"But it has a definite "funk" smell"
Nah, I would've done this different from the beginning.
Nowadays, I always use a solution of silver ion fluid in our tanks
. That stuff works!
It has happpend that I forgot to use the tanks
alternatively only to find out that the STB tank in the aft had been filled 8 months earlier. NO smell at all!
Pure, drinkable water
. Bleech kills only 80 different bakteria types, silver ion over 300.
Before I started to use the silver ion solution we would always carry drinking water
in jerry cans. No longer, now we can use the tank water
for everything comprising cooking
Don't get me wrong, I still have a manual desalinator on board but it's now very unlikely that we'll need it.
A simple solution for potential trouble and no more need for a charcoal filter on board to boot.
OH, yeah, one good and cheap
trick to reduce water consumption
on board is a small needle valve installed in line with the electric
water pump. Tighten it your likings to greatly reduce the water flow @ the faucet. Done.
Just don't tell the crew where that valve is...
