Shower Anti Scald Devices
Enjoy Your Shower With A Constant and Comfortable Temperature
Taking a shower can not only get you clean, it can be a very relaxing and
enjoyable experience, that is, if the water temperature remains balanced. Maintaining a
constant temperature is accomplished with an anti scald device.
Have you ever had the experience of being in the shower and having the water suddenly turn cold, or
worse yet scalding hot? This is something most of us have experienced at one time or another, but it need not
The reason this occurs is because someone in the household has either flushed a
toilet, or turned on a water supply elsewhere in the house. As a toilet is flushed and the tank is refilling it can
rob the shower of it's cold water supply suddenly creating a scalding torrent of water on the person in the shower.
Or if a faucet is being used to wash dishes or for some other task that requires hot water, the hot water supply to
the shower is diminished and you could be subjected to a very chilly downpour from your showerhead and a not so
This can not only be unpleasant, it could be potentially dangerous depending on
the intensity of the change in water temperature. In a household with young children this is a situation that
really should be avoided. Maintaining a reasonable water temperature is more important in a household with children
or seniors. Children and seniors have thinner skin and are more subject to burns if the water temperature
gets out of hand.
There are two ways to handle this problem. Most new construction requires that an
anti scald device be added to showers to handle this, but if you have an existing bathroom, this feature can be
The lesser expensive solution is a pressure balance valve. This will work, but
the overall delivery of water to the shower may be diminished to compensate and keep the temperature constant
within about three degrees.
The better, but more expensive solution, is a thermostatic valve which will keep
the water temperature constant in the shower and give you maximum flow.
Shower safely and avoid injury
Varying water temperature is for the most part, annoying and mildly
uncomfortable, however, there are also serious incidents that occur. Annually there are 3800 incidents of serious
injury and 34 deaths that occur from scalding tap water in the home.
Senior citizens and children 5 and under are the most at risk due to thinner skin
making them more vulnerable to burns.
The very minimum that should be done is setting the hot water tank to no more
than 120 degrees.
The better solution is adding an anti scald device to your bathtub or shower.
They can be added to control the water in just the shower or just the tub, or you can get what is called a diverter
that will control water temperature for both.
Add to both the comfort level of using the shower and tub, and at the same time
increase the safety factor for yourself and your household with the addition of an anti scald device.
Cautionary Tip: Installing a shower diverter valve is not
like putting together a BBQ where you throw the instructions aside and just plunge in. Study parts diagram and read
instructions carefully. If you install an anti scald device improperly you could damage the device and your
If you are not confident you can install the diverter valve yourself, then it is
prudent to use some of your remodeling budget to have it installed by a professional.
