Step 8 · 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.

This is the most critical step. Slowly turn both water shutoff valves back on by turning them counter-clockwise. Watch all four connection points (two on the washer, two on the wall) closely for any signs of water. Use a dry paper towel or your hand to feel around each connection to detect any slow drips that might not be immediately visible. If you find a leak, turn the water off immediately and tighten the leaking connection slightly (about an eighth of a turn), then test again. Do not proceed until all connections are completely dry.
