Buying Guide: Key Considerations For 10 Gallon RV Water Tanks
What material should you choose?
– BPA-free polyethylene is common and safe for drinking water. It’s lightweight and durable, good for portable RV use.
What fittings do you need?
– Look for tanks with standard NPT fittings (1.5″ and 0.5″ are common) and note their location options. Several tanks offer multiple fitting positions to ease installation in varied RV layouts.
What orientation and dimensions matter?
– Measure the available space in your RV or trailer. Tanks come in different heights and lengths and may be rotated to adjust height or width during installation.
Should you prioritize capacity or space?
– A 10 gallon tank is a balance between space and water supply for short trips. If you need longer trips or more showers, consider a larger option or a second tank.
Are there regulatory or safety considerations?
– Some tanks meet IAPMO or NSF standards, which can be important for potable water storage. Ensure the tank is rated for drinking water if you plan to use it for potable storage.
What about installation ease and durability?
– Tanks described as thicker-walled or built with weather-resistant materials tend to resist wear in rig environments. Built-in fittings reduce the need for additional adapters.
