Restore Water and Test Operation

What happens here

With all connections secure, slowly turn on the main water supply to your house. Then, gently open the new quarter-turn ball valve at the toilet, allowing water to slowly flow into the tank. Observe closely for any signs of leaks at all connection points. Once the tank is refilled, flush the toilet to verify proper flushing action and that the tank refills correctly without leaks. The new quarter-turn valve should now be easy to operate for future maintenance or emergencies.

Goal: Slowly restore the main water supply and then activate the new angle valve, checking for proper operation and any leaks.
