I am a german
pumper and start pumping in 1991, with temp breaks.
These pics of a 1 1/2 hour warm-water-pump session from begin to end.
I pump mostly 15 min. dry with low pressure then 30 min. with warm
water
and mid pressure and last 15-30 min. dry with low pressure.
I hope to get lots of mail from (female?) pumpers :-)
