Hello all. Just have to let you know what happened this afternoon. was giving my fathers day gift (bostich brad nailer) some test runs and realized it needed more air . Well I new I could get pressure up to about 120 and the tank was rated at 150. At about 110 psi is when the 20 gal tank split from one end to the other. I dont know how high into the air the compressor went but the hose hit me under the chin. Yes I am ok had i been anywhere else though or if Murphy (big yeller dog) who likes to bark at it, there could have been serious injouries. I have worked on and around large machines for 30 years and know to respect them. So drain your tanks on a regular basis cause i dont think the fellow i got this one from did . Alot of rust inside the tank
