“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! ”
