Drill an inch hole in the top and then use a
drip tray with a brass drain tube. Wrap brass drain tube with teflon tape and thread into tray. Place brass drain tube into hole and pack plumbers putty in inch hole surrounding brass tube. Tighten the nut with washer onto the brass threads. Silicone around edge of tray if desired. Use 1/2" vinyl tubing with hose clamp to route waste to a bottle in the kegerator.
