1. No screen was evident at the end of the drain tubing. There was no obvious obstruction at the tube inlet.

2. Air flow was noted moving in the direction of the sand cushion.

3. Small stone type particle debris was noted in 10% to 15% of the tube length.

While extensive, it does not appear that these obstructions would impede the flow of water that may come from the sand cushion area.

4. A tubing kink exists at 91 from the tubing inlet

5. A tubing joint was noted at 44 form the tubing inlet and appears to be functional.

6. Overall tube length is approximately 167
