Just did my first Kegging last night filled keg charged up system, checked for leaks with soapy water,set reg at between 9 to 10 PSI,then put in keezer overnight looked this morn. and pressure had dropped to 5 turned to 10 checked about ten hours later and 5 psi again should this be holding steady pressure? Any advice? Also the beer was at about 38 F when put in keg.
