Rated 4.0 out of 5 by 3 reviewers.
Rated 4.0 out of 5.0 by install was pretty easy installation was pretty easy. directions had good detail. the pump seems to have a good flow rate, that it should prevent any possible overflow in the event of power loss. September 6, 2013
Rated 3.0 out of 5.0 by So so This is the third one of these I have installed in the same sump in about 12 years. It is almost never used but it fails anyway due to passage of time. I think the gallon per hour spec supplied by Wayne is "very optimistic". June 25, 2013
Rated 5.0 out of 5.0 by Best price I found for this product I had this same product, but 20 years old and needed to be replaced. Went with same item for ease of installation. January 30, 2015
