Hi,
If the water is tasting funky I would definitely check the filter or clean any components of the cooler. You want to start with something that is safe, sanitary and fresh. Marie doesn't speak about the hexagrams in relation to charging water and food as much as she does with the Dowsing rings. She mentions in the Dowsing course about using the small or medium ring to generate and amplify positive energy. Check out the Dowsing forum for more info too.
All the best,
Kat
