The two ways these fail

Either the drain stops closing, in which case you have a permanent air leak at the bottom of the tank and a compressor that runs far more than it should, or it stops opening, in which case water sits in the receiver and the tank rots from the inside. The second one is the expensive failure, and it is quiet. If you cannot remember the last time you saw your drain discharge, open the manual drain and find out how much water is down there.

What causes it

Condensate off a reciprocating compressor carries oil, rust and scale. That debris is what jams the seat open or plugs the orifice shut. If a drain has failed once on a rusty old receiver it will do it again, so fit a strainer upstream if there is not one already, and blow the drain line through while you have it apart.

Before you order

Confirm the drain on the machine is a Champion Z-TD-1. Compressors get fitted with whatever drain was on the shelf over the years, so the drain currently installed is not always the one the compressor shipped with. The model is usually cast or stamped into the body.
