Norvin
To adjust mine I used Dave’s trick. Electricians tape in the bottom of the basket. Forms a 99 percent seal and allows pressure to slowly drop if you put the tape “just right,”
I found my expansion valve was set far too high from the factory. Gave it a clean and some Moly. Think it did the trick. Haven’t had any complaints……. Yet.
Worth swapping to the MK2 just to not have a pressure stat (well, maybe!!)
