Fresh Tank Drain

Fresh Tank Drains in RVs

The fresh tank in your RV holds the supply of clean water you use for showers, sinks, and faucets. Draining the fresh tank is important for several reasons:

• Winterization: To prevent water lines and the tank from freezing and potentially cracking during cold weather, you'll need to drain the fresh tank completely before storing your RV.

• Sanitization: Regular cleaning and sanitization of your fresh tank helps prevent mold, mildew, and bacteria growth. Draining the tank is a necessary step before proper cleaning and sanitization procedures.

• Moving to a New Location: If you're moving your RV to a location with a new freshwater source, you may want to drain the existing water in the tank to avoid potential contamination or taste issues.

Here's a breakdown of how fresh tank drains typically function in RVs:

• Location: The fresh tank drain is usually located on the underside of your RV, often near the axle or towards the rear. It may be behind a panel or access door for protection from the elements.

• Drain Valve: A valve controls the opening and closing of the drain outlet. The most common types are:

Gate Valve:

A manual lever that slides open or closed to allow draining.

Ball Valve:

A rotating handle that opens and closes the valve. May be a lever or a wheel-like handle.
