Assess Old Valve and Prepare Water Shutoff

What happens here

The video highlights issues with the existing angle valve, noting its awkward placement making it difficult to turn off and its stiff mechanism. To begin the replacement process, first locate and completely shut off the main water supply to the house or the specific area. Once the main supply is off, flush the toilet to drain the tank. To ensure the lines are fully depressurized and drained, also open other nearby water fixtures like a sink faucet to allow any remaining water or air to escape from the pipes.

Goal: Assess the current angle valve for functionality and accessibility, then shut off the main water supply to the area and begin draining residual water from the appliance.
