Buying Guide: How To Choose The Right RV Fresh Water Tank
What capacity do you need?
Assess your typical trip length and refill accessibility. Smaller tanks (10–20 gallons) fit compact RVs and day trips, while 20–30 gallon tanks fit mid-sized RVs for longer excursions between fills.
Is the material safe for potable water?
Look for BPA-free polyethylene or NSF-approved plastics. These materials reduce the risk of chemical leaching and support safe drinking water storage.
How important are fittings and installation options?
Tanks with multiple built-in fittings or standardized NPT ports offer flexible mounting in tight spaces. Confirm the availability of recommended fittings and whether a separate plumbing kit is needed.
Should you prefer a tank with a complete kit?
Some options include plumbing kits or pumps, which can simplify installation. If you want a turnkey solution, those models can save time and reduce the risk of missing components.
Maintenance and care considerations
Regularly flush and sanitize tanks that store drinking water to prevent taste or odor issues. Tanks with accessible drain or vent features can simplify routine maintenance and long-term hygiene.
Portability vs. durability
Rotational-molded or blow-molded tanks offer different balance points between weight, strength, and price. Consider how often the tank will be moved or jostled during travel.
