To use the Thetford 36662 Fresh Water Holding Tank Sanitizer Kit effectively, first bypass the water heater by closing the valves directing water into and out of the heater and opening the bypass valve, if available. Next, sanitize the fresh water tank and lines by following the kit's instructions, ensuring the sanitizing solution runs through all cold water faucets and outlets. After the recommended contact time, flush the system thoroughly by repeatedly filling the tank with clean water and running it through the lines until no bleach odor remains. Finally, re-engage the water heater by reverting the bypass valves to allow water flow through it once again. This ensures your RV’s freshwater system is clean and ready for use.
