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

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

Just drill it so it is a bit tight and has a bit of friction.
It should be about 3"-4" long and just push it in until the noise stops.
If it restricts the water too much pull it up a bit.
Just make sure to cut the top of the tupe off at the max water height in case it plugs up. To see what happens when it plugs up just test it by putting your finger on top.
