Frequently Asked Questions
How do I install fittings on this blank RV holding tank?
This blank tank allows you to drill and install fittings exactly where you need them for your specific RV layout. We recommend using a hole saw for clean cuts and proper tank fittings with rubber gaskets and sealant rated for waste applications. Our AI Live Chat can provide detailed fitting recommendations based on your installation needs.
Is this tank suitable for black water or gray water use?
Yes, this 32 gallon holding tank works perfectly for both black water (toilet waste) and gray water (sink/shower drainage) applications. The chemical-resistant polyethylene construction handles waste treatment chemicals and cleaning products without degradation.
What's the difference between rotomolded and welded RV holding tanks?
Rotomolded tanks like this one are formed from a single piece of plastic with no seams or welds, eliminating weak points that can crack or leak. Welded tanks have seams that can fail over time, especially with temperature changes and road vibration. Rotomolded construction provides superior durability and leak resistance.
Will this 40x20x12 holding tank fit my RV?
This tank fits most mid-sized RVs, travel trailers, and motorhomes with standard compartment dimensions. Measure your available space carefully, allowing extra room for fittings, sensors, and installation clearance. The 12-inch height works well in compartments with moderate vertical clearance.
Can I add tank level sensors to this blank holding tank?
Absolutely. The blank configuration lets you install sensors at optimal locations for accurate readings. You can use traditional probe-style sensors or external ultrasonic sensors depending on your preference. Contact us for sensor recommendations compatible with this tank.
What's the warranty on this Elkhart Plastics holding tank?
