"I only buy your products. I LOVE and trust your products, but I LOVE your technical service group MORE!!! They are always kind, courteous, and helpful. They have stayed on the phone with me and walked me through repairs. As a single mother, this service is invaluable. I won’t buy anything else and I recommend your products to all my friends. Keep up the great work!"
From M.S. in Florida
"I had planned on sending an e-mail to the president of the company. I am 92 years old and have used your product for many years. Not being a plumber, I have appreciated your product because of its ease in installing. And so I thank you for your help. I have a three bath home, and all toilets now have your fill valves and flush valves."
