what difference between sump pump M53 and M57?
1531200
M57 features all cast iron parts while the M53 has a plastic base and engineered plastic impeller
1531201
One has metal base plate the other is plastic, not sure which is which. The more expensive one has the metal.
1531202
On the M57 the bottom part of the pump and the impeller is all metal, on the M53 its high impact plastic.

If the sump area is small and your discharge is at a somewhat high elevation, the water will flow back in and cause the pump to continue to restart. I would suggest you install an inline check valve just after the pump discharge.

The Zoeller pumps are very reliable... But you might be risking a wet basement if it is in fact 20 yrs old. The only part that you need to keep an eye on is the switch. After 9 years, mine gave out. I have 2 pumps in the sump and the other took over. It is on a raised platform (approx. 2.5 inches) and only kicks in if unit 1 fails. As for the hole, it is supposed to be there. It is my understanding it needs to be there to prevent an airlock in the pump.it also keeps the gunk from forming around the bottom of the basin.

The only difference between the N53S and the N53SV models is the processor, the boards are the same. You use the workhorse 120 Watt power supply and this knock out board is designed for it, it goes in pretty easy. These knock out boards burn out easy if people try to use a cheaper 90 Watt power supply in stead of getting the correct one.

I don't know the difference. If one model is newer than the other, go with the newer model. Zoeller pumps are high quality. I have never had trouble with any Zoeller pump.

Besides the obvious - 520 is 520 watts, 620 is 620 watts - the M series has modular connectors, while the S series does not. Most people don't need the large number of included connectors, so using a modular supply results in less clutter. SeaSonic is a quality power supply vendor, so both are good quality. Your primary decision is whether you want to pay a few extra dollars for the modular connectors. As far as Haswell ready, that's not an issue - they all are (including those from other vendors.) You need to identify your total power requirements; your choice of wattage will derive from that.

92853 has the pour out spout. 92856 is the marine version to be used in boats with pumps and is not interchangeable with pour-out spout

That depends on the current draw of your sump pump. Most seem to be under 10A and so should be okay with the 13A this cord can offer. Do be sure though that your generator is designed to handle starting a motor -- to do so requires a sudden rush of power. Once the motor is up to speed, it goes back to a steady so the cord should be okay unless the pump cycles so frequently the cord has time to heat up with the more frequent starting overloads.

It has a Water Detection Sensor that you can add. It has a phone cord and phone cord jack in the unit that it plugs into. Not sure if your sump pump switch would be compatible. But phone cord is cheap and you can run additional cord if needed from the unit to the sump and use the sensor. That way it wouldn't alarm every time your sump kicked in, but rather would only alarm if the sump ran over onto the floor. The sensor is worth the extra $ if it doesn't come with the unit you buy. I have one that has been in service for 3 or 4 years and still works flawlessly. I will say this unit is more dependable then some others on the market. Beware.

it is hard to say with out seeing what you are useing it for . on a sump pump you tie wrap it to the pipe or pump so it will hang down as the water rises the float will turn up and the pump will start and lower the water level

You don't want 550p MSD model, its the the marine version without outpour spout. you want the 550e model for camping with the outpour spout that is how you empty it. There is a lever in the back that slides and separate the top tank from the waste tank and the outpour spout turn outward to empty.

The model I purchased, Zoeller 57-0001 M57 Basement High Capacity Sump Pump, is for a 1 1/2 inch discharge, so I would "search" on Amazon for a "Sump Pump 2 inch Discharge" and you should be able to find what you are looking for.

Different model numbers are for gallons per hour the pump is capable of pumping
