Key Features and Benefits
Seamless Rotomolded Construction
Unlike welded or seamed tanks that can develop leaks over time, this Elkhart Plastics tank features one-piece rotomolded construction. This manufacturing process creates a seamless, uniform wall thickness throughout the entire tank, eliminating weak points and ensuring long-term reliability even under the stress of road vibration and temperature fluctuations.
Premium 0.180 Inch Wall Thickness
The heavy-duty 0.180" wall thickness provides superior strength and durability compared to thinner-walled competitors. This robust construction resists punctures, cracks, and deformation, ensuring your tank maintains its integrity for years of reliable service.
Compact Dimensions for Tight Spaces
Measuring 40" × 14" × 11", this tank is specifically designed to fit into the tight spaces common in RV construction. The elongated profile makes it ideal for installation under beds, in storage compartments, or in narrow chassis spaces where traditional square tanks won't fit.
Efficient 3 Inch Drain Fitting
The 3-inch drain fitting ensures fast, complete emptying at dump stations. Larger than standard 1.5" or 2" drains, the 3-inch opening reduces dumping time and helps prevent clogs from solid waste materials.
Blank Tank Design for Custom Installations
This blank tank configuration gives you complete flexibility to add fittings, sensors, and vents exactly where you need them for your specific installation. Whether you're doing a direct replacement or a custom build, you control the final configuration.
Chemical and Odor Resistant Material
The black polyethylene material is specifically formulated to resist the harsh chemicals used in RV waste treatment systems. It won't degrade, crack, or absorb odors over time, maintaining a sanitary and odor-free system.
Compatible Applications and Use Cases
RV Black Water Systems
Perfect for toilet waste storage in travel trailers, fifth wheels, motorhomes, and camper vans. The 19-gallon capacity provides adequate storage for weekend trips or as a secondary tank in larger systems.
RV Gray Water Systems
Ideal for collecting sink, shower, and washing machine drainage. The chemical-resistant construction handles detergents, soaps, and cleaning products without degradation.
RV Restoration Projects
When restoring vintage RVs or replacing failed original equipment, this OEM-quality Elkhart Plastics tank provides a reliable, long-lasting solution that meets or exceeds original specifications.
Custom RV Builds
For DIY RV conversions, van builds, and custom trailer projects, this blank tank gives you the flexibility to create a waste system tailored to your specific layout and needs.
Marine and Portable Applications
While designed for RVs, this tank is also suitable for marine heads, portable toilet systems, and off-grid cabin installations where reliable waste storage is needed.
Installation Guidance
This holding tank should be installed in a secure, level location with adequate support underneath. Use appropriate mounting straps or brackets to prevent movement during travel. Ensure proper venting to prevent vacuum lock during draining and to allow gases to escape safely. Install a gate valve on the drain fitting for controlled emptying at dump stations.
For custom installations, you'll need to drill and install fittings for the inlet (from toilet or drains), vent pipe, and any sensors or monitoring equipment. Use appropriate sealants rated for waste system applications to ensure leak-free connections.
Health, Safety, and Quality Standards
Elkhart Plastics manufactures this holding tank to meet rigorous industry standards for RV waste systems. The polyethylene material is NSF-approved for waste water applications and meets RVIA (Recreational Vehicle Industry Association) standards for RV holding tanks. The seamless construction and heavy wall thickness exceed minimum safety requirements, providing peace of mind for you and your family.

Frequently Asked Questions
What is the difference between a black water and gray water holding tank?
This tank can be used for either application. Black water tanks store toilet waste, while gray water tanks collect sink and shower drainage. The tank itself is identical - the difference is in what you connect to it and how you label it in your system.
Does this tank come with fittings installed?

How do I know if this tank will fit my RV?
Measure your available space carefully, accounting for clearance around the tank for fittings and hoses. This tank measures 40" × 14" × 11". If you're replacing an existing tank, compare these dimensions to your current tank. If you're doing a custom installation, ensure you have adequate space plus room for connections.
Is this tank suitable for marine applications?
Yes, while designed for RVs, this tank is suitable for marine waste systems, portable toilets, and off-grid applications. The chemical-resistant polyethylene construction handles marine waste treatment chemicals effectively.
