Remember though when it comes to pump pressures you have to allow for the head pressure coming from the source. Hi Thanks for the link - Just downloaded and will study .... Yes .... Head pressure + pump pressure = Gauge pressure When I get back to Thailand again I will bring with me a pressure gauge ( 0 t0 10 bar) Thanks Fruit Trader - Just what I wanted to do when in Thailand last time - but I ran out of time .. Valve was installed .. but could not lay my hand on the gauge. The pump will stop under two conditions - max pump pressure (whatever the pressure switch setting is or no flow (i.e. flow sensor and pressure switch wires go into the motor control PCB) Will post an update when I get to the bottom of this ..
