Eljer toilet repair — start by identifying your tank-lid era
Before troubleshooting any Eljer toilet, lift the tank lid and check the underside for the manufacture date stamp and era marking. This determines which parts compatibility class your toilet belongs to and which replacement parts will fit.
Era identification flowchart
| Tank-lid marking | Era | Parts compatibility |
|---|
| "EJ" oval logo (no other markings) | Pre-1968 Independent Eljer | 2-inch flush valve. Most parts custom-order through Mansfield service. |
| "WM" + 4-digit code | 1968-1981 Wallace-Murray | 2-3 inch flush valve mix. Korky 2001BP (2-inch) or 2032BP (3-inch). |
| "HHI" + 091-XXXX | 1981-2004 Household International | 3-inch flush valve standard. Universal Korky 2032BP fits. |
| "Mansfield/Eljer" + 091-XXXX | 2004-present Mansfield-Roca | 3-inch flush valve + Eljer-specific 3-inch shank fill valve. |

Eljer-specific repair gotchas
- 3-inch fill valve shank — DO NOT install Fluidmaster 400A directly. Use 091-7320 OEM, 400UAK adapter, or 528MP universal.
- Wider tank-to-bowl gasket — DO NOT use standard Bemis 7530. Use Eljer 091-7355 or wider universal (Bemis 7560, Korky 463).
- Aqua-Saver II dual-flush cartridge — proprietary Eljer 091-7115 ($45-$60). Korky/Fluidmaster equivalents do NOT fit.
- Triangle (corner toilet) — standard internal parts but tank-to-bowl gasket is specifically corner-pattern (Eljer customer service for replacement).
- Pre-1981 Eljer (Wallace-Murray era) — may use 2-inch flush valves. Verify before purchasing flapper.
- LEFT-HAND THREAD trip lever mount — turn RIGHT to loosen the chrome handle mounting nut.
