So, I bought this 8 gallon Kobalt air compressor new about 5 years ago.  Humid Houston air has not been kind to the tank.  My not relieving the tank after each use also hasn’t been kind.

Today I opened the valve.  And yup, rusty water blew out…

AI seems to think this Kobalt can last 10-15 years (with regular maintenance) and “occasional” use.  Is it likely to develop a small leak or pin holes or will it just go kaboom one day?

It still seems solid at this point.   No leaks or visible damage.  I don’t know if any maintenance or rust removal can be done???  Remove the valve and swish around some Evapo-Rust or Ospho??

Shame on me for not draining it after each use.  It’s been a great little compressor doing everything I need it for.  Mostly tires and occasionally running an impact driver to remove big stubborn nuts and bolts.

I'm just crossing my fingers.  I think it's ok for now.  I got a good deal on this one at Lowes.  Keep an eye open for a sale.
