Delta shower valve won’t get hot
Posted on May.18, 2013 by Chase Thompson

One of the common issues that we run into from time to time is a homeowner who has installed a Delta shower valve or cartridge in their home but for some reason the water just doesn’t get very hot. 

This is actually a very simple and easy repair that doesn’t even require the water to be turned off. The delta shower cartridges are equipped with a safety feature that is designed to prevent scalding from water that is too hot. It’s almost like a built in thermostat for your hot water. If you remove the handle and trim sleeve to reveal the cartridge you will notice that there is a setting on the side that has a H & C and several indicators in between. To adjust this setting you may need a hex screwdriver to remove the set screw. Once this is out of the way you should be able to pull out the plastic thermostat adjustment and turn it to the hot setting. From the factory, they will always be set to cold.
