Buying Guide
What capacity do you need? For tight mobile spaces, 26–50 gallons may suffice; for longer jobs or larger crews, 57–100 gallons offer fewer refills. Material matters: high-density polyethylene resists rust and UV exposure, making it suitable for outdoor detailing. Look for molded gallon/liter graduations to monitor volume without opening the tank. Check fittings: NPT standard sizes (1.5″ and 0.5″) and bulkhead options influence compatibility with pumps and hoses. Consider portability: square, rotomolded tanks balance stability with space efficiency. If you require potable water, prioritize NSF/BPA-free materials and proper certifications.
