MacValve Dry Trap 1 1/4

Product Description


MacValve - 1 1/4" BSP Female Inlet Nut x 1 1/4" Universal Compression Outlet.

MacValve Self - Closing Waste Valve
  • Can be fitted in horizontal or vertical position.
  • MacValve membrane opens under water pressure to allow discharge to flow freely and then closes to form a seal to prevent foul odor or sewer gas entering the building.
  • MacValve can be fitted in installations where a non-return valve can be of benefit to the plumbing installation.
  • MacValve can be used to take the discharge from a pressure relief valve on an unvented domestic hot water storage system. Please refer to guidance notes in approved Document G3 of the Building Regulations.
  • MacValve having no water seal can never dry out through evaporation or lack of use of an appliance as the membrane remains sealed.
  • MacValve is not recommended for the use with shower trays unless there is access for maintenance.  
 
WHEN MACVALVE-1 AND MACVALVE-2 ARE INSTALED HORIZONTALLY THE FLOW ARROW MUST BE IN THE UPPERMOST POSITION
