I wasn't clear enough.
The article was specifically about eliminating the bad taste
of water from
the fresh water tank after winterization with RV anti-freeze. The article
was from the "Mark, My Words" column of the March/April 2014 Escapees
De-winterization is a task that will be coming up for me (and others?)
fairly soon. The article said that the "taste" may be coming from
the water tank or even from residue of the anti-freeze in your fresh
The recommendation was:
Drain your fresh water tank. Then, for tanks of under 40 gallons, add
one gallon of plain white vinegar (Heinz apparently makes a white
"cleaning vinegar"). Use the manual or electric pump to get the
white vinegar into and through the pipes and coming out of the faucet(s).
Allow things sit overnight (or at least several hours). Then drain the
tank and fill and flush with fresh water. If the vinegar flush is done
immediately after removing/flushing the RV antifreeze, it usually
kills the taste and odor. (Credit: Escapees magazine).
In addition, it said that you might consider installing an under-sink
charcoal filter to filter out tastes and impurities.
We've now purchased an external filter (Camco - although there may
be better?) that we will use to filter the water going into our city water
inlet or to use on the hose that we fill the fresh water tank with when
we are camping without a city water hook-up.
