How To Install A Shower Faucet

The first step is to ensure that you attach the valves to the framing to be able to route the pipes correctly; this done before installation of the pipes. Install a two by six block into the framing of the enclosure. This will support the valve, the shower head, and the spout. While installing the block ensure that it faces towards the shower.

The height of the valve should be convenient for both adults and children when operating the handle. The recommended height is about 40 inches. The valve installation instructions specify the distance from the block to the front of the wall. So you should account for the thickness of the wall covering including the backer board.

Secure the faucet valve to the blocking with screws, and ensure it is positioned in the correct orientation.

Now, connect the pipes supplying water to the water inlets. While doing this, you will need to follow the procedure as per the model of the valve. Some valves have a male threaded port while others have female ones, and still, others have slip connectors. When you connect the pipes with threaded fittings, wrap a plumbing tape around the head first. If you solder the pipes into slip connection use lead-free solder and a propane torch.

In the connection, you will screw the threaded adapter and reinforce with a plumbing tape. Fit the pipes tightly and solder all the joints.  It is essential to install a water hammer arrestor into each of the hot and cold water supply near the valve. Such fitting prevents banging in the pipes whenever you turn on the faucet.

Every valve has a threaded outlet on top for the pipe that goes to the shower head. When the faucet controls a tub spout also, it will have an additional outlet. Install a 1/2-inch pipe from the valve to the blocking for the shower head. Terminate this pipe with a brass elbow that is threaded. This fitting has ears for screwing to the blocking. Secure the brass to the blocking using screws. This is how to install a shower faucet new construction.

Similarly, install a pipe for the tub spout. To keep the debris out of the pipes, into each elbow you will screw a temporary nipple about six inches, as you finish the wall. Cover the walls, leaving a gap about half an inch around the valve handle and the nipples. Cover this space with the trim that comes with the faucets. This is how to install a tub shower faucet single handle. The trim has faceplates for the valve and for shower arm, an escutcheon. Note that the tub spout doesn’t need the trim.

Loosen the nipples and using plumbing tape wrap the shower arm and spout nipple, then tighten them. Seal the trim and the tub spout using silicone caulk, a necessary step to keep moisture out of the wall.
