Fresh Water Holding Tank Replacement for Heartland RV Model #14069

An exact replacement for the reported Heartland 14069 / vendor W1163 tank has not been verified. The old answer's claim that the original is obsolete is unsupported by the current evidence. Treat the reported part numbers and 55-inch length, 30-inch width and 7-inch depth as identification leads to check against the original tank label and manufacturer drawing.

ICON's WT3594 manufacturer reference lists 55 x 24 x 7 inches and nominal 38 US gallons. Its listed width is 6 inches less than the reported 30 inches. Matching length and height does not establish a direct replacement, acceptable mounting or compatible plumbing.

The current WT3594 catalog listing, native SKU 14374, is an identification reference only. Its “.5 inch fittings” wording refers to connection size, not proof of five supplied fittings. ICON distinguishes tank-only, generic fitted and coach-specific configurations; confirm the exact current supplied configuration and drawing rather than transferring one version's openings or sensors to another.

Before selecting a replacement, verify the complete tank identity/revision, outside envelope, mounting and support, fill/vent/drain positions, connection types and any sensors or other attachments. A tank-finder result or a coach name is only a research lead. Current availability, delivered price and shipping must be checked for the identified item; no order, stock or delivery promise is established by this historical answer.
