be²re you blame the cooK. It might
be your water trailer.
³yeball the inside of thE tanK. If it's
fibErglass, taKe a close look at the
enamel coating. The coating cracKs as

Water gets in the cracKs and touches
the ´iberglass hull. It's the fiberglass
that gives your co±ee that sweAty-µEt
flavor.
If a cracK is big enough to see, it's
big enougH to make good water taste
bad.
¶ave your DS recoat the tank
using the instructions in TM 9-2320-
267·14&P.
ClEaning the tanK also improves the
taste of your co±ee. THe TM says clean
it annually or when the medics say tHe
tanK is contaminated. But wHy wait¸
