Dont Buy Unreliable
By A. Miles
I like the pump design I have had both ACE and Wayne 1/3 and 1/2 HP pumps. There are two problems - switch life is 2 years or less depending how often its used. The float rod is regular steel and rusts causing the float to stick, which causes the pump to stay on or off. I can't figure why Wayne would make a great pump with lousy parts. Yup I can typical American manufacturer; no life testing and poor quality control. Recommend you stay away from Wayne pumps. Remember you don't need the pump when its dry - they fail when you need them the most, in a rain storm at 2 pm or when your on vacation, again stay away from these Wayne pumps. They have known about these design flaws for years and done nothing about it.

Long lasting and reliable
By Bob
My first pump lasted 22 years so when it developed a ground fault I replaced it with the same model. A 22 year life with no problems - no complaints!

By Lawrence Coppari
Pump arrived promptly and works as advertised. I am a satisfied customer. I have no hesitation recommending this pump.I had a flooding problem in my driveway across from several garages. The water had nowhere to go but eventually would reach the point where it would flow down sidewalk across front yard removing mulch from flower/shrubbery beds. The pump was placed in a sump that holds about 15 gallons. It is fed by two drains located at driveway low points and piped to sump. With moderate rainfall, pump comes on about every 40 seconds for a 9 second interval. For very heavy rainfall, pump comes on about every 11 seconds for an 11 second run. I have pump exhausting through a 1.5 in PVC pipe about 60 feet long to city street. The pipe goes uphill about 3 feet including its depth in sump. Calculations indicate it is putting out about 1900 gpm to street. Pump is rated at 2800 gpm for a 5 ft. head. Head includes altitude change as well as pipe losses. Therefore with 60 feet of pipe plus some elbows, the rate must be less.
