Just got a Hill Mk 5 from PA - put it together and tried to fill my gun today and it wouldn’t work. Took almost 50 pumps just to charge the whip to 1000 psi and the handle keeps wanting to pop up. When not connected to the cylinder it pumps easy and air flows out the whip It’s the weekend so I can’t contact PA but I don’t want to take it apart since it’s new. I’ve just been sitting around staring at it lol. Anybody have any similar issues with Mk 5’s..
I reached out to PA this morning. The customer service tech was very friendly and it’s on its way back for replacement. The rep from customer service wasn’t aware of any ongoing issues with new mk5s.
Unfortunately I can also report the same MK5 Issue. Handle rebound and pump doesn't work anymore.Likely gunk clogging up the HP valve and/or/also the little green etc o-rings need to be replaced.The kicker is I bought the pump only 3 months ago and it's already dead :'( In comparison, the MK4 it replaced lasted years until needing a rebuild.Contacted re-seller and will update later ...
