1/3 Verifying the Water Supply is Off

Ensuring that the water to your toilet is truly shut off is crucial before embarking on any repairs or maintenance. Fortunately, there are a few simple steps you can take to confirm that the water supply has been successfully turned off. Here are three effective methods to check if the water supply is off: First, locate your water meter and observe the dial or digital display.
