Model number: wdb18005the mc alpine 1 plastic basin space saver is a compact waste trap for basin installations, fitted with a self-closing membrane valve in place of a conventional water seal. The valve seals shut between uses to hold back drain odours, and because it doesn't rely on standing water, it can't dry out or lose its seal through evaporation or infrequent use. At just 58.2Mm high and 130.4Mm wide, it's designed for basins where a standard trap has nowhere to go. Made from durable white plastic and tested to bs en 1451-1 bs en 1329-1, it connects via a 1 bsp female inlet nut and a 1 universal compression outlet. The valve also admits air into the waste pipe under negative pressure, removing the need for secondary ventilation. It's easy to clean in place: remove the split pin, take out the plug and membrane, wash in hot soapy water and reassemble. It's a practical retrofit for basins with restricted pipework space, and a like-for-like swap wherever a full-depth trap won't sit. Key features:self-closing membrane valve
