Description
Product Overview
The Class A Customs 24‑gallon black water tank is engineered for RVs, campers and travel trailers. Constructed from medium density polyethylene (MDPE) resin, the tank resists impact, UV exposure and chemical corrosion. Its rectangular profile maximizes capacity while fitting into narrow compartments. The tank includes a factory‑installed 3‑inch ABS female outlet, ready for connection to your waste‑dump system. Dimensions and weight are optimized for easy handling and secure mounting.
Usage
Designed for waste and gray‑water storage, this tank is ideal for long‑distance road trips, weekend getaways, and full‑time RV living. It integrates seamlessly with standard RV plumbing, allowing you to connect PVC or ABS piping to the outlet. The tank must be vented and paired with appropriate inlet and dump‑valve hardware (not included). Suitable for both residential‑type RVs and larger travel trailers, it provides reliable performance in varied climates.
