Why Gentworks introduced the GW6 cartridge in 2013

For years, Gentworks has been searching for a cartridge that would deal with the concerns of a significant minority of our customers that have Aridian urinal bowls on site. Prior to the end of successful trials of the GW6, Gentworks tested other solutions which we found addressed some, but not all, of the issues raised by our customers. The other products relied upon a single valve more likely to become stuck in the open position by debris.  Stuck valves allow odours into the washroom. Moreover, the alternative cartridges were intolerant of incompatible cleaning products; a restriction common to almost all waterless urinal designs. If the recommended cleaning regime was not followed, the longevity and function of the cartridge was significantly reduced. Perhaps the unique advantage of the GW6 is its tolerance of cleaning chemicals and water. The double-skirt valve that prevents odours from being emitted into the washroom is the most reliable and robust solution we have come across, giving longer life even when cleaned with standard products. 

In December 2016, the GW6 valve core (Product: GW6V) was further enhanced to increase drainage rate to over 30 litres per minute, by use of a highly innovative air pressure equalisation mechanism. 


About the GW6 valve core - how odours are prevented

The replaceable core (GW6V) of the GW6 cartridge features:

  • dual silicone skirts to prevent odours and backflow
  • pressure equalisation technology to increase drainage rate (from Dec'16)
  • skirt design allows for hair and other small debris to pass through easily, thus maintaining the seal
  • simple screw fitting, only a crosshead screwdriver required
  • easy to clean with water or cleaning chemicals
  • low frequency replacement cycle of a relatively small component, therefore less impact on the environment

How to prevent blockages in waterless urinal waste runs

Gentworks recommends dosing/sluicing urinals fitted with the GW6 valve, approximately once every 2 to 4 weeks, with a solution of Bactericidal Cleaner  mixed with warm water from the washroom hot tap, 

All urinals are prone to blockages, whether waterless or not.  The advantage of waterless urinals over flushed urinals is that there is no limescale from water to combine with urine to form a hard scale. Nevertheless, uric acid crystals and sludge can form, particularly where debris and hair has fallen into the waste pipes and the flow of urine alone has not been able to flush such obstructions away to the main drain. In a washroom with new waste pipes configured perfectly, the flow of urine itself can be sufficient to keep the pipework clear. However, a simple act of preventative maintenance such as dosing/sluicing with Bactericidal Cleaner dramatically reduces the chance of a blockage in all cases.

Gentworks recommends regular dosing/sluicing for all our waterless urinal systems that do not use a liquid seal. For waterless urinals with a liquid seal, sluicing could break the seal and is therefore only recommended during servicing or a cartridge change.
