Trying Something New

Review Posted 05/08/2024
I've been replacing the units I've been getting from the big boxes just about annually and am tired of it. The Little Giant was not a direct swap into place since the connection alignment is different but did wind up with a cleaner installation. I am happy with its performance to date.

Giant Of A Pump
By Bill S.

Review Posted 04/06/2022
We had to replace this pump after 30 hard years on the first one. Highly recommended. I had not expected pump to last as long as it did. New one fit perfectly and is working fine. If this one lives 30 years it will outlast me.

The Little Giant Is Just That
By Ronald K.

Purchased 12/02/2020 |
Review Posted 12/25/2020
Efficiently and relatively quietly pumps the basement clothes washer discharge 6.5 ft up to the main septic drain line without taking up a lot of space. Excellent little pump for this kind of duty.
