How low should I tune it?Give it at least two weeks so it breaks in , this is normal, try and tune it down so the water level is a bit lower
So basically take the knob out and how about the water flow should I open that all the way?Having the air and water restriction open the entire way and give it a couple weeks. Then slowly start adjustment.
I did it lastnight and tonight the foam is dirty so I guess it working it just has to foam to the top now.Don't take the knob the whole way out. Good way to loose it... Just keep it open as much as possible for both the air and water. Then slowly adjust it every several days a small bit.
