When you turn on your hot water, you don’t expect to get burnt, but it does happen at times. The water coming from your water heater can be as hot as 160 degrees, and that could easily scald exposed skin. For some homeowners, a faulty or even missing anti-scald valve is the culprit.
An anti-scald valve mixes the hot and cold water that is coming through the pipes to control the temperature. It also serves the purpose of offsetting sudden drops in pressure on either line, such as when you flush a toilet or run your dishwasher. Without an anti-scald valve, you will feel the effect of those things immediately when you’re in the shower.
Replacing or installing an anti-scald valve is not a very complicated process, so it can be taken care of fairly quickly without disrupting your daily routine too much. It is important to remember to turn off the water supply before doing any work on your plumbing to prevent a small job from turning into a disaster.
