WHAT OUR CUSTOMERS SAY…

“I have been here a few times. And I have found it the most helpful and best place I've been to in this area. They explain to me what I need not what I'm trying to tell them what I want. Would recommend to anybody who needed help and plumbing parts. ”

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.

WHAT OUR CUSTOMERS SAY…

“Y'all are amazing. I live in Texas and it's faster to order express from Noel's than go to local parts stores. Customers can text Noel's a picture of the part they need and Noel's will find that part or the equivalent and text the link. They have 2-3 day shipping available. The staff answers the phone quickly, politely and they know their stuff! The unit I needed plumbing parts for was built in the 30s. No matter, Noels has me covered. I highly recommend them. Thank you Noel's for your efficient, old school excellence combined with current technology! You have saved me so much time, money, and aggravation! A++++++ ”
