The water heater started leaking, the hydrofor started leaking, the pipes had several dead ends, no of it fastened to the walls, and what's not clear in the 1st picture is the complete mess at the pump.
New water heater, new hydropress, pipes mounted to the walls, re-routed electricity. Re-used what I could, but much is new. My pride: I could not get a flens that fitted the pump (yeah, an industrial one of twice the price of a similar jetpump). I found I could remove the flens and fit a coupling I have in a box for over 30 years and survived 3 moves. Removing it was exciting, it had been in place for 40+ years but I managed without damaging the cast irons pump housing.
There is still some 'floating' pipes to fix, but over 95% of the job is done. Man, did that improve the water flow !!!
As far as I know they are quite maintenance-free, and did not notice anything needing attention or love
Out of curiosity I took out the primer bolt and had a look. There is a back-valve so there is no need for that. Priming is no big deal. Make sure the system is not pressurized (you don't want the bolt being shot into your face, nor flood the floor). Take out the bolt, fill with water to the brim, replace the bolt and you're good to go.
Thank you!
