Why Was the EPI 184H Discontinued?
The EPI 184H's specific 22.75" x 15" x 7.5" dimensions served a niche in the compact RV market, but Elkhart Plastics has consolidated their product line to focus on more versatile tank configurations. The current alternatives listed above offer similar compact designs with comparable capacity and the same professional-grade construction quality.
Finding the Right Replacement Tank
When selecting a replacement for the discontinued EPI 184H, measure your available space carefully and prioritize your most critical dimension:
- Need same 12 gallon capacity? The Alpha 261BLANK (20.75" x 16" x 9") delivers identical capacity in a similar compact footprint
- Need low-profile under 8"? The EPI 184H's 7.5" height is hard to match - most current tanks are 9" or taller
- Willing to accept less capacity? The EPI 450H (9 gallon, 22.5" x 16.5" x 9") offers similar dimensions with 3 gallons less

Frequently Asked Questions
Can I still order the EPI 184H?
No, the EPI 184H was discontinued in July 2022 and is no longer in production. We recommend the Alpha 261BLANK (12 gallon, 20.75" x 16" x 9") as the closest current alternative with the same capacity.
What's the best replacement for the EPI 184H?
The Alpha 261BLANK offers the same 12 gallon capacity in a similar compact footprint (20.75" x 16" x 9"). It's slightly wider and taller than the EPI 184H but maintains the compact design for small RVs.
Will the replacement tanks fit in the same space?
The Alpha 261BLANK (20.75" x 16" x 9") is slightly shorter in length but wider and taller than the EPI 184H (22.75" x 15" x 7.5"). Verify your available clearance, especially height, before ordering.
Are the replacement tanks the same quality?
Yes, both Elkhart Plastics and Alpha tanks use professional-grade polyethylene, seamless rotomolded construction, and heavy-duty wall thickness. You're getting the same OEM-grade quality in current production models.
Do I need different fittings for the replacement tank?
Replacement tanks are blank tanks without pre-installed fittings, just like the EPI 184H. You can reuse your existing fittings or purchase new ones from our tank fittings collection.
