Mixing valves have been a source of frustration for many home owners. This is a relatively new addition to the Ontario plumbing code. Chances are that if you own a home, you’re probably at an age where you grew up without a mixing valve on your hot water heater.
What is The Purpose of The Mixing Valve?
Your mixing valve is designed to lower the temperature out of the hot water tank to avoid burning. If the temperature inside the hot water heater is too low, bacteria will grow. The temperature at which bacteria won’t grow, is considered too hot for use, and could cause serious burning to the elderly or to children. To solve this problem, the hot water heater is kept at a higher temperature, and when you open a faucet, the mixing valve will add a little bit of cold water to cool down the hot water we receive at the fixture. This way if a child or elderly person finds themselves in a situation where they’re in the bathtub with only the hot water on, they won’t end up with third degree burns.
The Problem With Mixing Valves
Since the new code requirement, there have been many problems with mixing valves. They haven’t been able to design one that seems to last more than a few years, with many of them failing inside of two years. Many homeowners are asking plumbers to remove them due to the fact that it will add an extra $450 expense every two years. Nobody really needs that kind of headache. Hopefully the manufacturers of these devices will step up to the plate, and offer a product that’s worthy, and will last as long as your water heater would. In the meantime, plumbers in Ottawa will just have to deal with this.
