Buying Guide: Key Purchase Considerations For Camper Water Tanks & Pumps
What capacity suits my travel style? Assess typical trip duration, family size, and water usage to choose between 5–50 gallons. For extended trips or larger RVs, a 35–50 gallon tank is often ideal. For solo travelers or compact vans, 5–15 gallons can suffice.
Is a pump kit included or separate? Many sets include a 12V on-demand pump and a basic plumbing kit. If not, plan for a compatible 12V pump and essential fittings. Consider pumps with adjustable pressure and dry-run protection for reliability on the go.
What fittings and ports are needed? Look for at least two 1.5″ NPT ports for easy plumbing, plus 0.5″ ports for smaller connections. Confirm the valve and hose compatibility with your hose fittings and clamps.
Is the tank pressurized or non-pressurized? Non-pressurized tanks require venting and gravity filling, while some setups allow for a pressurized line. Pressurized tanks can offer quicker fill but require careful installation to prevent leaks or tank damage.
Material and safety certifications? NSF-approved materials indicate suitability for drinking water. Confirm compliance with local codes and IAPMO standards for durability and hygiene.
Space and mounting considerations? Measure storage area and consider tank orientation flexibility since many tanks can rotate to fit different dimensions. Check for clearance around fittings and access for maintenance.
Maintenance and durability? Tanks made from weather- and impact-resistant polyethylene tend to last longer on the road. A thicker wall compared to OEM options can improve longevity in rough conditions.
Additional Tips For RV Water Systems
- Avoid sealing garden hoses directly to tanks to prevent pressure buildup and potential rupture.
- Use gravity filling with a proper fill dish when venting is required.
- Keep a spare set of fittings and clamps for roadside adjustments.
