Reassemble and Re-test Valve Seal

What happens here

Carefully re-thread the retaining nut, now with Teflon tape applied, back onto the brass valve body. Use the adjustable wrench to tighten the nut firmly, but avoid overtightening which could damage the threads or component. Reconnect the flexible water supply line to the valve assembly. Turn the toilet's water supply valve back on and once again actuate the bidet control handle multiple times to rigorously test for any leaks. Confirm that no water is dripping from the repaired connection. If the leak persists, re-examine the Teflon tape application or consider replacing the retaining nut or valve assembly if damaged.

Goal: Verify the successful sealing of the valve assembly
