What is an RV Propane Water Heater Bypass?
An RV propane water heater bypass is a critical feature that prevents water from entering the heater’s tank, specifically useful during winterization. When the bypass is engaged, water flows around the water heater rather than filling it, effectively preventing freezing and subsequent damage during cold months.
Failure to properly manage this bypass can lead to contamination of your potable water supply with antifreeze, ultimately causing costly repairs and inconvenience when you’re ready to utilize your RV in the warmer months.
Components of the Bypass System
The bypass system typically includes two main valves and associated plumbing. These valves direct the flow of water either through the heater or around it, depending on the season.
Understanding these components is crucial:
- Bypass Valves: These valves can either allow water to flow through the heater (for use) or divert it around the heater (for winterization).
- Water Heater Tank: Where the water is heated before being distributed throughout the RV.
Importance of Bypassing During Winterization
Bypassing during winterization is essential for protecting your RV water heater from freezing temperatures. Freezing can lead to cracked tanks and damaged pipes, resulting in expensive repairs.
The bypass ensures that antifreeze used during the winterization process does not enter the boiler, safeguarding your drinking water supply.
- Bypassing prevents water from entering the heater, crucial for winterization.
- Proper use of bypass valves protects against freezing damage.
- Contamination of the potable water supply can be avoided with careful management.
How to Set Up RV Water Heater Bypass Valves
Setting up the RV water heater bypass valves correctly is fundamental, especially when winterizing your RV. Generally, two valves control the water’s path: one directs water into the heater, while the other diverts it around.
Knowing how to identify and operate these valves can help you avoid contamination and ensure proper winterization.
Identifying the Bypass Valves
To determine the state of your bypass valves, locate them, usually found behind the water heater access panel or in a compartment near the water system connections. Typically, the valve handles will indicate the flow direction.
When preparing for winter, ensure to rotate the handles to align them horizontally, indicating that water will bypass the heater.
Steps to Set Valves for Use and Bypass
Follow these steps to set up your RV water heater bypass valves:
- Locate the bypass valves and identify their current position.
- For winterization, turn both valves to align horizontally, diverting water around the tank.
