Best Combination Sump Pump Systems
Combination sump pumps are great if you want to have complete flooding protection for your basement. With two pumps ready to take on the job in any circumstances, you’re sure to have peace of mind you haven’t for years.
These pumps are perfect for many homeowners thanks to their compact assembly. You won’t have to fit the second pump yourself and all you have to do is drop it in and connect it to your system.
In this article, I’ll share with you which I think are the best combination sump pump systems available today.

The Best Combination Sump Pump Systems
The Wayne BGSP50 is the ultimate battery backup sump pump package you can get for your home. A well-rounded system with top of the line specifications.
It packs a primary and backup that can reach up to 3840 and 2040 GPH respectively, up to 10 feet. That’s a more reliable backup on its own than the WSS30Vn.
My favorite part about it is the switch. There’s a solid-state switch that uses air pressure to sense the water level. Backed by an electromechanical reed float in case of failure.
It has a system that monitors parameters and conducts system tests on its own. You can connect it to the WiFi to receive alerts. When the WiFi’s down, the LocalLink technology allows you to check on it even from your own bed. No more having to go down the basement.
The only caveat, as you probably expected, is that it’s not cheap. But you can’t put a price on peace of mind and that’s exactly what this gives.
For a bit of an improvement in quality over the Basement Watchdog, Glentronics also offers the PHCC Pro-Series pumps. The PS-C22 is their take on an industrial grade combination sump pump system for residential applications.
It packs a primary pump that moves up to 2770 GPH and the backup up to 1850 GPH to 10′ of elevation. That’s a more balanced pair of pumps than all of the other pumps here except for the Zoeller.
Like its cousin, the DFK961, the PS-C22 is equipped with a dual float switch for each pump. It also has a great monitoring system with helpful alarms and USB capability to PHCC Pro Series CONNECT modules which is nice. The module allows the system to send you texts and status alerts with no monthly fee.
Liberty Pumps is one of the most popular brands in the sump pump industry. The PC series combination pumps are for those who want a reliable combo system that works.
The assembly packs a primary and backup capable of pumping up to 2580 and 1500 GPH at 10′ of lift respectively. It’s highly compact making it perfect for small diameter basins as small as 15″ in diameter.
Like the more expensive options here, it also features a self testing and alarm system to tell you when something’s wrong.
This is a great choice for people who want great features and a brand you know you can rely on.
Basement Watchdog is one of the well-known brands in sump pump technology. They produce high quality products at affordable prices. Favored by both pros and homeowners, it’s a brand we just can’t afford to leave out of this list.
The DFK961 is their entry into combination pumps at the 1/3 HP range. It packs a primary and backup that can move up to 3100 and 1000 GPH respectively, both at 10 feet. Like the WSS30Vn, there’s an imbalance that makes it rely too much on the main pump. This is bad if you have large amounts of water coming in.
What I like about it though is the dual float switches for both of the pumps. It gives the system 4x the protection by having a failsafe for the most sensitive part — the switch.
What is a combination sump pump?
A combination sump pump is where an typical AC powered and a backup battery powered pump are asssembled together. The arrangement helps provide continuous protection even when the primary pump fails due to damage or power outages.
Commonly referred as combo sump pumps, this system is preferred where convenience is a primary concern. With a combination system, all you have to do is drop it into the pit and connect a check valve to the discharge. You won’t have to create the mounting and find the space for another pump such as when adding to an existing sump pump.
The capacity is the most important factor when choosing the pump. You should measure how much water goes into your pit in a minute and find a pump above that clears that in half the time.
You also want both the primary and backup pump to have about the same capacity as each other. Since the backup has to work alone in case of the primary’s failure, it has to be able to do the job on its own.
A great sump pump combination should have both pumps made of corrosion resistant materials. It should be able to withstand several years of the harsh environment inside the pit.
Cast iron is great and is the go-to for most people. It has great cooling properties and durability. After a few years, however, it will start to corrode when the coating goes off.
Plastic pumps counter this but they sacrifice a bit of the cooling property. This may make the pump overheat specially when it has to cycle every few minutes.
Although price shouldn’t be the main factor in choosing, we still have to consider it as a matter of practicality. Systems like the BGSP50 are jam packed with features but they may be too expensive for the average user. If so, you should try to get a pump with nearly the same capacity but with less extras.
Combination pumps are a great way to provide all around protection for your home. They’re cheap (cheaper than water damage repairs, anyway) and really easy to install. Taking away all our stress and worries of a flooded home.
Lucky for us, there are an increasing number of manufacturers in this market. This means better and cheaper options for all of us. All we have to do is choose one that best fits our home.
