Alpha System RV Waste Holding Tank | VB24637HLJ | 40 Gal | HDPE

Replace your RV holding tank with the Alpha System Waste Holding Tank (Part #VB24637HLJ). 40-gallon capacity permanently-installed waste holding tank — usable for either black OR grey water depending on your installation needs. High-density polyethylene (HDPE) construction, low-profile 7" height, left-hand side drain location. Backed by 1-year manufacturer warranty.

⭐ Dual-Use — Black OR Grey Water

Meaningful versatility: this tank can be used for either black or grey water applications. Same tank, same construction — the difference is which waste system you plumb it into.

⭐ 40-Gallon Capacity — Substantial Holding Volume

Meaningful capacity for extended RV use:

• 40-gallon capacity — substantial holding volume
• Fewer dump station trips during extended stays
• Meaningful supplement for RV builds or replacements needing larger holding capacity

⭐ Low-Profile 7" Height

Standout dimensional feature: at just 7" tall, this tank fits installation locations where taller tanks won't. Meaningful for:

• Under-floor installations with limited vertical clearance
• Between-frame mounting in low-clearance chassis
• Custom RV builds with space constraints

High-Density Polyethylene Construction

Standout durability: high-density polyethylene (HDPE) construction:

• Chemical resistance — handles waste, cleaning chemicals, and holding tank treatments
• Long-term durability — HDPE is the industry standard for RV holding tanks
• Impact-resistant — handles road vibration and terrain

Left-Hand Side Drain Location

Important fitment detail: drain located on the left-hand side. Verify your intended installation layout supports left-side drain routing before ordering.
