What happens here

Obtain a new thermostatic mixing valve that matches the existing one in size and connection type (e.g., 1/2 inch sweat ends). The new valve typically comes factory-set to prevent scalding (around 115-120°F) and usually does not require immediate adjustment. However, it's a good practice to install the new rubber washers and screens provided with the new valve into the unions to prevent debris from entering the system.

Goal: Ensure the new valve is ready for installation with proper sealing components.

Okay, don't have to mess with that at all. There actually is a little thing. You can remove this cap and I'll show you in a minute to turn it up higher if you needed to. So once we shut the water down, all we're going to
