  • 1-year limited warranty.

Build Quality and Operation

The best sump pump operates in what can only be described as less-than-ideal conditions. In many cases, they are in or underwater nearly all the time. As such even the slightest defect in build quality could lead to a tiny leak that could undermine the entire pump.

The M53’s cast iron construction and vacuum seal ensure that no moisture will penetrate the outer casing to cause trouble. The cast iron also allows heat from the 1/3 HP motor to dissipate through the housing, an important consideration for a hermetically sealed unit. The cast iron itself sports an epoxy coating that wards off corrosion.

The hearty 9’ power cord is adequate though most people we’ve talked to expressed a wish it was a bit longer and we can understand that. The longer the cord, the more setup options you have.

But that aside most other elements of the pump are thoughtfully designed and carefully constructed. The 1/3 HP, 1550 RPM motor is sufficient to handle whatever volume of water flows its way and even prolonged periods of continuous service won’t result in the unit overheating.

The M53 features auto on/off via a polypropylene float assembly and a waterproof 2-pole switch. The design of the unit’s impeller fins ensures clog-free operation and the incident-free passage of solid particles. A sturdy switch guard also ensures the unit can operate uninterrupted and if the guard ever needs to be replaced it’s typically a simple DIY project
