I really need help. (Hopefully with a Herbie style drain)

Thanks, looks simple enough.

"I would say get rid of this cap and put on one with a single 1/4" piece of hose that you can adjust up or down, and if that does not work you might want to look at changing some of your plumbing Sphelps way."

Last question, how do you mount the single 1/4" piece of hose that you can adjust up or down. Do you just drill a hole in a cap and insert the hose?

Thank you all for all your help
