Backflow is always a risk in water pipes and backflow protection must always be used to prevent the water from becoming contaminated. Taps with a hose  connection are particularly vulnerable. If backflow occurs in a garden hose when watering the lawn or washing the car, contaminated water could flow back into the water system and spread to other taps and buildings.
Durgo has a wide range of taps with a built-in checkvalve and vacuum valve preventing backflow.
