“Outstanding fast delivery on two pieces of an ancient Wolverine bath stem for Kohler - from the early 40s I think. The new one has a different body design, but it screwed directly into the old hot/cold tree and was the exact 6" length. Forty eight hours after installation now, and all remains fine. Also, kudos to the people who set up the website and ordering process. Great work - clear photos and info ! PS: I'm not an employee or family...lol. I retired from electrical wholesaling here outside Chicago and I appreciate a good job. ”

“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! ”
