Underfloor – Window Tubes

Use tubing to direct water outside the structure in the event of a window leak.

Install the tubing at the lowest point of each window sill.

Use cable clamps and tee fittings to connect and secure the tubing. Link the tubing from each window sill to ensure water flows downward.

Run the tubing through the wall bulkhead and out the bottom.

Terminate the tubing into a catch to monitor for window leaks. Two Gatorade bottles were used, one for each set of windows.
