Buying Guide: Key Considerations for a 10 Gallon Grey Water Tank
- Capacity and space: Confirm that 10 gallons fits your storage area and fits alongside other equipment. Some tanks are longer but narrower, while others are more compact in length but taller.
- Material and safety: Look for BPA-free or NSF-approved plastics for potable or gray water storage, depending on use. Consider products with seamless construction to reduce leak risk.
- Fittings and compatibility: Check the number and size of inlets/outlets. Dual or multiple NPT fittings provide installation flexibility; ensure compatibility with your existing plumbing.
- Orientation and mounting: Some tanks can sit on any side or rotate orientation, which helps in tight spaces. Verify supported orientations before purchase.
- Ventilation and accessories: For portable tanks, a vented cap can help prevent suction and airlock issues. Ensure you have the necessary caps, hoses, and clamps for your setup.
- Durability and warranty: Prioritize high-impact plastics and weather resistance for outdoor RV use. Consider how easy it is to service or replace fittings if needed.
- Installation complexity: Some tanks include more built-in fittings, making installation straightforward; others require additional fittings or adapters.
