Tip & How-To about Plumbing
Many people are turning their hot water heaters down to dangerously low temperatures to try to save fuel or energy. What they do not know is that they are playing a very dangerous game with a deadly disease.
Your water heater can be a very deadly incubator for the deadly Legonella Bacteria. In an effort to save money a lot of people have made the decision to turn the water temperature on their water heater down to very low temperatures. Temperatures of under 140F can allow the bacteria to grow in your hot water heater.
The way to combat this problem is to make sure that the temperature for your hot water heater is over 140F. The problem that is caused by those temperatures is that 140F water can be dangerous because of the risk of scalding. This risk is especially high for young children and older adults.
The question then becomes, what do you do to make sure that either of these problems are not a risk in your home. The answer to this question is to install a device called a mixing valve.
The mixing valve mixes some cold water with the hot water coming from the hot water heater. This mixing valve takes the temperature of the hot water down to a temperature that will not hurt people with tender skin. A water temperature of under 120F will give people time to react to hot water before it hurts them. The cooler water in the piping going to your faucet will not have the time to grow bad bacteria before you use it.
To review the thing you need to remember about this problem. Keep your water in your heater higher than 140F to keep the bad stuff from forming. You want the water coming out of your faucet needs to be under 120F to keep from scalding people in your home. And, a mixing valve will do the job of cooling off your water to a safe temperature.
If you are thinking of turning your water temperatures down be careful. Check into installing a mixing valve instead and keep your family safe.
