The legendary Temptrol pressure-balancing, anti-scald mixing valve is the heart of every Symmons tub and shower system, and it is the benchmark by which all others are judged. Each valve is constructed of solid brass, bronze, and stainless steel, and features an adjustable piston that instantly and continually balances the hot and cold water pressure as demand fluctuates in the plumbing system. Now Temptrol is even easier to install with the Rapid Install bracket system for virtually any rough-in situation, and factory-installed options for various water supply connection methods.

WHAT OUR CUSTOMERS SAY…

“I was very happy with Noel’s Plumbing. I was searching for a fairly rare part and saw it listed on their website. After placing my order, I was informed that the item was actually on backorder. Noel’s Plumbing was upfront and honest right away, letting me know it might take some time to arrive. Throughout the wait, they consistently kept me updated, which I really appreciated. When the part finally came in, they shipped it out immediately. It arrived exactly as described and was precisely what I needed. Excellent communication, honesty, and follow-through. Thank you, Noel’s Plumbing! ”
