Made to a high specification in Italy, the Osmio Mariella is a very high quality 3 Way Triflow Kitchen Mixer Tap in Chrome finish. It is also available in Brushed Nickel finish (pictured above). Please note that there may be a 10 day + lead time (depending on stock availability) for the Matt Chrome and Brushed Nickel finishes.

The Osmio Mariella makes the ideal solution for a 3 in 1 kitchen mixer tap by combining elegant design and superb functionality. The Osmio Mariella would be a welcome addition to a top quality home or workplace kitchen and uses separate water paths to ensure that the filtered water pathway is not mixed with any unfiltered water.

On the right hand side, there is a mixer lever for hot and cold with the lever for filtered water on the left. The build quality of the Osmio Mariella 3 Way Triflow Tap is second to none with a very heavy solid brass construction with a durable highly polished chrome, matt chrome or brushed nickel surface.

The full kit comes complete with flexible hoses and fitting parts. We offer a wide range of very high quality water filter systems you can purchase along with this stunningly elegant, modern and top quality 3 way triflow kitchen mixer tap.

How the Tap Handles Work

The diagram below shows how the tap handles work. The right hand lever pushes out and moves away from you for hot water and towards you for cold water and anywhere between mixes hot and cold. The left hand lever will move towards you and provide the filtered water - or if you are using a water softener and your cold and hot side is softened, you can have this side providing the hard water for drinking, which can be filtered or not as you prefer.

Dimensions & Technical Drawing

Filter System

✔ Granular Activated Carbon (GAC) – for chlorine, taste and odour reduction

✔ Phosphate – for scale inhibition

✔ De-alk resin – for temporary hardness and heavy metal reduction

The Watts 2.5 x 10 GAC/Phosphate & De-Alk Filter incorporates granular activated carbon (GAC) which is combined with Phosphate and De-alk resin. The filter is effective against chlorine, taste and odour, heavy metals e.g. lead, and will also tackle hard water, which is seen as limescale in kettles and as an unsightly scum on the surface of hot drinks. Water hardness varies greatly depending upon location, so the filter will need to be replaced at 3 - 6 monthly intervals or longer all of which entirely depends on the hardness of your water and the amount you use.

We recommend your flow rate not exceed 4 LPM for the best contact time and filtration.

Water Pressure & Flow Chart

This tap will produce the following flow rates according to the incoming pressure on both hot and cold:

0.5 bar - 0.4L/M / 0.5 bar - 0.4L/M
1.0 bar - 3.0L/M / 1.0 bar - 1.0L/M
1.5 bar - 4.8L/M / 1.5 bar - 5.2L/M
2.0 bar - 6.0L/M / 2.0 bar - 6.4L/M
2.5 bar - 6.8L/M / 2.5 bar - 6.8L/M

It is therefore recommended that this tap only be used on a pressurized hot water system. It may be used on a gravity fed hot water system provided the incoming pressure produces a flow rate that is acceptable to you, or if the gravity fed hot water system is pumped and pressurized.
