Pump Sentry 822 vs 1622: Avoid The #1 Compatibility Mistake

So you’ve finally decided that you want a (new) battery backup system for your sump pump, but now you’re deciding whether you should buy the Pump Sentry 822PS or the 1622PS.

Confusing isn’t it?

The chart below will make everything clear.

These things aren’t cheap so you want to make sure you get the right one from the start. Moreover, sending such a heavy item back is a hassle I don’t want you to go through.

I’m here to help you buy one of these backup options with the confidence that it is right for your existing sump pump. That is, you’re going to find out if you can indeed buy the cheaper 822 instead of the pricier 1622, or not.

First, I want you to understand one thing:

The #1 mistake people make

You see, the single biggest mistake people make when it comes to buying a Pump Sentry, is that they buy the model 822 while their existing sump pump requires more running amps than the 822 can maintain. 

The Pump Sentry 822PS is compatible with sump pumps that do not exceed a running Ampère rate of 9

Conversely, the Pump Sentry 1622PS is compatible with sump pumps that do not exceed 14A.

In short: 

People often own a sump pump that is simply too powerful to be powered by the 822. Those people need to get the 1622 instead. 

So how do you know the running amps of your sump pump?

This is where you need to start to sift through the specifications.

Fortunately for you, I’ve done all the work.

Scroll down below to the brand of your sump pump and find the model that you own. Right next to it you’ll see how many running ampere it requires, and whether you should therefore get the Pump Sentry 822PS, or the 1622PS after all.

Easy right?

Is The 822PS Compatible With Your Sump Pump, Or The 1622PS?

Below, I’ve composed a list for you of innumerous popular sump pumps. For each of them, I’ve collected the running amps of that particular sump pump, and have checked that metric for its compatibility with the Pump Sentry 822 and 1622. 

Just so that you don’t have to.

So scroll down below to find your sump pump or press control + F and type in the name or brand of your sump pump. Right next to it you will find whether you can get away with buying the pump sentry 822, or whether you’ll have to buy the more expensive 1622 instead.

Lastly, I know I don’t need to tell you that you should read the manual before installation and make sure that the device is properly grounded.. But I just did anyway. Safety first. I’d like you to come back.

Be safe and enjoy your new battery backup system!

Couldn’t find your sump pump?

I’m sorry to hear that. We try to keep this list as complete as possible and would love to hear which one we missed. 

In the meantime, I urge you to find the manual of your sump pump, as the ampère requirements should be listed there. If you’ve lost it, navigate to the website of the manufacturer and you should be able to find it there. 

Other differences between the 822PS and the 1622PS

Apart from the difference in running amps capacity, there’s one other specification that sets the 1622 apart from the 822.

The 1622PS has a 42A start current capacity, while the 822PS has 25A start current capacity. That means that during the first three seconds of the sump pump being turned on, the Sentry can feed it more energy to get the motor started. Heavy duty sump pumps may need the 1622PS because of the higher start current capacity.

Justification and disclaimer

This article is the product of hours upon hours of extensive research into over a hundred sump pumps. I believe all data to be correct but do not guarantee it. Information is provided as is. Read the manual carefully and make sure you ground the device properly. Hire an electrician if you’re unsure.

Sump pumps require more power on startup than once they’re running. Consequently, I’ve attempted to aggregate data about the starting amps requirement of all different sump pumps. Precise data about the required starting amps of sump pumps, however, seems to be incredibly hard to find (if available at all). This leads me to believe that this is not a frequent cause of trouble with compatibility, especially in comparison with the running amps. Moreover, SEC America, the producer of the Pump Sentry, writes on its website: “To determine compatibility with pump: User should verify that steady state pump current does not exceed 9A [ editor: / 14A]” without mention of the start amps. Again, I interpret this as running amps being the determining factor in compatibility between sump pumps and the Pump Sentry. Therefore, the compatibility chart only takes the running amps as a determining factor for compatibility.
