“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! ”

This Pressure Balance Unit maintains a constant output temperature in response to changes in hot and cold water supply pressure. This means there’s less chance you’ll experience dramatic changes in water temperature. The diaphragm system with integrated check valves is engineered to eliminate cross flow and this Pressure Balance Unit is also designed to avoid failure due to mineral deposits, so it is ideal for use in hard water areas.
