WHAT OUR CUSTOMERS SAY…

“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! ”

At Delany, we never rest on our past achievements like our first Flush Valve, the Flushboy, patented in 1927 or the other patented products like Rubber Sleeve Vacuum Breaker, introduced in 1945, or the Rubberflex Handle and Regulating Screw brought out in the 1950’s. As the industry entered the electronic age in late 80’s, it was Delany that first patented the top mounted, battery powered, sensor activated Flush Valve, the Impulse in 1988.

We can ship anywhere the US Postal Service ships. For orders being shipped outside the US, please contact us at (888) ASK-NOEL, noelsplumbingsupply@fuse.net, or via the text widget on this screen.

WHAT OUR CUSTOMERS SAY…

“Hey these guys are awesome! If you need a part for a fixture they have it send a picture and they can tell you what it is, they know their stuff, they have the weird obscure things you can't find unless you get a whole trim kit or whatever. Worth the trip and the money. They save you tons of time definitely visit ”
