TN 10317 - HepVo self-sealing waste valve

TN 10317 - HepVo self-sealing waste valve

OSMA

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.
TN 10318 - Air admittance valve

TN 10318 - Air admittance valve

OSMA

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 10319 - Recreational vehicles

TN 10319 - Recreational vehicles

OSMA

Drainage systems in recreational vehicles such as caravans, coaches, buses, motorhomes and boats have issues with water seal traps because of movement and potential infrequent use. The use of water seal traps in these circumstances may cause the water seal to be lost or to evaporate over time, allowing odours to escape from the waste system into the vehicle.
TN 10320 - Hot climates and infrequent use

TN 10320 - Hot climates and infrequent use

OSMA

The HepVO ® self-sealing valve uses an elastomeric membrane to create the odour seal and therefore there is no water/sealing fluid that may evaporate or deteriorate that may compromise the seal. The features and benefits listed in Technical Note TN10317 for the application of the HepVO ® valve in the domestic environment also apply to the installation of the self-sealing valve in hot climatic conditions.
TN 10321 - Condensate drainage and unvented hot water systems

TN 10321 - Condensate drainage and unvented hot water systems

OSMA

In the UK, the use of a temperature relief valves or combined temperature and pressure relief valves is mandatory for unvented hot water storage system in excess of 15 litres and also used on some vented hot water storage systems. These valves can discharge at 96?C (BS EN 1490:2011). However, discharges from pressure-only relief valves without temperature control will discharge at over 100?C. The HepVO ® self-sealing valve can be fitted to the discharge of unvented hot water storage systems, primary thermal heat stores and heat interface units allowing them to be connected directly to sanitary pipework provided they are fitted with a temperature relief valve or combined temperature and pressure relief valve.
