Thanks, I'll give that a go tonight and see if that helps.
Just couldn't seem to get it to foam better last night.
Ended up changing the DC controller to max in the end tried a few different things, even dropping it down to 9, but nothing seemed to work well. Maybe the head height and something to do with that as you say so will turn down the little twisty valve to try and lower it some and see how that gets on.
Even played with the little screw in the air thing but that seems to be more of a fine tune thing from what I gathered.
