“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. ”

“Fantastic! I walked in with parts to the faucet in my vintage sink and walked out with everything I needed. Chain hardware stores suggested I get a whole new sink and/or would not be able to do it without a plumber. The employee at Noels took a quick look, knew what it was, and had it in stock. I was able to fix my sink in two minutes with their help! ”
