Here are the facts:
Bleach can actually damage rubber or plastic components (including new hose fittings) by causing them to break down quickly. It can also ruin or clog up filters and strainers. And, bleach breaks down rapidly in water, so it degrades faster than many other sanitizers.
In the winter, some RVers use bleach in their water bladder tanks to keep the water from freezing. But RVers should never use bleach as a substitute for antifreeze. The reason is that the bleach breaks down rapidly and leaves harmful residue behind. Conversely, antifreeze keeps working and doesn’t leave any residue in your lines or tanks when it finally freezes.

Avoid using the following types of bleach in your RV’s plumbing and holding tank:
- Hot bleach. In hot bleach, the chlorine gas is separated from the water. However, removing all of the chlorine from a hot bleach solution weakens it considerably. By the time it reaches your water tanks and lines, there will only be about a third of the original strength left.
- Cold-process or warm (not hot) bleach. Because of the way that bacteria function, warm bleach is not as safe as hot bleach.
