Disassemble the faucets of the shower to replace the shower valve and cover the shower drain or the tub using a cloth or a drain stopper; you need to ensure that you block the opening of the drain completely to avoid any small components or screws from getting into the drain. Next, unscrew the shower handle to remove it; you might find a cap covering the screws holding the handle together.
After unscrewing the screws from the handle, you might need to wiggle or tap it to make it loosen and then remove it. Next, place the screws and the handle safely and keep them together; therefore, after finishing the replacement process, you can reassemble them and put them in place. Then, you will need to remove the escutcheon or the trim plate.
The escutcheon is the plate made of metal used to cover the hole in the shower wall or the tile; the shower valve will be behind this wall. First, remove the plate from the wall by unscrewing its screws; if the plate is fixed with caulk, you can use a utility knife and remove the metal plate. After removing the escutcheon, “the metal plate,” and its screws, you will need to put them together in a safe place.
You can clean the trim plate and the handle; since you have removed them, you can clean the debris, like soap scum and limescale, from them. To do this, you can soak them in a lime remover or white vinegar while you are replacing the shower valve. Next, you need to cut off the shower’s water supply and locate the shower’s shutoff valves to stop leaking after replacing the valve.
On the sides of the valve, you will find the shower’s shutoffs, one is for the hot water, and the other is for the cold water; the two shutoffs need to be shut down. However, if you can not locate the shutoffs of the shower valve, you can turn off the main valve which is used to supply the water for the house during the replacement process.
The hole you will find behind the metal plate may not be big enough for you to change the valve through it; therefore, you will need to make a bigger hole in the tile to be able to change the valve. The hole for changing the valve is typically around twelve inches by twelve inches; this size is suitable for changing the valve and will be easy to repair after finishing the replacement process.
When enlarging the hole behind the metal plate, make sure not to make it very big because it will be harder to repair it later; you will need pliers to remove the clip valve; use the pliers to remove the clip from the top of the valve. The clip is used to fix the valve in place; after removing it, you need to keep it in a safe place.
Some showers use retainers instead of clips to fix the valve in place; you can use a wrench to remove it from the valve; after removing the retainer, you need to keep it safe.
The last step is to remove the valve from the wall; you can use the pliers to remove it by wiggling it to make it looser and easier and hold the valve from its carriage by the pilers to remove it. Next, place the new valve, reassemble each part you have previously disassembled and then turn on the water supply.
