Pump works very well. Highly suggest it.

### ⭐⭐⭐⭐⭐ Best Sump Pump I ever had
*by R***3 on February 25, 2022*

We have two sump pumps in our basement to keep it nice and dry. Every 4 years or so, even less, we have to replace one. I have been buying the same brand every time and thought there has to be something better. I have read how good the Wayne sump pumps are and decided to try one out. I got the model WAYNE CDU790 and it is absolutely great. Right away out of the box you can feel is it quality. The old ones I bought were thermoplastic and only one lasted the expected 5 years. Some lasted a little over 4 years, most did not. The cast iron is heavy duty with stainless steel hardware holding it all together. The impeller is also stainless steel protected by a cast iron shroud. It has a long cable for reaching the outlet. The installation was very easy, and the operation is so quiet that I was worried that it wasn't working. I had to remove the cover to see if it was working and it is. My old pumps were so loud you could hear them upstairs every time they ran. The Wayne pumps water MUCH faster than the old pumps I bought. The sump empties in a matter of only a few seconds. This is a solid sump pump with a 3 year warranty. I registered it online immediately and am confident it will outlast my old pumps by far. The expected life if 6 years. For all of that, I give it 5 stars. Also for a super value and price as well as terrific quality.
