If you spot a leak:

1. Immediately shut off the water supply.
2. Carefully tighten the connection in question.
3. Repeat the slow reintroduction of water and visual inspection.

The Dry Paper Test: A Detail-Oriented Approach

For added confidence, employ the dry paper test. This involves dabbing a clean, dry paper towel or tissue around each connection. Even a minuscule leak will leave a damp spot on the paper.

This method is particularly useful for detecting slow, subtle leaks that might be missed during a visual inspection. It's a simple but highly effective way to ensure a watertight seal.

Verifying Adequate Water Pressure

Once you're confident that all connections are leak-free, it's time to check the water pressure. This is crucial for ensuring that your refrigerator's ice maker and water dispenser function properly.

Open the water dispenser on your refrigerator and observe the water flow. Is the stream strong and steady, or is it weak and sputtering?

Similarly, check the ice maker. Does it produce ice at a normal rate? If the water pressure is insufficient, you may experience slow ice production or a weak water stream.

If you suspect low water pressure, double-check that the main water supply valve is fully open. Also, inspect the water line for any kinks or obstructions that might be restricting the flow. If problems persist, a plumber might be needed to evaluate the supply pressure.
