As an alternative, you can use Iodophor, which is safe for plumbing materials. It also doesn't have the strong taste which chlorine does. The only downside is it tends to stain plastics yellow/brown, so don't leave any treated water standing in a sink or toilet.
Star San (phosphoric acid - the stuff in Coca-Cola - and dodecylbenzenesulfonic acid - scary name, but non-toxic) is another excellent sanitizer, doesn't stain, leaves no taste. But, if not flushed out, it will foam like soap. But that can be useful, too, for sanitizing the tank. Fill it part way with the proper mix (1 oz/5 gallons), drive around a bit, and the foam in the tank will sanitize the unfilled part of the tank better than relying on other sanitizers splashing around.
