Solutions/Water saving at the outlet
Solution A · water and energy saving

Tens of per cent less water at every outlet.

Aerators and flow regulators on basins and showers cut both the water and the energy used to heat it — and stay comfortable even at low pressure. German engineering by R.C. Mannesmann.

Two types of stream from a tap outlet side by side — aerated on the left, laminar on the right
How it works

Less water, the same comfort

The regulator keeps the stream and the pressure pleasant while letting less water through. Less water also means a lower heating bill.

01

Constant flow

A steady stream even as pressure varies in multi-storey buildings — without spitting.

02

Comfort even at low pressure

An aerated or a laminar stream, whichever the setting needs; the user does not notice the change.

03

Easy maintenance

Limescale prevention and a replaceable core simplify cleaning and servicing.
