I previously had a Zoeller M53 pump for 9 years with absolutely no problems so when it came time to replace it that is the only one I wanted.

These Zoeller pumps are virtually bombproof. I have an M53 and M98 with battery backup protecting my basement. They run very reliably and are easy to service. However, you can't just plug them in and forget about them. Here are a few things I've learned over the years.

***IMPORTANT***

The key to keeping them running forever is some periodic service.

1) SWITCH : As many have found the hard way, it's unfortunate that the switch in this pump is the weak link in an otherwise bombproof product. Luckily, this plastic switch is very easily replaced with a screwdriver ($25-part # 004892 or 004705 - don't forget a rubber gasket). They seem to last 3-6 yrs depending on the conditions used - mine activate on average every 2-3 minutes, sometimes as frequently as every 20 sec during a heavy storm. The switches in my pumps last 3-4 yrs.

2) RUBBER FLOAT LEVER BOOT: The rubber boot/seal where the float lever enters the pump cap assembly will harden over time, providing just enough resistance for the lever not to activate the pump switch (very frustrating to find the pump submerged underwater, then the slightest movement triggers the motor) - keeping this lubricated with a bit of silicone grease will help prevent or solve this problem. (Make sure not to use a petroleum based grease.) When/if it fails, the cap assembly will need to be replaced ($30 - part #004703).

3) IMPELLER/CHECK VALVE : periodically remove the base of the pump (just remove several screws) to scrape/clear out any built up debris or buildup, clear the area by the exit pipe and make sure the check valve can operate properly.

4) FLOW HOLES - there are two small holes in the pump assembly by impeller and exit pipe. These will get clogged over time and can cause an unlikely 'airlock' situation where the impeller with turn freely within a pocket of air and not push any fluids. Keeping these holes clear with a nail will prevent this condition.

Zoeller M-53 Sump Pump

A house we are remodeling had a leaky basement. Heavy rains lasting a few days resulted in an inch or more of water in the basement. A real mess. We got bids from 6 basement waterproofing companies. Five companies said they installed Zoeller M-53s because they were the most reliable pump they were aware of, and angry customers with failed pumps were bad for business.

The company we hired did a great job, as the basement is now bone dry regardless of rainstorms. The M-53 is so quiet, that unless you are near the sump basin, you can't hear it run. It's only been a year since installation, so I can't rate pump longevity; but so far, it's worked just fine.

The M-53 turns on when the water level depth is 7", and shuts off when the water depth is 3".

The contractor installed a sump basin with TWO pumps: an M-53 and the Zoeller model 507 backup pump, which uses a 12-volt marine-battery. At a 5 feet head (from pump to water discharge), the M-53 pumps 43 gallons per minute, and the 507 does 23 GPM. A backup battery operated pump provides extra protection when the primary AC pump fails due to: storms, brownouts, the primary pump fails due to damage, mechanical malfunction or obstructions in the pit, or when the primary pump fails due to damage, mechanical malfunction or obstructions in the pit, or when the primary pump fails to keep up with excessive water due to rain or overloading. As far as I know, the 507 has never kicked-in, but it does eliminate worries about basement flooding.

The bottom assembly (containing the feet) is plastic on this pump, as is the impeller. Zoeller makes a better version, called the M-57, which is identical to this one, except the base is cast iron, as is the impeller.

This is a solidly-built pump that will last for many years. It's a tried and true design that hasn't changed in years. You can get parts for it at your local Zoeller dealer to repair the unit, if you are willing to do so. However, after several years of using it I can definietly say that the pump switch is the weak link. My first pump switch failed a year. A coworker who I recommended the pump to also had a switch fail after 2 years. The pump itself good, but the switch is junk. My recommendation would be to get a Zoeller pump without the integrated float switch, and run an external switch. That way you can easily replace the external float switch every couple of years.

Had this pump for four years in my house and eight years in my businesses ' it has never failed yet. Those people who give it bad reviews often don't have a clue to what a sump pump does, and the different types. Zoeller's M53 shares the same dimensions and is nearly identical to the M57. The M53 has a cast iron switch case, motor, and pump housing, a thermoplastic base, and an engineered plastic impeller with metal insert. Like the M57, it can pump 43 gallons (163L)/minute, passes half-inch solids, and shares a 1.5" discharge. Zoeller is the industry standard: don't let anyone tell you differently. It's the brand the professionals use and the plumbers recommend. If you need the extra casing weight and prefer a cast iron impeller, get the M57.

I have two Zoeller m53-D pumps installed. Twice now on one of them the switch has become stuck on and the pump runs continously. If I hadn't noticed this fairly quickly the motor would have run dry until it had overheatd and burned out. Works fine until this. Extreme safety issue.
