  • Description
    An alternative to the Aquafree UMD, the Cornplastic Urinal Maintenance Device cartridge also dispenses beneficial microbes and other active ingredients over a 3 month period.  The casing, however, is made from renewable energy cornplastic (PLA) conforming to the ISO 14001 standard. The cartridge will completely biodegrade within 1 year, under normal landfill conditions, reducing the impact on the environment.
    Pack sizes:
    Cornplastic replacement cartridges are available in the pack sizes of 1, 4, 12, 24 and 32 units.  Please use the drop down below to select the pack size required. Note that cartridges supplied have a shelf-life of approximately 15 months.
    Optional Waste outlet fitting to act as a receptacle for the cartridge: 38mm (1.5') diameter X 40mm long waste provided as standard, with appropriate backnut and washer.
    (Note: This standard size fits the vast majority of urinals. If in the unlikely event that you order the wrong fitting, please call 0345 202 4535 to receive a free replacement.)
    Pack includes:
    Aquafree Urinal Maintenance Device cartridge designed to dispense beneficial microbes and other active ingredients over a 3 month period.
    (If you do not already have Aquafree or compatible cartridges installed (e.g. UMDs from Gentworks) then please visit  for information about converting to waterless and relevant products.
    Cartridges should be changed every 3 months. To do this, wearing suitable gloves, simply pull vertically the used cartridge out for disposal and insert the new replacement cartridge.  The cartridges reduce the incidence of smells, blockages and, of course, water consumption.  The contents of the cartridge are designed to break down  urine and prevent odours. However, they are not able to break down hair and other debris likely to enter the waste pipes. So, if the cartridges are installed in urinals that are not being flushed, it is essential to "dose" each urinal weeklya very simple task.  For each urinal, mix 100ml of Gentworks Bactericidal Cleaner with  900ml warm water from the washroom hot tap. Pour the resulting 1 litre of diluted solution over and around the head of the cartridge. There is no need to remove the cartridge before doing so.  
    Most odour problems result from poor cleaning practices.  The urinal should be cleaned regularly with Gentworks Bactericidal Cleaner (same dilution as for dosing), Gentworks Bio-Blue or another neutral cleaning product. Cleaning products containing acids, strong alkalis and bleaches must not be used as these will kill the active ingredients contained in the Aquafree cartridge and may lead to odours and blockages.
