Upgrade your plumbing system with McAlpine's Self Closing Waste Valves, showcasing the cutting-edge MacValve membrane. Designed to open under water pressure for efficient discharge and promptly close to form a reliable seal, these waste valves prevent foul odors and sewer gas from entering your building.
One of the key advantages of MacValve is its flexibility in installation—it can be fitted horizontally or vertically, providing versatility for various plumbing setups. Unlike traditional valves, MacValve eliminates the risk of drying out through evaporation or lack of appliance use, ensuring consistent performance.
MacValve is ideal for installations where a non-return valve can enhance plumbing efficiency. Additionally, it can be used to handle the discharge from a pressure relief valve on an unvented domestic hot water storage system, following guidance notes in approved Document G3 of the Building Regulations.
However, it's essential to note that MacValve must not be used for baths or shower trays unless there is access for maintenance. When installed as part of D2 Pipework from an unvented appliance, MacValve must be positioned vertically in accordance with Building Regulation G3.
