Sanitizing Water Tank

I think the question has not been answered. When filling the fresh water tank "how long can it sit before needing to have chlorine added" is what I believe the question is.

Slight hijack. From my time river rafting, where we filter and treat our own water right form the river, I have found many people object to the chlorine taste/odor after sanitizing the water with bleach. A friend of mine, a chemistry professor, told me that after using the bleach and waiting for the appropriate amount of contact time we could add an identical amount of hydrogen peroxide and that would counteract the bleach. No odor, no taste and pretty good water. Just a thought.

I have repeated this cycle for 11 years with no problems. Yes, I do drink the water from the tank.

X2 Been doing this for 40+ years without any issues, and we use the water in the tank for everything except coffee. We bring water from home for that.

I have heard anything from 2 weeks (hot weather), to 30 days...

If you use the "standard" dilution of 1/4 cup bleach per 15 gal of holding tank capacity (~ 50ppm), then it should sit for at least 4 hours. Leaving it sit longer won't hurt anything.

If you use a 100ppm concentration (or 1/2 cup per 15 gal), then at least 1 hour.
