PhilD said:It's not essential to have a pressure gauge to do the pressure mod. You can instead measure the amount of water dispensed through the OPV return in a given time and refer that to Ulka's pressure/flow graph for the pump model you have to work out its approximate setting.
Easier than I've probably made it sound. I'll let you do the googling but let me know if you can't find the method and I'll see if I can find it.
It is easier and I did this initially but it was 1-2 bar out when I actually used a meter.
