“Recently I purchased a rebuild kit for my American Standard R series bathtub faucet. I want to say thank you for carrying this product. The rebuild kit worked beautifully and I was able to save the original look and feel of our 1957 bathroom. Thank you! ”

“After trying all over my area, I couldn't find the part for the faucet in my older house. The part I needed was found on the first try on their website and ordering was very easy. It was after hours, but someone responded to my text right away. The part was shipped the next business day. After putting the new part in the faucet works better than it has for years! ”
