“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. ”

“This place is amazing. I live in San Antonio, Texas and there are a few plumbing stores with vintage parts but they never have what I need and the ordering process takes them weeks. I found a rare part at Noels by reverse image search but they will do it for you. I've used them 3 times. Their agents are knowledgable and polite. They will find you the same part or the after market part and get you going on your way. They have 2-3 day shipping. My house was built in the 30's and they know exactly what the after market parts are that I need. I save money and time going to them. I sure wish they were in San Antonio! I will just go directly to Noel's next time - they are LEGENDS! ”
