These snap-on snap-off urinal caps are quick and easy to install and then replace. They combat the risk of blocked pipework by breaking down the uric acid that may build up over time. The deodorising caps contain naturally occurring bacteria that also combat the bacteria that cause unpleasant odours helping to maintain hygiene levels and a fresh-smelling washroom environment. Cleaning and maintenance is also made easier as less water reduces the build-up of lime-scale deposits.
