Poor quality control.
Worst product integrity I've ever encountered. The product came in a box, that had said it had been factory tested for quality. The unit rattled and I found that all of the screws that hold the bottom section on were either very loose or missing. If I installed it, I would end up with a flooded basement. No way this product was tested or even given a visual inspection. I did not order another Zoeller and they owe me a couple hundred, for the aggravation and disappointment.
g0lf32, we acknowledge the inconvenience this must have caused. We strive to create durable, quality products, and I would like to assure you that the particular product you purchased was an unfortunate anomaly. Please feel free to reach out to our Product Support Team, 1-800-928-7867 with any questions, concerns you may have or for warranty information. We are available Mon. to Fri. 8am to 5pm eastern. We value your business and hope to provide better products and services to you in the future.
