This can be a problem if you have a large amount of water flowing through.

What is a combined sump pump?

A sump pump that is a combination in which a standard AC powered and backup battery-powered pump are combined. The system provides constant security even if the primary pump is damaged or fails due to power failures.

Often referred to as combination sump pumps, this method is favored when convenience is a major concern. When you have a combination method, the only thing you need to do is put it inside the pit, and connect an appropriate check valve to the outlet. It is not necessary to design the mounting, and you can find room for another pump, for instance, when you are adding it the sump pump to your existing.

Buyer's Guide

1. Capacity

Amount is by far the main aspect to consider when selecting a pump. You must determine the amount of water that flows into your pit within a minute, then choose a model which can be cleared in less than half of the amount of time.

Additionally, you want the primary pump and backup pump to have the same capacity. Because the backup pump has to function on its own in the event an issue with the primary pump the backup pump must be capable of doing the work by itself.

2. Build

A good sump pump combo must have both pumps constructed from corrosion-resistant materials. It must be able to stand up to the harsh conditions inside the pit.

Cast iron is a great material and is the choice of the majority of people. It is extremely cool and is durable. After a couple of years, however, it'll start to corrode as the coating wears off.

Pumps made of plastic counter this, however they lose a little of cooling. This can cause the pump to overheat, especially when it is required to cycle on a regular basis for a couple of minutes.

3. Price

While price should not be the primary element in our decision-making however, we must take into account it in terms of practicality. The BGSP50 and other models such as the BGSP50 come with a lot of options, but they might be too costly for the average person. If that is the case, consider an alternative pump that has the same size, but with fewer features.


Combination pumps are a fantastic option to offer all-round security to your house. They're affordable (cheaper than water damage repair in the end) and easy to put in. They take away our anxieties and fears of a house that is flooded.

For us, it's a blessing that there is an increase in the number of companies in this market. This means more affordable and better alternatives for everyone. All we need to do is select the one that is best suited to the space we live in.
