Line on the side and a cold one over here in the to come into this mixing valve and make that water temperature just perfect that morning shower. Yes what are you doing next. Next we'll clean all these fittings. They have to clean -- all the different pieces of copper before you can sweat joints right. And that is basically so that so that the welding or heard soldering process -- works appropriately. We -- that -- it is it like a copper screen yes it's it's it's Emery cloth it is a fine Emery cloth yeah. Good was sent him. We're all valves are you. Temperature balance valve. You know the the use of copper piping I guess. Is a little controversial in some parts of the country what we still used around here.

Is there are drying time with the flux you have to worry about being quick no not at all you know it just stays on there. Now look circus in place. Does it have to be level. Yes what. We'll center -- right on the whole existing home. -- and didn't look a little bit still.
