Frequently Asked Questions
How do I install this RV holding tank?
Installation requires removing your old tank, positioning the new H1107003 tank in the compartment ensuring the end drain aligns with your plumbing, securing with mounting straps, and connecting fittings for drain, vent, and inlet connections. Since this is a blank tank, you'll need to install fittings separately using appropriate hole saws and sealants. We recommend professional installation if you're not experienced with RV plumbing systems.
Is this compatible with my RV model?
This tank fits any RV with a 58" x 28" x 8.5" tank compartment and end drain configuration. Measure your existing tank or compartment space carefully before ordering, paying special attention to drain positioning. Common applications include larger travel trailers, fifth wheels, and motorhomes originally equipped with end drain tanks with these dimensions.
What does "end drain" mean on this tank?
The "end drain" refers to a drain outlet positioned at one end of the tank rather than on the side or bottom. This design is common in many RV configurations and ensures proper drainage when the tank is mounted in specific orientations.
What fittings do I need for installation?
You'll need drain fittings, vent fittings, inlet fittings, and potentially a tank monitor sensor depending on your RV's configuration. Browse our fittings kits or contact us via AI Live Chat with your specific requirements for personalized recommendations.
Can this be used for both black water and gray water?
Yes, this tank is suitable for black water (toilet waste), gray water (sink/shower drainage), or holding tank applications. The high-density polyethylene construction meets health and safety standards for all RV waste storage needs.
What's the difference between this and similar sized tanks?
The key differences are in the exact dimensions and drain positioning. This H1107003 has an end drain at 58" x 28" x 8.5", while similar tanks may have slightly different dimensions or drain positions (end center, side, etc.). Always verify your exact compartment size and drain configuration before ordering.
