What are your symptoms . Why do you think this is a problem . If it drops in a minute or two , there may be something wrong . If you have a pressure gauge checking let it set for a 5 min and see what it does . Most systems will not hold 100% pressure over night . It will loose some and usually is not a problem . What is yours doing .
