Why Was the EPI 147W Discontinued?
The EPI 147W's unique 48" x 36" x 6" dimensions served a specific niche in the RV market for extra-wide, ultra-low profile applications. Elkhart Plastics has consolidated their product line to focus on more versatile tank configurations. The current alternatives listed above offer similar low-profile designs with comparable capacity and the same FDA-approved construction quality.

Frequently Asked Questions
Can I still order the EPI 147W?
No, the EPI 147W has been discontinued by Elkhart Plastics and is no longer in production. We recommend the W1377000 (43 gallon, 54" x 28" x 7") as the current alternative with the same capacity.
What's the best replacement for the EPI 147W?
The best replacement depends on your space constraints. If you need similar wide width, the EPI 4392 (53.5" x 37.5" x 5.5") is closest but also discontinued. For current production, the W1377000 offers the same 43 gallon capacity in a narrower 28" width configuration.
Will the replacement tanks fit in the same space?
The W1377000 (54" x 28" x 7") is narrower than the EPI 147W (48" x 36" x 6"), so it will fit in spaces with less width clearance. Verify your available dimensions before ordering.
Are the replacement tanks the same quality?
Yes, all current Elkhart Plastics tanks use the same FDA-approved virgin polyethylene, seamless rotomolded construction, and 0.180" wall thickness that made the EPI 147W reliable. You're getting the same OEM-grade quality in current production models.
Do I need the same fittings for the replacement tank?
All alternatives listed are blank tanks without pre-installed fittings, just like the EPI 147W. You can reuse your existing fittings or purchase new ones from our tank fittings collection.
