Turn the valve clockwise to shut off the water supply. For localized shutoff, check if there are separate valves near the bathtub or within the basement’s plumbing system.

Shutting off cold water in a basement bathtub involves locating and operating the main or local shutoff valves. This procedure is essential for plumbing repairs or emergencies. Ensuring you have easy access to these valves can prevent water damage and simplify maintenance tasks.
