RE: PS groaning

[Aleksander Mierzwa <alex@matrix.com.pl>]

I'm not 100% sure and the search engine is down, but I think there should be
a plastic restrictor in the pressure hose. If you still have the old hose,
you may look inside to see if there's one. Most likely the new hose came
without the restrictor and this causes the vibration - you are feeling the
pressure pulses from the pump.
