The job: A Rancho Cucamonga warehouse needed three 2½-inch valves on its main water supply replaced. The valves sit 35 feet up, along the ceiling.
How we did it: Our crew worked from a scissor lift, fully harnessed and tied off. We installed new full-port brass ball valves on the copper line with press fittings, so there was no open flame near the insulation overhead.
The result: The building's water was turned back on, and every valve was tested and tagged before we came down.
Tip for homeowners: Find your home's main water shut-off before you need it. Turn it off and back on once a year so it doesn't seize. If it's stiff, drips at the handle, or won't shut the water off all the way, have it replaced as a planned job instead of an emergency.
