Where's the water filter that needs cleaning. Also for som reason the water out let for setting the mixing level seems to be full of crap after every spray . I never had this with the g4 ! Am I doing somet wrong. ( set float level the atatch pipe to mixing zone top one. Set level and put cap back on once water has stop completely . Prime r&s then just check level hasn't dropped by opening cap and pressing water till it comes out again n replace once stoped. StArt motor n add powder. Once I've got right mix stop motor. Atatch pipe n airline turn on comp then motor then spray away
