Frequently Asked Questions

What's the difference between a black water and gray water holding tank?
Both use the same tank construction. Black water tanks collect toilet waste; gray water tanks collect sink and shower water. The EPI 4733 can serve either application — the designation depends on how you plumb it.

Can I add my own fittings to this blank tank?
Yes. The blank configuration lets you drill and install fittings exactly where your RV's plumbing requires. Work with your RV technician or contact us via AI Live Chat for guidance on fitting options.

Will the 26.5" x 20.5" x 17.5" dimensions fit my RV?
Measure your available bay space carefully — length, width, and height. If you need help confirming fitment, our AI Live Chat can assist with compatibility questions.

Is this tank made in the USA?
Yes. Elkhart Plastics manufactures these tanks domestically using American materials and processes.

How thick are the walls on the EPI 4733?
The walls are 0.180" thick throughout the entire tank — uniform from top to bottom, providing consistent strength and impact resistance.

Is this the same tank used by RV manufacturers?
Yes. Elkhart Plastics supplies OEM-grade tanks to RV manufacturers. The EPI 4733 is the same quality part used in original factory builds.
