Aerators – one of the most important components of every faucet Nowadays , aerators can be found on the spouts of virtually all washbasin and bathtub faucets .
They shape the water to produce a nonsplashing stream and add air to make the water pleasantly soft . They also reduce plumbing noise and help to save water and energy .
Flow regulators ensure that a defined , virtually constant flow rate is maintained , regardless of pressure fluctuations . They are used in faucets , in instantaneous water heaters and in solenoid valves . You can use flow regulators to reduce water consumption – they offer costeffective solutions in the wide spectrum of technical applications .
Check valves protect faucets and installation systems to prevent the backflow , backpressure or backsiphonage of used water into the pipeline system . They also guard against the potentially hazardous crossover flow between hot and cold systems in thermostatic faucets , for example . This means that hot water cannot get into the cold water pipe or vice versa .
