The products covered by this EPD are concealed (in-wall) WC cisterns designed for residential and commercial sanitary installations. They are self-contained plastic assemblies that store and discharge water into the toilet bowl via an internal mechanical flush mechanism.

The series includes fifteen functionally equivalent variants — 8050452871, 8050453003, T02-0111, T02-2113, T07B-5113PK43-0272, 7030452911, F2-0053-0030, 8050452712, T02-0140, T04-5113-0256, T05-0140-0251, T06-5113-0251, T06-0130-0240, F5-0053-0252, and T03-C113B-0041 — manufactured by Fluidmaster Türkiye at its Tuzla–İstanbul facility.

Each cistern consists primarily of injection-moulded thermoplastics (PP, HDPE, ABS, POM) with elastomeric seals (EPDM/Silicone), metallic components (galvanized or stainless steel, brass inserts), and optional EPS/EPP insulation liners. The declared unit is 1 piece of cistern with a nominal mass of 5.83 kg (model-dependent).

All variants listed below are manufactured at the same facility using the same production steps. Model-specific differences relate to bill-of-materials quantities, component geometry, and total product mass, as documented in Annex/Table [1]. No further interpretation of similarity or significance is provided.In accordance with PCR 2019:14 (v2.0.1) – Construction Products, this EPD represents a multi-product average based on a representative configuration (Model T02-0111). Other models fall within the permitted variation range (±10 % mass or impact deviation) and are included under this declaration.
