Nick Marine: Hello! This is Nick Marine with Marine Plumbing Service. Today, we are going to teach you how to replace an old tub-and-shower valve. What we are going to be covering today is the removal of the actual old trim, the shower head, the face plate, the handle of a tub spout and cutting an excess from behind the wall and roughing in or soldering in a new American Standard tub-and-shower valve. Then finally, once the valve is roughed in, we are going to be putting on a new trim which is the face plate, the handle, the tub spout and the shower head.

Some of the tools you are going to need today to get started would be a 4 In 1 screwdriver, a pair of channel locks, a metric and American Allen key set, key hole saw, caulk gun, lead-free solder, flux, paste, MAPP gas or propane gas, a torch tip, hacksaw, a drill, a sawzall and that should get you started.

Some of the important things; you really have to have a neck for soldering. When the temperature of the MAPP gas get excess of 1200, you could start firing your valve, you could catch insulation on fire. So it's best to call a master plumber if you have any hesitation at all when you are using a solder torch. Also, the molten solder can drop down into the surfaces below and also catch things on fire. You are also messing with water so when you are cutting into the water line, always have someone else in the house to turn on the water while you are upstairs to pressurize the system because it only takes a few seconds to completely flood or devastate the home. Always, if you have any doubt, call a state-licensed master plumber.

I am a third-generation master plumber; Georgia's first licensed Green Plumber in the State of Georgia. Whenever you are installing a faucet in a wall, make sure it's a company you can trust because you are not going to able to see this or maintain this. Once it's soldered in, that's it. American Standard is a name you can trust; they have been around for 140 years and it's what I use. Okay then, so let's gets started.
