House 1 and 2 bathtub drop ceiling

Tub was leaking when filled but okay for showers.

I took the drop ceiling down in the basement to see where it was leaking.

The wedge washer was the problem. It was hard and falling apart.

Replaced and no leaks.

While replacing drop ceiling tiles noticed the light was sagging the tile. the light had been hung on the tile. I added a board to support it.
