<p>I just had to buy a new compressor because my 15 year old tank
rusted out. I thought I was pretty good about draining it but
apparently not good enough. Got a whole new compressor for the
price of a replacement tank. New compressor got an hour meter and
an auto drain valve installed before it was even set in place.
Fingers crossed that I won't ever have to buy a new one.</p>
<p>Here is a neat home made idea for a cooler/condenser:

don't drain my tanks as religiously as I should. Too often it
is turn the compressor on, fill a tire, turn it off, leave it
for a month before I have the next tire to fill. Thus I
really want water to not get into my tanks in the first

replace: not the tank.<br>
