Hi, this is my first post, glad I found this place. I have an old Ridgid 1/2hp sump pump that has been going strong for at least 5 years. I was thinking of replacing it with the same model but it looks like the quality has gone down with a lot of bad reviews so I decided to purchase a m57 Zoeller sump off of Amazon since it has stellar reviews. I'm thinking of downgrading to a 1/3 hp because my pit isn't that big and the 1/2 cycles on and off sometimes every minute during big rainstorms. I'm thinking maybe a 1/3 would cycle slowing and extend the life of the pump. Only thing I'm worried about is if it won't be able to handle the load, my pit is very shallow and is only 15" wide by 18" deep. The 1/3hp Zoeller handles around 34 gpm while the Ridgid handles 53 gpm at 10ft of lift.
