[Shop-talk] Buying a new compressor of just the 'compressor'?

[Jack Brooks]

Thoughts on compressor longevity; When I changed out the anode in my hot
water heater ( you all do this every 5-10 years right?) the new one was a
tad long to clear the ceiling, so I trimmed off about 6 inches..  I dropped
that 6 inch section into my compressor tank (horizontal cylinder) about 10
years ago.  I hope it is doing its job.

BTW - Really, you should be changing your water heater anodes every 5-10
years.

Even here in relatively dry southern California, my last (cheap) compressor
tank rusted through and started leaking before the compressor packed it in.
At one point I also had the pressure control switch malfunction and leave
the compressor running; plus the pop-off valve didn't do it's job
(apparently full of wasp's nest).  Probably lucky it didn't explode, but the
single stage compressor would only go so high.  The PRV sure screamed a long
time after I touched it, though!  So if you're looking to go another
20 years, my suggestion would be to replace all of it.

Ingersoll-Rand is the "gold standard" for air compressors IMO.  I'd find an
IR model that suits your needs and go with that.  The one I use was made by
IR, but sold by Sears.  It's probably 20 years old by now (I bought it used)
and still going strong, but I don't use it all that much.
