Product Description

Amazon.com Product Description

The Wayne 3/4 HP stainless steel submersible sump pump is designed for use in basements that frequently flood. It fits in sump pits nine inches on level and four inches off level, with a ceramic mechanical seal for durability in basements with the highest water tables. The pump is made from rugged cast iron and rust-resistant stainless steel housing and fasteners. A 1-1/2-inch NPT discharge clears out your basement quickly. The mechanical float switch provides reliable operation and allows for installation in sump basins with an 11-inch or greater diameter. A top suction strainer filters out debris. The glass reinforced poly-carbonate impeller is intended for years of use, and Wayne backs its pump with a three-year limited warranty.

2.0 out of 5 stars WARNING: Contains parts expected to be replaced every two years, November 24, 2008

This review is from: Wayne CDU980 3/4 HP Stainless Submersible Sump Pump (Tools & Home Improvement)

After my builder's grade sump pump died after six years of use, I decided to upgrade to a better unit. Worked good for the first two years, but now will not engage by itself. I can tap the float to make it work, but it will not work on its own when the water level requires it to turn on.

After collecting model/serial number & purchase info, I contacted Wayne. As covered in other reviews, the lifetime warranty covers very little of the unit. In fact, the company's customer support folks expect for the switch to be replaced every two years at over $30 a pop. The switch includes the cover assembly, and you must drain and refill the oil before replacing the switch and top. Directions for performing the switch are not readily available - their response was "call us if you run into any issues".

This requirement doesn't make the price competitive when comparing to other 5-year plus models, including the time and mechanical/plumbing know-how to pull the unit, disassemble, replace, reassemble, and reattach the pump. Unless you're used to part swapouts and reinstalling a pump every two years, I would look elsewhere.

1.0 out of 5 stars Fake Lifetime Warranty!, October 2, 2008

I bought a Wayne CDU980 thinking that it would have a Lifetime Warranty. At least that is what it said on the Wayne Pumps website. It is not a real Lifetime Warranty. It only covers a repair/replacement ONCE! And only for the original owner! And it DOES NOT cover Wear and Tear! I feel like I have been scammed. I will never buy another Wayne product. I should have known better and checked before I bought it but I thought Wayne was a respectable and trusted company.

2.0 out of 5 stars Float switch questionable`, January 15, 2007

2 months after installation, pump malfunctioned and required that the float switch be manually cycled in order to function. If I had not also installed a battery backup pump I would have had a flooded level.
