A separate waterway, and a filter you keep buying · review
GRIFEMA three-way brass kitchen mixer with three 50 cm DVGW hoses review
A brass three-way mixer that arrives with all three hoses certified and both filter threads in the box — the least ambiguous first installation in this hub.
The bottom line The three-way tap that removes the connection guesswork: three certified hoses, both threads, all fixings. It publishes nothing at all about its own shape.
What you are getting
A three-way kitchen mixer with a brass body, stainless fittings and a chrome finish, with two levers, three DVGW-certified 50 cm hoses — hot, cold and drinking — and both 3/8 in and 1/4 in filter connections.
Why the box matters more than usual here
A three-way tap fails at its connections, not at its spout. Three hoses instead of two, a filter thread that has to match, and a drinking-water line that has to be certified for the job. This listing states all three hoses at 50 cm, all three certified, and both threads supplied.
That is the most common reason a three-way installation stalls, removed before it starts.
What the tap does not tell you
Its shape. No outlet height, no reach, no deck bore. If anything sits above your sink, this listing will not settle whether the tap fits.
And the filter is still separate
No cartridge is included. The filter housing, its cartridge and its replacement interval are the real running cost, and they are a separate decision from the tap.

What we like, and what we don't
Strengths
All three hoses are 50 cm and DVGW-certified, including the drinking-water line — stated individually
Both 3/8 in and 1/4 in filter connections supplied, so most filter systems connect without an adapter
A brass body with stainless fittings and chrome, and a picture-based installation guide with all fixings
Compromises
No dimension published at all — no height, no reach, no deck bore
Nothing said about the cartridges, on a tap with two of them
Sold as an Amazon exclusive, which is worth knowing if you compare prices elsewhere

Questions people actually ask
Why does the drinking-water hose need certifying too?
Because it carries the water you drink, and it is the line people forget. This listing states DVGW certification on all three hoses individually, including that one.
Will it connect to my filter?
Both 3/8 in and 1/4 in fittings are supplied, which covers most under-sink systems. Check which your filter uses before ordering — it is written on the housing or in its manual.
Three-way kitchen mixer · three separate internal lines · own lever for filtered water · 304 stainless · cold-start lever
A two-lever three-way tap that states what actually distinguishes this family: three separate internal waterways, so filtered water never shares a channel with the mixed side.
Best for: Replacing an existing single-hole kitchen tap with one that also serves an under-sink filter, without cutting the worktop.
Three-way kitchen mixer · 320 mm outlet height · 280 mm spout · G3/8 and G1/4 filter connections · hole 35–38 mm · brass core on the filtered side
The best-dimensioned kitchen tap in this catalogue: an outlet height, a spout length, two filter thread sizes, a deck bore range and a worktop limit, all published.
Best for: A large single or double sink where filtered water is wanted and the tap has to be checked against the worktop before anything is drilled.
A basin mixer supplied with a solid brass rod waste and a cartridge the maker states has passed 500 000 cycles — the tap on this page that arrives most complete.
Best for: Replacing a tap and a tired waste at the same time, on a basin that has an overflow.
