“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! ”

“I was very happy with Noel’s Plumbing. I was searching for a fairly rare part and saw it listed on their website. After placing my order, I was informed that the item was actually on backorder. Noel’s Plumbing was upfront and honest right away, letting me know it might take some time to arrive. Throughout the wait, they consistently kept me updated, which I really appreciated. When the part finally came in, they shipped it out immediately. It arrived exactly as described and was precisely what I needed. Excellent communication, honesty, and follow-through. Thank you, Noel’s Plumbing! ”
