I do drain it most times @spooler but there are some days I'll just leave it pressurized ( 175 psi ) 'cause I know that later on in the day I'll need it again to fill bike tires or what not. Now I'm thinking I don't want to leave it pressurized anytime it's unattended. I have my rec room where my family watches TV right behind that wall ! Ugh... darn it Rusty for putting this in my head...jk.
