Incorporates a self-closing membrane which opens to allow discharge to flow freely and then closes to form a seal. Membrane seal creates no resistance, ensuring smooth discharge flow from the PRV/TRV, and is spring-free, so not affected in hard water areas. Prevents foul odour or sewer gas entering the building when installed into a waste or soil pipe. If required the top tundish window can be removed from the Mactun body for inspection or cleaning when maintenance work is being carried out.
