Step 4 · Thoroughly Test for Leaks

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Slowly turn the water supply back on. Meticulously check all connections for any signs of leaks – drips, moisture, or unusual sounds. Address and repair any leaks immediately. A pressure test may be necessary depending on your plumbing system.
