One of the safety concerns you might not consider in your home is the temperature of your tap water. If your water heater puts out 160 degree water, scalding could happen after as little as a few seconds. To prevent extreme water temperatures from your faucets, you should have an anti-scald valve installed.
Anti-scald valves mix the incoming water to obtain a manageable, even temperature. You could install one of these yourself if you have some experience, but there is always the option of having a plumber do it for you. If you decide to install it yourself, make sure that you turn off the water before starting work.
Anti-scald valves will not only present burns and give you more comfortable control of your water temperature, but they can also prevent the sudden change in water temperature when someone flushes a toilet or completely opens another faucet.
