Fiamma aqua 8 water pump

[terrychef]

Hi everyone, we have a Fiat Ducato Mclouis, with a Fiamma aqua 8 water pump that will not switch off. I have striped it down and cleaned it up, the pressure switch is clicking (manually) but not automatically with the pressure. Any help would be great, many thanks. Terry.

Hello and welcome to the forum.

I'm afraid I can't give any advice, but I'm sure someone else will be able to.

Some pumps are adjustable with small screw or Allen key on the top.

As jev88 said. The screw doesn't adjust the pressure, that's set at factory, but it adjusts the pressure the switch operates at.
It will need adjusting until the pump just stops. Then open a tap and close again to see that the pump starts and stops
If not it needs finer adjustment.

Hi jev88, I have adjusted the screw fully in and fully out, still not switching off. Many thanks.
