“I sent in photos of a broken cartridge (still installed, couldn’t take it out myself due to water shut-off restrictions in a condo) and even with the limited view they were able to tell me the exact part I needed so I could have it ready for the plumber (meaning I didn’t need to pay for a plumber to come out twice!!) ”

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.

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.

“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! ”
