What is the best way to determine if your pool liner leaking?

Step 1: Visual Inspection:

- Check the liner for any visible tears, punctures, or cracks. Look carefully around the seams, corners, and areas where the liner meets the pool walls and stairs.

Step 2: Water Level Test:

- Mark the current water level on the pool's interior wall with a pencil or marker.

- Wait 24 hours without using the pool or adding water.

- Check the water level again. If it has dropped significantly, there might be a leak.

Step 3: Dye Test:

- Purchase a pool leak detection dye kit.

- Add the dye to the pool water according to the kit instructions.

- Circulate the water using the pool's pump.

- Look for areas where the dye concentrates or forms a trail, as these may indicate leaks.

Step 4: Pressure Test:

- Disconnect the pool's automatic water filler and attach a pressure gauge to the hose connection.

- Close all valves and turn on the water supply.

- The pressure should rise steadily. If it drops or fluctuates significantly, there could be a leak.

Step 5: Underwater Inspection:

- If possible, use goggles to look for leaks underwater.

- Check the pool's seams and corners, especially around steps and lights.

Step 6: Hire a Professional:

- If you suspect a leak but can't locate it, consider hiring a pool professional to diagnose and fix the issue.

Remember, if you suspect a pool liner leak, it's important to address it promptly to prevent further damage and water loss.
