how often to replace popoff valve on air compressor?

[zxcvbob]

The relief valve on my big air compressor goes off every time I fill it (the compressor is maybe 10 years old).  And it doesn't shut off until the tank is almost drained.
The valve on my small compressor has recently started doing that too, before it reaches the 150 PSI where the pressure switch cuts off.  That one is maybe 5 or 6 years old.  I'm tempted to remove the valves and put in plugs but I know that's a bad idea; there should always be a back up safety.

Should this be a routine maintenance item?  Can the relief valves be adjusted and can I safely do that myself?

Check you cut offs I have replace several of those but not a pop off on an air compressor. If cut off's are working then replace the pop off valve. Don't even mess with the old ones.

Replace them when they start failing. They aren't "regular" maintenance, but they do fail.

Definitely don't put plugs in.

Pop off valves are usully a simple screw in affair. Replacement is a five minute fix unless it's integrated into the pressure switch.

Sometimes pressure switches are adjustable. Might be able to lower the cutoff pressure to just under the popoff valve's limit as a short-term fix.
