$2 Fix to a $1,000 Problem

After observing the location of the hole in the pictures, I decided to try to access the hole from beneath the bracket. I fashioned a tool out of 5/32 brass tubing and .080 weed whacker line.

I took a 12" length of the tubing and bent a radius about an inch from one end. To prevent the tube from crimping, I inserted an awl and slowly pulled the awl out while bending the tube.

I inserted a three foot length of the weed whacker line and melted the end at the radius to prevent it from pulling back through the tube. It also helps to clean the drain hole.

Slide the tool under the mounting bracket and gently rotate the end downward so that when it catches the hole it falls into place.

Feed the line through slowly, working it up and down as you go, to help clean the hole. When the line moves freely, your drain should be open and water should be able to pass through freely.

I've created a short video to demonstrate the process.
