In this video Eric Aune shows how replacing valves in a laundry box can be a challenging task, especially when the box is buried behind the wall. The key to a successful repair is to properly source the right parts that match the existing box. By cutting a small hole in the sheetrock to gain access to the pipes, you can replace the valves without having to remove the entire box. Using VGA fittings to connect the new valves to the existing PEX tubing is a great way to ensure a watertight seal. It's important to clean up and leave the area better than you found it, using rags, paper towels, and cleaning solutions. By being prepared and thoughtful in your approach, you can efficiently replace valves in a laundry box without causing unnecessary damage.
