Emptying your RV's fresh water tank is a crucial part of RV maintenance and ensures the longevity of your system. Failing to do so properly can lead to bacterial growth, foul odors, and potential damage to your plumbing. This guide will walk you through the process step-by-step, covering various scenarios and addressing common questions.
Understanding Your RV's Fresh Water System
Before diving into the emptying process, it's essential to understand your RV's fresh water system. Most RVs have a low-point drain system, making the process relatively straightforward. This system typically consists of valves located at the lowest points of your water tank and plumbing lines. Locate these valves – they are usually easily accessible under the RV, near the water tank.
Step-by-Step Guide to Emptying Your RV's Fresh Water Tank
-
Turn off the water pump: This is crucial to prevent water from being continuously pumped into the tank while you're trying to empty it. Locate your water pump switch (usually inside the RV near your plumbing panel) and turn it OFF.
-
Open the low-point drains: Locate the low-point drains for your fresh water tank (usually two, one on each side or near the bottom). These are typically valves that you turn clockwise to close and counterclockwise to open. Open these valves completely to allow water to drain freely.
-
Open the drain valve on your fresh water tank: This valve is usually located on the outside of your RV, near the fresh water tank. Open this valve completely to allow all water to drain from the tank.
-
Check for complete drainage: Allow ample time for the water to drain completely. You should observe a steady flow of water initially, which will slow as the tank empties.
-
Close the drain valves: Once the water has completely drained, close all the drain valves by turning them clockwise.
-
Flush the system (optional but recommended): After emptying the tank, it's highly recommended to flush the system with a solution of water and bleach to kill any remaining bacteria. Use a mixture of one cup of bleach per gallon of water. Fill your fresh water tank with this solution, then let it circulate through your system for about 30 minutes. Afterwards, thoroughly flush the system with clean water.
How Often Should You Empty Your RV Fresh Water Tank?
The frequency of emptying your fresh water tank depends on several factors, including the duration of your RV trip and your personal preferences. Generally, it's recommended to empty your tank every 3-5 days, or more frequently in warmer climates to prevent bacterial growth. Emptying the tank after each trip is also good practice.
What if My RV Doesn't Have Low-Point Drains?
Some older RVs may not have a low-point drain system. In this case, you'll likely need to use a gravity drain valve located at the bottom of your fresh water tank. Open this valve and allow the water to drain. This process might be slower than using low-point drains.
How to Winterize Your RV Fresh Water System
This is a crucial step for anyone storing their RV during colder months. Winterizing prevents water from freezing and damaging your pipes. The process typically involves using RV antifreeze to flush the system and replace the water. Consult your RV's owner's manual for specific instructions on winterizing.
What if My Fresh Water Tank Won't Empty Completely?
If your fresh water tank isn't emptying completely, there could be several reasons:
- Clogged drain valve: Check the drain valve for any debris that might be obstructing the flow.
- Debris in the drain line: A buildup of sediment or debris in the drain line can restrict water flow.
- Frozen drain valve (in cold weather): If the weather is cold, the drain valve might be frozen. Try thawing it before attempting to drain the tank.
If the problem persists, consult a professional RV technician for assistance.
This guide provides a comprehensive overview of how to empty your RV's fresh water tank. Remember to always consult your RV's owner's manual for specific instructions and safety guidelines. Regular maintenance of your fresh water system will ensure a safe and enjoyable RV experience.
