They look similar to ordinary shower and tub valves and are equipped with a special diaphragm or piston mechanism that immediately balances the pressure of the hot- and cold-water inputs, limiting one or the other to keep the temperature within a range of several degrees.
Do shower valves have anti-scald?
An anti-scald pressure balancing valve is a special device that’s built into the shower handle that regulates the water pressure from the hot and cold water lines to prevent sudden, extreme changes in temperature. If your shower doesn’t have one, your water temperature may get so hot it can cause burns.
Can I remove the anti-scald valve?
Pry the cap off handle’s center exposing the screw underneath. Take out the center screw with a screwdriver or use an Allen wrench loosening a hollow-set screw in the side. Pull the round, metal plate on the valve assembly’s end toward you in the open, locked position.

Remove and Adjust the Scald Guard Grab the scald guard with your fingertips and pull it from the handle assembly. Rotate the guard counterclockwise to increase the water temperature and counterclockwise to decrease it.
How do you adjust anti scald devices?
Slide the shower handle off the stem to expose the “Rotational Limit Stop” anti-scald valve. Grab the center of the “Rotational Limit Stop” and pull it toward you. Turn the Delta anti-scald valve to the left to increase the maximum temperature of the water, or turn it to the right to decrease the water temperature.
How do I turn on anti scald device?
How do you replace an anti scald valve?
Are anti scald valves required?
These valves shall be installed at the point of use and in accordance with ASSE 1016 or ASME A112. Many reported incidents of serious burns and shocks received while showering have prompted the requirement for anti-scald shower valves, thermostatic mixing or pressure-balancing shower control valves (see Figure 408.3a).
Why is my bathtub leaking underneath?
Leaking drains are a likely cause of water that seeps from underneath your bathtub. This could be a leak coming from under the drain, which would require the help of a plumber to set right. However, a leaking tub drain could also be caused by a failing seal in the vicinity of the drain assembly.
How does scald guard work?
Pressure Sensitive Anti Scald Valve The device works by balancing the pressure between incoming flow of hot and cold water. If there is a shortage cold water supply, the equipment senses the difference and regulates hot water’s pressure. This prevents overheated water supply from shower heads.
How do you turn off scald guard?
How do you adjust a scald valve?
How do you remove a scald guard?
Do kitchen faucets have anti-scald?
One-handle hot and cold faucets can also come with something called a scald guard, controlled by an adjustable knob. This prevents water becoming dangerously hot. However, if this scald guard is set too high or is malfunctioning, your one-handle kitchen faucet can end up feeling far too hot.
Why does my faucet drip after I turn it off?
The faucet valve (working parts) is housed in the handle and controls the on/off, volume, and temperature control. Over time, a faucet valve can lose its ability to make a water-tight seal, so water will drip out even in the off position.
