Modular Washing Machine Floor Drain

A highly adaptable floor drain engineered for integration with washing machine waste lines in UK homes and apartments. Unit footprint conforms to standard recessed floor drain cut-outs; total mass is 0.8 kg. Housing and internal components are injection-moulded from UV-stabilised PVC for long-term chemical and thermal resistance. The assembly consists of three interlocking pipe sections — tee, bend and straight — plus a threaded sealing cover for full internal access. Dual anti-overflow layers include a positive-action sealing plug and replaceable deodorising cores containing natural zeolite and activated carbon. Self-closing cores operate passively: opening under hydraulic pressure and sealing by spring-assisted reset when dry. Four calibrated silicone rings ensure gas-tight compression against pipe IDs of 32 mm, 38 mm, 40 mm and 46 mm — validated per BS EN 12056-2 for domestic gravity drainage applications. Performance-tested under cyclic load conditions simulating daily washing machine use over 10,000 cycles, confirming consistent sealing integrity and mechanical durability. Ideal for landlords, contractors and self-builders needing future-proof drainage: the modularity supports layout changes during refurbishment, while the sealing cover simplifies annual servicing — no need to break tiles or remove flooring to inspect or clean the trap.
