Step1: Install the ball valve to the pipe.
To install the ball valve, shut off the main water supply line, turn on a faucet on the water supply line, drain out the remaining water and air in the pipe. Locate the ball valve's position to be installed, use a pipe cutter to cut the sides of the pipe. Put the ball valve into the spliced pipe. Please note that sweat joints/plumber's cement(not included) may be needed to secure the installation. Depending on the type of the pipes, couplers(not included) may also be required to close the installation.
