“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! ”

“The vacuum breaker on my outdoor spigot failed and Noel's Plumbing was the only placeI could find that had the appropriate mfr. part. I sent a text with photos on Wednesday evening to make sure the part I found was correct. In less than 2 hours later, I had a reply confirming it was the correct part. Placed my order that evening and received the part on Saturday afternoon (about 2.75 days) and my plumbing issue was resolved! I highly recommend - I really appreciated the prompt and pleasant response. ”
