CPF23400P-2 has watery black discharge
My Porter Cable Model CPF23400P-2 4.0 Gallon 135PSI compressor
My compressor starts to blow a watery black discharge out of the line after it has run for a while.
I have drained the tank 10 times, even leaving the compressor to run for a minute while the drain hole is open, but the problem always comes back.
The discharge is not good inside of my compressed air tools.
Is there a solution to this problem?
