Choosing Your 100 Gallon RV Fresh Water Tank: Types and Considerations
Selecting the right 100 gallon RV fresh water tank requires careful thought. It’s not a one-size-fits-all decision, as various factors will influence the best choice for your specific rig and travel style. This section serves as your essential 100 gallon RV fresh water tank guide.
Material Matters: Polyethylene is King
Most RV fresh water tanks are made from food-grade polyethylene. This material is:
- Durable: It resists impacts and cracks, crucial for off-road travel.

Use thread sealant or Teflon tape on all threaded connections to prevent leaks. Double-check all connections before filling the tank.
Sustainable Water Management: 100 Gallon RV Fresh Water Tank Best Practices
Having a large water tank is fantastic, but managing it sustainably is even better. Implementing smart strategies ensures you maximize your supply and minimize your environmental impact. This section focuses on sustainable 100 gallon rv fresh water tank and eco-friendly 100 gallon rv fresh water tank approaches.
Sourcing and Filtering Your Water
Not all water sources are equal. Be mindful where you fill up:
- Approved Sources: Stick to potable water sources like RV parks, municipal campgrounds, and designated water stations.
- Water Filters: Always use an external water filter when filling your tank. A multi-stage filter can remove sediment, chlorine, and even some bacteria, improving taste and safety.
- Emergency Sourcing: For truly remote situations, consider a portable water filter or purifier (like a Berkey or Sawyer filter) for drawing water from natural sources. Treat it as a last resort and purify thoroughly.
Remember, your 100 gallon RV fresh water tank is only as good as the water you put into it.
Daily Conservation Techniques
Even with 100 gallons, smart conservation extends your adventures:
- Low-Flow Fixtures: Install low-flow showerheads and aerators on faucets.
- “Navy Showers”: Wet down, turn off water, lather, rinse quickly.
- Efficient Dishwashing: Use a minimal amount of water, perhaps a spray bottle for rinsing, or wipe dishes clean before a quick wash.
- Grey Water Management: Understand that conserving fresh water also impacts your grey water tank. Plan for proper disposal.
These 100 gallon rv fresh water tank tips are crucial for maximizing your independence.
Maintaining Your 100 Gallon RV Fresh Water Tank: Care and Troubleshooting
Proper maintenance is paramount for the longevity of your tank and the safety of your water supply. Neglecting care can lead to unpleasant tastes, odors, or even health risks. This section provides a comprehensive 100 gallon rv fresh water tank care guide and addresses common problems with 100 gallon rv fresh water tank systems.
Cleaning and Sanitizing Your Tank
Regular sanitization prevents bacterial growth and keeps your water fresh:
- Frequency: Sanitize at least once a year, or more often if water sits for long periods or develops an odor.
- Process:
- Drain the tank completely.
- Mix 1/4 cup of household bleach (unscented, 5-6% sodium hypochlorite) for every 15 gallons of tank capacity. For a 100-gallon tank, this is about 1.5 – 2 cups.
- Pour the solution into the fresh water tank.
- Fill the tank completely with fresh water.
- Run water through all faucets (hot and cold), shower, and toilet until you smell bleach.
- Let the solution sit for at least 4 hours, or overnight for best results.
- Drain the entire system.
- Refill the tank with fresh water and flush all lines until the bleach smell is gone. You may need to refill and drain several times.
Consider using a non-toxic RV fresh water tank sanitizer for an alternative to bleach.
Winterization Procedures
If you live in a cold climate, winterizing is non-negotiable to prevent costly damage:
- Drain Completely: Empty your 100 gallon RV fresh water tank and all water lines. Open all low-point drains.
- Bypass Water Heater: Ensure your water heater is bypassed before adding antifreeze.
- Pump Antifreeze: Use RV-specific, non-toxic antifreeze. Pump it through all water lines until it comes out of every faucet.
- Don’t Forget the Toilet: Pour some antifreeze into the toilet bowl to protect the seal.
A frozen tank or burst pipe can quickly ruin your adventure.
Common Problems and Troubleshooting
Even with the best care, issues can arise:
- Foul Odor/Taste: Usually indicates bacterial growth. Sanitize the tank immediately. Check your water filter.
- Low Water Pressure: Could be a failing water pump, clogged filter, or air in the lines. Check connections and filters first.
- Leaks: Inspect all fittings, hoses, and the tank itself. Small cracks in polyethylene can sometimes be repaired with specialized plastic welding kits, but severe damage may require replacement.
- Water Level Sensor Malfunctions: Sensors can get coated with mineral deposits, leading to inaccurate readings. Cleaning or replacing them may be necessary.
Addressing these issues promptly ensures your 100 gallon rv fresh water tank system remains reliable.

- Bottled Water: Keep a small reserve of bottled water for emergencies or when you’re unsure of your tank water quality.
These practices, combined with your large tank, ensure you have clean water for all your needs.
Frequently Asked Questions About Your 100 Gallon RV Fresh Water Tank
How long does 100 gallons of water last in an RV?
This varies significantly based on usage. For a single person practicing moderate conservation, 100 gallons could last 10-14 days. For two people, 5-7 days. With strict conservation, you can extend this further. Factors like shower frequency, dishwashing habits, and toilet flushing all play a role.
Is a 100-gallon tank too heavy for my RV?
A 100-gallon tank full of water weighs approximately 834 pounds (plus the weight of the tank itself). You MUST check your RV’s Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Ratings (GAWR), and overall cargo carrying capacity (CCC). Exceeding these limits is dangerous and illegal. Always calculate the total weight of your water, gear, and passengers.
