💡 Selection Tip: Choose your tank based on the available space in your RV. The EPI 4580 offers a balanced footprint that works well in most applications. For tighter vertical clearance, consider the low-profile Alpha 207BLANK or EPI 4339. For more compact floor space, the EPI 4733 provides a taller, narrower option.

Manufacturing Note: Sealed Top Hole

You may notice a sealed hole on the top of the tank. This is a normal part of the rotational molding manufacturing process - it's a venting hole used during tank creation and has no functional use for the end-user. This is standard on all rotationally molded tanks and does not affect performance or durability.

Installation Considerations

This blank tank design provides maximum flexibility for custom installations. Professional installation is recommended to ensure proper fitting placement, secure mounting, and leak-free connections. When installing, ensure adequate support across the tank bottom, proper venting, and secure all fittings with appropriate sealants rated for RV holding tank applications.

Black Water vs. Gray Water Applications

This tank is suitable for both black water (toilet waste) and gray water (sink/shower drainage) applications. For black water use, the 3" hub outlet is recommended to handle solid waste efficiently. For gray water applications, either the 3" outlet or the 3" x 1-1/2" reducer outlet works well, with the reducer option providing compatibility with smaller drain lines common in gray water systems.

Frequently Asked Questions

Q: Does this tank come with fittings installed?
A: No, this is a blank tank without pre-installed fittings. This allows you to customize fitting placement for your specific installation. Fittings are available separately and can be added per quote.

Q: What's the difference between the 3" hub outlet and the 3" x 1-1/2" reducer outlet?
