You could install a flow switch between the pressure vessel and
the rest of the plumbing, wired so when it detects flow, it turns
the pump on (So in parallel with the current pressure switch).

This way, the pump will always run when you are running water, and
only turn off when the pressure has reached the setting of the
pressure switch and there is no water flowing out of the pressure
vessel. I have this setup with my irrigation system setup, it
seems to work
well for me!

I had considered a flow switch but could only find information on
little laboratory systems - we have 1.25" PVC pipework. It would be
easy to fit if I can find one! I'll have to go to the shops on
Wednesday - a 3 day holiday out here for the new year!

Crikey, that's HUGE! we use that sort of pipe for the waste out of
the bath!!

Why is it so big - is it supplying a lot of people/apartments?

And a pump only costs £50.

Supplying 14 appartments.

Prices are reasonable - but then plumbers only get about £5 a day.

When in the UK I can not believe the prices. On example, flexible hoses 20p
each, screwfix £1.75. Who keeps this profit?

Thanks for all the advice, I now feel confident to go out again and sort the
problem.
