WARNING

Hot Water Can Scald!

Water heated to temperatures for clothes washing, dish washing, and other sanitizing needs can 

scald and cause permanent injury.

Children, elderly, and infirm or physically handicapped persons are more likely to be 

permanently injured by hot water.  Never leave them unattended in a bathtub or shower.  

Never allow small children to use a hot water tap or draw their own bath.

If anyone using hot water in the building fits the above description, or if state laws or local 

codes require certain water temperatures at hot water taps, you must take special 

precautions:

Use lowest possible temperature setting.

Install some type of tempering device, such as an automatic mixing 

valve, at hot water tap or water heater.  Automatic mixing valve must be selected and 

installed according to valve manufacturer’s recommendations and instructions.

Water passing out of drain valves may be extremely hot.  To avoid injury:

Make sure all connections are tight.

Direct water flow away from any person.

Protection Must Be Taken Against Excessive Temperature and Pressure!

--Installation of a Temperature & Pressure (T&P) relief valve is required.
