Description

Feature / Aspect	Why It Matters / What to Check
Compatibility with Cistern Model / Flush Valve	Ensure the extension matches the flush‑pipe diameter and connection type of your cistern model (e.g. AV1 valve type, overflow pipe size etc.)
Pipe / Extension Length	Pick an extension length that provides enough reach so the flush outlet/waste line lines up correctly with toilet pan and drainage — too short or too long may cause misalignment or leaks.
Seal & Waterproofing / Waste‑pipe Seal	Ensure that seals, gaskets or connectors are used as required — to avoid leaks when extending the flush/waste pipe.
Compliance with WC Frame / Mounting Structure	For concealed or wall‑hung WCs, the extension should fit within the frame or mounting system (or be compatible).
Ease of Installation / Retrofit Use	Good extension kits allow retrofit without major wall modifications — helpful if upgrading or replacing an existing cistern.
Durability & Material Quality	Use a high-quality, compatible extension (like genuine Grohe part) to avoid premature wear, cracking or leaks over time.
Maintenance / Access	Ensure the extension doesn’t block maintenance access (inspection shaft etc.) or interfere with flush‑plate / actuator set‑up.
