“I'm using this valve in a closed hydronic heating system with treated water (Central Boiler's "Inhibitor Plus" 1650XL). The first valve lasted from October 2010 to sometime during the 2013-14 heating season. The second valve lasted until this fall (November 2016) when I discovered the same problem - right at the mixing zone outlet area where the bronze casting meets the Teflon coating, the bronze appears to be eroded away so that hot water leaks past the seat, leaving the mix temp way too high. Unfortunately, my setup is tight, and changing to a different model/manufacturer would be problematic. Great when it's working...”

Only time will tell if the thermostatic element will last (most of the previous brands that I have installed lasted only about 3 years.) This model allows me to adjust it to meet the new code (”

They emailed me the shipping label (I paid for the return) when I was still on the phone with customer service, and placed the order for just the mixing valve. EXCELLENT SERVICE!”
“Same dimensions as other mixing valves, making it easy to change from other brands. Also works with higher input temp of 200 deg instead of most others at...”
