Just a quick note to say thanks re the pressure switch.

It worked, got it down to 130psi cut off & 85psi cut in.

The differential is a bit wide, would prefer 'bout 100psi cut in, but i'm up and running now so can sort another switch at a later date.

Cheers attitudedesignz there are pressure switches available with adjustable differential, they cost around the $70.00 mark from memory, engineering supply shop should be able to get one for you
