I've just had a 20 psi pressure drop overnight. 1500-0800. It's a cold room with a 50m run. 3/4 and 1/2 inch pipe. 30m is outside. Liquid line is not lagged.
Solenoid valve is open and OFN was added into high and low side.
I couldn't find a leak and the pressure hadn't dropped in the 4 hours I was there. Could there have been any pressure equalisation (?) or is it possible the 7 degree temperature drop would have an effect?
Merry Christmas
