This is a great company that offers a quality product, along with the very best customer service I've ever encountered. I can't do it justice here, but I was able to repair my under-the-counter filtration system with the part-by-part, step-by-step, personal assistance of a wonderful customer support person over the course of a full month, with back and forth emails. Now try finding that elsewhere these days. I've been a customer for the past 20 years...I'm now a customer for life.
