Mixing Valve Installation: Prepping the Area Mixing Valve Installation: Prepping the Area From "Ed the Plumber" episode DETP-105

A sweat valve can be installed to keep your toilet tank from sweating.

Host Ed Del Grande guides you in prepping the area to begin installing a mixing valve on your water line.

Installing a mixing valve will help to eliminate the sweating of a toilet tank. It allows the hot and cold water to mix. If the tank continues to sweat after this valve is installed, bump the hot water up a degree by adjusting the valve.
