Doug,
Been there... done the following....
Replace all the Vinyl hoses
If possible Hand scrub the inside of the tank ( I installed a large inspection
port in the top of the tank).
Wash and Rinse with the following ..
Oxi-clean or any Carbonate Cleaning product... ( for years I've tried to
convince boat owners to use the Cleaner used in Beer and Wine making.Some them
don't even need to be rinsed away.... But it's hard to change the thinking of
some)..
If you need to sterilize the tank... You can use Wine/Beer sulfate tablets or
powder.
Check the Yellow Pages for a Wine/Beer making supply store..
Most folks recommend BLEACH.. but the smell stays in the hoses and I hate that
Chlorine stink.
But, Some folks swear by it.. If you do use it.. use a SMALL amount and rinse
it many times.
I personally never used Chlorine bleach chemicals in my boat's drinking water
supply.
If you can't Hand scrub.. Fill the tank to FULL with the Cleaning solution and
allow it to Slosh around for a couple days .. then rinse out..
IF you do use a Chlorine Bleach .. Buy a BRITTA filter pitcher and use that
water for all drinking.. Britta removes most of the Chlorine smell/taste..
Good luck ...and.... UW
