I see alot of new parts to the alpha 170 -200 and up..the impeller the nozzle on the pump etc..i bought mine over 2 years ago and didn't have those upgrades at the time how can i get my units up to date? especially the 170 with the push pull type of nose if it gets bumped there goes my perfect setting ...now they have the screw type adjuster that seems better? well any input is appreciated.
