A Backup Plan
The purpose of a backup sump pump system is to replace or supplement the pumping capacity of the primary pump during one or more of these common occurrences.
Power Failure – When power goes out, your primary pump won’t work (unless you have a emergency backup generator).
Mechanical Failure – Pumps burn out, switches get stuck and these things usually happen when you need your sump pump the most.
Weather Events – Flash flood type rains or excessive snow melt can put more water into your sump pit then your pump is able to handle.
People often underestimate what can really happen to a basement when a flood occurs.
Here’s an excellent video example! (Make sure your volume is on, you can hear the sloshing)
Understanding Our Lingo
GPH @ 10’
It may seem like code, but it only means “Gallons Per Hour” at a given height.
We display the GPH for backup sump pumps at 10 feet for a reason.
In most cases, your backup pump is going to have to lift the water around 10 feet until it’s able to discharge.
Primary pumps list their GPH at multiple levels because their applications can vary. |
STEP #1 Check Primary Pump
All pumps have a data plate on them.

Most of the time it is located on the pump or on the cord. Simply find your pump’s HP, and then move on to the next step.
STEP #2 Monitor Pump Performance
Simply pay attention to how often your pump runs.

Try to do this during a period of time when it’s raining outside.
STEP #3 Use The Chart
Now that you know the HP of your primary pump and the frequency it runs, you're almost there. The output ratings on the chart can give you a pretty good idea of what Backup Sump Pump System would suit your needs.
The Next Step
To make this process simple, the Backup Sump Pump Systems are split into two categories.
Standard Output- If your system requirements are less than 2000 GPH.
High Output- If your system requirements are greater than 2000 GPH.
