Mine went AWOL so I came up with this.
Go to your local Home Cheapo and get 1/2" plastic pipe fittings.
I used 90 and 45 elbows. You can use a 90 and straight tube, the 90 is the important one.
I did not glue them, they were a tight enough fit.
For looks you can paint them black or body color.
No more wet, smelly floors during hot weather.
