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

Looks like I could try it one of 2 ways.

First I could put a piece of 1/4" hose on the top, but how do you attach 1/4" hose to a piece of 1 1/2" PVC pipe so that it is adjustable? This sounds like it could be the simplest cure.

Secondly I could turn my 1 1/2" drain into a "Herbie" with a gate valve and use one of the return holes for the emergency drain, leaving me with one hole for returns. The tank currently has 1 - 2 3/4" hole for 1 1/2" drain and 2 - 1 3/4" holes for 1" returns.

I'm not sure I understand why one needs an emergency drain for the Herbie style, but not for the Durso.

Oh my, sometimes I wonder why I started this? (Just silently venting)
