MultiFlap MF1 ARB1 Anti Cross-Flow and Rodent Barrier Valve for Toilet WC Outlet

Fits most toilets where the waste outlet is behind the toilet Fits directly on to the toilet pan connector Black colouring reduces light from the toilet bowl which is known to attract pests Provides a closed door to rodents in the branch discharge pipe under no-flow conditions Reduces backflow and prevents cross-flow in horizontally-opposed connections The MultiFlap valve remains closed under static conditions and opens when there is flow through the valve, e.g. when the toilet is flushed. The closed valve provides an obstruction for vermin who may attempt to enter the toilet., Manufacturer: Multiflap
