TN 10318 - Air admittance valve


Where branch pipes are long or steep, negative pressures can develop in the system which can cause loss of seal in water seal traps by self siphonage. EN 12056-2, Table 6 and Approved Document H1, Diagram 3 give guidance on when provision of branch pipe ventilation is required. This is traditionally by provision of a water seal trap incorporating an AAV. Where HepVO ® is used in place of a water seal trap there is no further need for a branch air admittance valve for venting protection at that appliance. The HepVO ® will only allow air to enter the systems and will prevent backflow of air from the stack.

TN 10317 - HepVo self-sealing waste valve


HepVO ® is a self-sealing waste valve for use as an alternative to a traditional water seal trap, in particular where a water seal trap is not suitable, for example, due to climate, movement of the appliance or because of infrequent use. Its in-line design and the option of either horizontal or vertical installation can save space. The valve can also reduce the requirement for additional venting of some appliances. HepVO ® is made of a polypropylene body with an elastomeric membrane, in the form of a self-flattening tube, acting as a selfsealing valve. The self-closing membrane prevents foul air from drainage systems from entering the building and also acts as an insect barrier.
