Anyone have a similar breakout for a Rocket Mozzafiato type V? I am having almost the exact same issue but it's a vibratory pump. Anyone with any thoughts?

Had the same problem for almost 2 years now but finally had mine serviced after water volume from hot water nozzle went down to almost just a cup which technician said was due to worn out seals. Turns out it was the rotary pump that was causing the pressure problem. It was replaced with a new one. Other seals that needs to be replaced was also done and now works almost brand new. Total cost less than $200. I have a shot counter feature in my grinder and upon checking I probably had over 3000 shots before the pump started showing problems.
