To install a 3-way shower diverter valve, follow these steps: 1) turn off the water supply; 2) remove the old valve and prepare the area for the new valve installation. When renovating a bathroom, installing a new shower is a common project.
One essential component of any shower system is the 3-way diverter valve. The valve is responsible for controlling the flow of water, directing it to the showerhead or faucet, or both. Usually, showers have a single control valve that enables the water to flow either through the showerhead or through the faucet.
However, a 3-way diverter valve allows you to redirect the water flow between the showerhead and the faucet, so you can use them both simultaneously or separately. Installing a 3-way diverter valve requires a few essential steps, which we are going to mention below.
