I bought an old Quincy QR 25 model 216 compressor off a friend.
It was used for over 30 years in his father's dry cleaning shop, then made it to his shop..and now mine... Got it installed and working...it runs continuously and cycles the compressor on when it needs more pressure in the tank. This compressor was made in 1962, and the tank is dated 1961. Should I be concerned about the integrity of the tank? |

Quoted:
what color is the water that comes out when you drain it? The drain valve was plugged with rust and crap...had to clean it out... Not much water came out of the tank. Every air compressor tank that I have ever drained has had rusty colored water, so it didn't concern me too much. |
| You can pull a valve and do a visual inspection, but I can guaranty there is rust on the inside. There is no required testing for a low pressure tank that I know of. I have had compressors tanks that have been in service for over 50 years with no leaks. When I have seen a leak, it has always been a pin hole leak. If you get a leak in the tank, then take it out of service. It really all depends on the installation and maintenance as to how long they last. |
| I personally would stab the shit out of the bottom of it with a screwdriver to see if I can poke through. they have been known to blow, but the only affects I have seen from one blowing is loud noise and a lot of dust. The particular tank was on a welding truck bolted underneath the body, so when it went off, it kicked up all the dirt from the spot it was parked at. Honestly thought the truck exploded for about 10 seconds. |

I've seen the results of two blow ups in home garages. A man was killed in one. The damage to the structure and contents was remarkable. |

Just had a 19 year old craftsman one that was my dads detonate on me. Enough to move a 300lb rear blade for a tractor, blow out the ply wood wall and pull the nails out of my work bench that was built into the 6x6s of my barn.
2 safety release valves failed and the regulator failed too. Honestly. I consider it a one in a million event. Just check your relief valves and it should be good to go. |
| if your really worried about it just buy a new tank maybe even upgrade to a bigger tank if it suits your needs better THIS is a place we get tanks from at work but its not the only place that sells tanks |

The air compressor my dad and I used for about 30 years developed a pinhole leak in the tank as well. It just went HISSSSSSS!!!!! No explosion. If it's in a garage that is unattended, I heard it is a good idea to keep it unplugged when not in use, that way if a leak develops the compressor won't keep running until it burns the garage down. |

It's going to be switched off unless it's in use.... |

Well...
Turns out there IS a pinhole leak. It's on the outer weld where the drain petcock threads in. I can feel it with my fingers and when I spray some cleaner on it, I can make it bubble. Where do I get a top quality American made tank of the same configuration? This looks to be an 80 gallon tank, from what I can guess..
