The product, in the report: Taco 5000 Series Lead-Free Mixing Valve, designed to regulate, to a preset temperature, hot water coming out of a domestic hot water heater by automatically adding cold water. From the manufacturer’s specification sheet: “This versatile NSF 61 and ASSE 1017 mixing valve provides the ultimate performance for domestic hot water applications. The 5000 Series ASSE 1017 certification allows for domestic hot water storage at temperatures high enough to increase the effective storage capacity of a water heater, kill harmful bacteria and still be delivered at a safe 120 °F or less. The valves unique design and advanced thermostatic element ensures a stable mixed water temperature throughout the extended 85 °-176 °F range.”
We installed a Taco 5000 mixing valve to regulate water coming out of our domestic hot water heater to a safe temperature. Even though the thermostat on the water heater is set to 120F, the thermostat’s temperature sensor is located in the center of the tank, so, due to water heater stratification, when the tank sits unused for a few hours, the water at the top of the tank, where the water exits, can reach temperatures of 150F or more.
Water heater stratification is a common problem with water heaters. The usual solution is to install a valve, known as a mixing valve, to automatically mix the hot water with cold water to reduce the water temperature to a safe temperature of 120F or less.
There are many manufacturers of water mixing valves. I purchased one made by Taco, a large manufacturer of plumbing products with a good reputation. However, we had problems with this valve from the beginning, when we first installed the water heater and Taco 5000 mixing valve in 2006. The temperature of the mixed water coming out of the valve seemed to vary considerably, sometimes reaching levels of heat that were unsafe.
Thinking that our original valve was somehow not working properly I replaced it with a new version of the same valve two years ago, in 2019. But the problems persisted even with the new valve. I did note similar complaints from other users on various web sites.
I finally decided to investigate the problem by gathering data. I installed digital temperature sensors on the hot inlet and mixed outlet ports of the Taco 5000. I found that the valve does not perform in a safe manner, because, once activated by water flow, it takes more than two minutes for the valve to reduce the output temperature to 120F, and even when it reaches 120F it is quite unstable, varying plus or minus 5F.
I replaced the Taco 5000 mixing valve with a [REDACTED] mixing valve. The [REDACTED] valve works absolutely perfectly.
I’ve posted videos on [REDACTED] of the Taco 5000 and [REDACTED] mixing valves in operation. The videos demonstrate exactly what I am talking about.
