Applying Antifreeze to the RV Plumbing System
Before applying antifreeze, it is crucial to identify the appropriate entry point into the RV’s plumbing system. This is typically the freshwater tank’s intake line or a specific bypass valve designed for winterization. Identifying the correct entry point ensures that the antifreeze circulates throughout the plumbing system, providing comprehensive protection against freezing.
The step-by-step process of introducing antifreeze into the RV’s plumbing system involves the following:
- Prepare a sufficient amount of antifreeze suitable for the RV’s water capacity.
- Turn off the RV’s water pump and disconnect the water source.
- Open all faucets inside the RV, including hot and cold water taps.
- Connect a hose or suitable adapter to the chosen entry point for the antifreeze.
- Insert the other end of the hose into a container of antifreeze.
- Turn on the RV’s water pump, allowing it to draw antifreeze from the container.
- Continue running the pump until the antifreeze flows through all faucets, including showers and toilets.
- Repeat the process for external connections, such as an outdoor shower or sprayer.
- Once the antifreeze has circulated through the entire plumbing system, turn off the RV’s water pump and close all faucets.
Ensuring proper distribution and circulation of antifreeze throughout the system is important. You can achieve this by opening each faucet one at a time, starting from the faucet closest to the water pump and moving towards the farthest point. This ensures that antifreeze reaches all areas of the plumbing system, including pipes, valves, and faucets.
Additional Considerations
