary pump features a 1/2 HP 115V motor while the backup pump features a 12V motor. The main pump’s maximum flow rate is 4,320 gallons per hour (2,350 gallons per hour in the backup). Zoeller includes a 3 year limited warranty. It is 12″ long, 12″ wide, and 20″ tall.
The Zoeller 508-0007 draws 5-10 amps and uses a battery backup. No battery is included and you will need to buy a 27, 29, or 31-size deep cycle battery. The reserve capacity must be at least 175 minutes and must not be larger than 13″ long, 7.5″ wide, and 9.5″ tall in order to fit the plastic battery case. Additional batteries may be connected via an additional case and hookup wire. Examples of deep cycle batteries we’ve reviewed with full compatibility include the Zoeller AGM, the MK-E27-SLD-G, and the Wayne AGM WSB1275.
The power cord is 8 feet long and the system weighs just under 58 pounds. Although it can pump up to 4,320 gallons per hour at 0 feet, it drops to 3,660 gph at 10 feet, 2,700 gph at 15 feet, and 1,500 gph at 20 feet with shut-off occurring at 23 feet.The backup pump maxes out at 2,340 GPH at zero feet, 1,800 GPH at 10 feet, 1,200 GPH at 15 feet, and 360 GPH at 20 feet, with shut-off at 22 feet.
The working temperature spans 40 to 120 degrees Fahrenheit. You’ll need a sump pump pit at least 18″ in diameter and at least 24″ deep. You can often squeeze it into a 16″ pit, but if you try to use a smaller diameter basin you’ll need to change the location of the outlet pipe.
How Does the Zoeller 508-0007 Compare to the Wayne WSSM40V Sump Pump and Zoeller 508-0006?
The biggest differences between the Zoeller 508-0007 and the Wayne WSSM40V involve the backup pump’s sophistication and the primary and secondary pump water removal speeds. The Wayne comes with a smart backup pump capable of calling up to 5 numbers under a variety of conditions (high water, power outages, low batteries, and more); the Wayne backup pump also runs monthly self tests in a range of areas to ensure consistent functionality.
When it comes to speed, the AC pump in the Zoeller is slightly faster than the AC pump in the Wayne while the Wayne’s DC pump is significantly faster than that in the Zoeller. We’d rate both systems as about equal in reliability. Compared to the Zoeller 508-0006, the 508-0007 is much faster, but the 508-0006 is more reliable due to the M53 main pump, which we see as a more reliable pump than the M98 in the 508-0007. Compared to the 507-0008, the 508-0007 has a much faster AC pump, a faster DC pump, and a more fully featured DC pump.
Our Short and Long Term Experiences Installing and Using the Zoeller 508-0007 Sump Pump
Installation is straightforward even if you aren’t a professional plumber. The main thing to remember is to cut your PVC pipe to make sure it fits in the sump pump pit. You’ll also want to remember to plug in a battery and plug in the battery charger (as well as the AC line for the main pump, of course) so you’ll be able to automatically recharge the battery.
Noise-wise, you can expect similar levels to the Zoeller 508-0006 and Wayne WSSM40V. The M98 is a touch louder when running at full speed, but this also means it should run far less frequently. Regarding long-term reliability, we’ll be honest and state that we’ve heard some horror stories regarding the M98 component when installed by itself, and although we hear far fewer bad reports when it’s paired with the M508 in the 508-0007 package, we don’t think this package is as reliable as the 508-0006, and we’d conservatively give it a 7-14 year lifespan estimate.
Troubleshooting and Installation Tips to Get Your Zoeller 508-0007 Working Sooner
The biggest thing to remember when installing your Zoeller 508-0007 is that you’ll need a 12 volt deep cycle battery installed in the M508’s battery chamber. We recommend batteries like the the Zoeller AGM, the MK-E27-SLD-G, and the Wayne AGM WSB1275, as we’ve confirmed their compatibility with the Zoeller, as well as with every other combination and DC-only system we’ve reviewed so far. In general, you’ll need a size 27, 29, or 31 battery with at least 175 minutes of reserve capacity. You’ll be able to expect up to 7.5 hours of continuous operation of the backup pump, which will give you a real world window of around 4 days of intermittent operation.This should be plenty of time to get back to the pump and install a generator or swap in a new battery if you’re somehow still without power (hopefully not!).
Zoeller 508-0007 Sump Pump’s Pros, Cons, and Value Comparison
Overall, we generally like the Zoeller 508-0007. It’s the fastest AC/DC combination pump on the market, with a main pump that’s actually faster than that in the Wayne WSSM40V, although the Wayne has the faster backup pump. It doesn’t feature the smart components of the Wayne, but we can wholeheartedly vouch for the M508 backup pump; the potential weak link is the M98 main pump. While the majority provide years of trouble-free service, there are some out there that are poorly soldered and can prematurely fail. We’d recommend choosing the Wayne if your priorities are the communicative and self-monitoring features it includes. If your top priority is reliability, we’d recommend the Zoeller 508-0006. Finally, if your top priority is speed, you’ll want the Zoeller 508-0007, as it has the highest top speed of the three in the main pump. You’ll have a good combination system in either case. Between the Zoeller 508-0007, 508-0006, and 507-0008, we’d recommend the 508-0006 or 508-0007 due to the greater functionality in the backup pump.
