Thank you Darren for taking the time for me I appreciate it,I know I’m going to have to open it up tomorrow at some point but I didn’t want to do anything until I’ve called them and tbh I really tried to get the top off and it wouldn’t budge.
I did lift the cap like I said and I didn’t see any O ring that should be under the cap and compressing onto the metal houseing but it hasn’t leaked before that’s the dilemma for me,should it come off without removing stainless fittings that’s what I’d like to know there’s either a hell of a lot of pressure inside or it’s attached,the ionic RO they demo on YouTube is so simple to maintain takes 2 minutes to change.
