If you’re interested in keeping your basement dry, you’ll want to make sure you buy a reliable sump pump. Although it’s tempting to pick up the cheapest sump pump you find at the nearest box store, we recommend being a bit more choosy, because replacing one after a quick failure is frustrating, expensive, and frankly a waste of valuable time. When it comes to lifetime sump pups, we always recommend the Zoeller M267; it pumps more water than nearly any other sump pump you can buy and it’ll work for 10-20 years, but it’ll also cost you around $300. If you have a smaller budget, for under $200, two solid choices include the Wayne CDU980E and the Zoeller M53; between these two, we prefer the Zoeller due to its more solid construction and greater long term reliability. However, if you can spend a bit more, the Zoeller 57-0001 M57 Basement High Capacity Sump Pump is an even better choice. It’s basically the M53 with full cast iron construction, including with a cast iron impeller instead of the plastic impeller on the M53. If you’re looking for the most durable sump pump for $150, this is the one you want. Read on for more details why.
Key Features of the Zoeller M57 Sump Pump (60 Second Summary)
The Zoeller M57 sump pump is a submersible sump pump featuring a 3/10 (roughly 1/3) horsepower motor, a 2,580 gallon per hour maximum water flow rate, and a 1 year warranty from date of purchase or 18 month warranty from the date of manufacture. It’s 7.8 inches tall, 10.5 inches wide, and 10.5 inches deep. The maximum pumping height is 19.25 feet and the switch-on/switch-off heights are 3 inches and 7-1/4 inches respectively; the pump switch is vertical. It’ll use between 4.8 and 9.7 amps while running on 115 volts. No battery backup is included. We weighed it at 21 pounds and the power cord is 9 feet long. While the max discharge flow rate is 2,580 gph at 0 feet, this drops at 10 feet to 2,040 gph, at 15 feet to 1,140 gph, and is inoperative by 20 feet. It has a working temperature range of 40-130 degrees Fahrenheit. The M57 is self-priming and is housed fully in cast iron. The impeller is also cast iron. The discharge size is 1-1/2″ NPT. It’s designed to be used with sump pits at least 15 inches in diameter.
How Does the Zoeller M57 Compare to the Zoeller M53, Wayne CDU980E, and Zoeller M267 Sump Pumps?
The main differences between the M57 and the M53 are in construction of external and internal components, which lead to differences in durability and expected lifespans of each sump pump. We’d expect the M57 to last between 8 and 16 years due to the upgraded impeller; it’s plastic on the M53 and cast iron on the M57. Similarly, while the base on the M53 is thermoplastic, which is a fancy word for hardened plastic, the switch case, motor, and pump housing of the M57 are cast iron, adding to its longevity.
In comparison, the Wayne CDU980E has a much faster max flow rate (4,600 gph vs 2,580 in the M57/M53). However, because the M57 is built to tougher standards, it’s less likely to break down over time and it’s also less likely to become stuck or clogged due to contaminants and debris in your sump basin. The impeller is rated for shredding up to 1/2″ (12mm) spherical solids. What this means is that while we’d expect 8-16 years of life for the M57 and 7-15 from the M53, we’d only expect 4-8 from the CDU980E; if you don’t like replacing your sump pumps often, you’ll want to make note of this.
However, if your goal is to maximize your sump pump lifespan and efficiency (whether for financial reasons, environmental reasons, or simply because you really hate calling out plumbers or spending time in your sump pit), you’ll want the M267. The M57, M53, and CDU980E don’t come close to it. The M267 can pump far more water (its top flow rate is a mind-boggling 7,680 gallons per hour), it can handle up to 2″ solids, and you can get up to 20 years (or more) of useful life. If you want the most durable sump pump on the market, you want the M267.
Our Short and Long Term Experiences Installing and Using the Zoeller M57 Sump Pump
We had no problems installing the M57, and we’d expect this to be the case for the average homeowner. You simply connect a 1-1/2″ male threaded fitting to your sump discharge pipe. Afterward, you insert the pump in your sump pit, make sure it’s level and that your float doesn’t touch anything in the pit, and plug the pump in. Don’t forget to install a check valve (we suggest a silent one like the Brady check valve) and drill a 3/16
relief hole as noted in the instruction sheet.
Once we’d installed it, we were pleasantly surprised at how quiet the M57 was. In retrospect, it shouldn’t have surprised us, since the M57 is basically the M53 with slightly upgraded components, and the M53 was already one of the quietest budget sump pumps we’d reviewed. However, it’s worth repeating that it’s basically inaudible from more than a few feet away, and it stays that way for years; we’d estimate somewhere between 8 and 16 years of life for most owners.
Troubleshooting and Installation Tips to Get Your Zoeller M57 Working Sooner
Once your Zoeller M57 is in place, to keep it working for many years, it’s a good idea to check the action of the float switch every now and then, especially if you have a relatively dry sump basin. You’ll want to do this to ensure the switch doesn’t dry out and get stuck over time; if this occurs, it won’t activate your sump pump when water starts rising, which won’t lead to good things.
Even though we expect the M57 to be reliable, we always recommend buying a DC backup sump pump (or a water-powered backup) to support it (or really, any AC sump pump). If you can spare several hundred dollars, there isn’t a better DC-based backup pump than the Wayne WSM3300. However, on a much smaller budget, the Wayne ESP25 is a good alternative; the most important thing is to have some kind of backup pump in place to keep your basement from flooding when you lose power.
While it’s tempting to simply buy the standard Zoeller check valve, we’d highly recommend putting a few dollars more into a silent check valve. This will get rid of the “thunk!” sound that accompanies normal hammer check valves, and will make your M57 effectively silent. We recommend the Brady check valve as a cheap and reliable option.
Finally, a cheap separate water alarm is good insurance and common sense in our books. It doesn’t have to be top of the line; the Basement Watchdog will do. You just want to make sure you set it up in your sump pit above your float switch (preferably your backup DC sump pump float switch). Your water alarm will then go off if something goes wrong with your M57 (i.e., a power outage), or if your backup sump pump can’t keep up with the water or doesn’t activate for whatever reason. If you then hear the water alarm sensor, you’ll know your sump pumps (and basement) need you.
Zoeller M57 Sump Pump Pros, Cons, and Value Comparison
In conclusion, for $150, the Zoeller M57 is a better sump pump than pretty much any other budget sump pump out there. Unless you need the higher flow rates of the Wayne CDU980E, the M57 will be a better choice due to its greater longevity and ability to handle contaminated or debris-filled water. However, if you want a much faster and more durable pump, we recommend the Zoeller M267 if you have any kind of choice.
