Power outages often happen during heavy rainfall and severe storms—exactly when your sump pump may be working hardest to protect your basement.
A battery backup system can help keep your existing sump pump operating when household electricity is interrupted. But choosing the right system is essential.
Two options available to Canadian homeowners are the Pump Sentry 822PS and Pump Sentry 1733.
Both provide backup electrical power, but they are designed for different pump requirements.
What is the difference between Pump Sentry 822PS and 1733?
The main difference is power capacity and pump compatibility.
The Pump Sentry 822PS is designed for compatible residential submersible sump pumps with relatively modest electrical requirements.
The Pump Sentry 1733 provides greater power capacity and can support compatible higher-demand sump pumps and certain sewage ejector applications.
Neither system replaces your existing pump. Instead, they provide backup electricity so a compatible pump can continue operating during an outage.
Pump Sentry 822PS vs. 1733: Comparison
| Feature | Pump Sentry 822PS | Pump Sentry 1733 |
|---|---|---|
| Primary application | Compatible submersible sump pumps | Compatible sump pumps and sewage ejector pumps |
| Continuous power rating | 1,200 watts | 1,800 watts |
| Maximum running current | 9 amps | 14 Amps |
| Starting current capacity | Up to 25 amps | Up to 45 amps |
| External battery | Required; sold separately | Required; sold separately |
| Backup function | Powers an existing pump | Powers an existing pump |
| Best suited for | Lower-demand compatible sump pumps | Higher-demand compatible pump applications |
Important: Electrical compatibility depends on the pump's actual running current, starting requirements and manufacturer specifications—not horsepower alone. Confirm current product ratings before purchasing.
When should you choose the Pump Sentry 822PS?
The Pump Sentry 822PS may be the right choice if you have an existing compatible submersible sump pump that operates within the model's electrical limits.
It is designed to provide backup power without requiring the installation of a separate secondary sump pump.
Before selecting the 822PS, confirm:
-
Your existing sump pump is a compatible submersible AC model.
-
Its running current does not exceed the manufacturer's specified limit.
-
Its starting current is within the system's supported capacity.
-
You have a suitable external deep-cycle battery.
The 822PS is not intended for every type of pump. Compatibility should always be checked before purchase.
When should you choose the Pump Sentry 1733?
The Pump Sentry 1733 is intended for compatible applications that require greater power capacity.
It may be appropriate for homeowners with higher-demand sump pumps or compatible sewage ejector pumps.
The 1733 offers higher continuous power and starting-current capacity than the 822PS, but that does not automatically make it the better choice for every home.
The correct model depends on the equipment you already own.
For sewage ejector applications in particular, confirm the pump's electrical specifications and the manufacturer's compatibility requirements before purchasing.
Do both Pump Sentry models need a battery?
Yes. Both models require a suitable external deep-cycle battery, which is purchased separately.
The battery stores the energy used during a power outage.
How long the pump continues running depends on factors such as:
-
Battery capacity and condition
-
Pump power consumption
-
Frequency and duration of pumping cycles
-
Water entering the sump pit during a storm
-
Overall system efficiency
A higher-capacity backup unit does not automatically provide longer runtime. The connected battery and pump's energy consumption are critical.
Can Pump Sentry replace a broken sump pump?
No.
Pump Sentry is a battery backup power system, not a secondary pump.
If your existing sump pump fails mechanically, supplying backup electricity will not make it operational again.
Homeowners concerned about both power outages and pump failure may need to consider a separate secondary pumping solution.
How to choose the right model for your home
Before purchasing either system, follow these steps:
-
Identify your existing sump pump's manufacturer and model number.
-
Check the pump's nameplate for running amperage and other electrical requirements.
-
Confirm its starting-current requirements.
-
Determine whether the application is a standard sump pump or a sewage ejector pump.
-
Compare these requirements with the latest Pump Sentry manufacturer specifications.
-
Select a compatible external battery and follow the installation instructions.
If you are unsure about compatibility, consult a qualified installer or electrician before purchasing.
Frequently asked questions
Is the Pump Sentry 1733 more powerful than the 822PS?
Yes. The 1733 has a higher continuous power rating and greater starting-current capacity.
Can I use the 822PS with a sewage ejector pump?
The 822PS is designed for compatible submersible sump pump applications. For sewage ejector applications, evaluate the 1733 and verify compatibility with the manufacturer.
Does either model include a battery?
No. Both require a separately purchased compatible external battery.
Will the 1733 provide longer battery backup runtime?
Not necessarily. Runtime depends on battery capacity, pump power consumption and operating conditions.
Can I install Pump Sentry with my existing sump pump?
Potentially, yes, if your existing pump meets the selected model's electrical and installation requirements.
