Fitting the Neoperl FLP device has significantly reduced the noise of using our bathroom taps. Since we changed to a pressurised hot water tank, the additional pressure supplied to the taps around the house has lead a combination of more noise and too much flow. After installing the 4 litre/minute FLP device in the bathroom taps we noticed a real reduction in noise and a perfectly manageable flow to wash and brush teeth with. Also we have noticed that if someone is in the shower, turning on the tap does not change the shower temperature which is a bonus.
