Dual Flow kitchen taps and bath deck mixer

[***Tom11***]

Can anyone advise on makes/models of dual flow mono kitchen mixer taps that work for mixed pressure feed suppies - gravity hot and mains cold ?

Also same for a bath deck mixer ?

I know it can be a pain sometimes finding a tap that doesnt force the cold back through the hot pipe when both taps are opened together.

Thanks in advance.

There are loads of brands, look for a dual flow mixer.

Kitchen tap isnt to much of a problem, struggling a bit for a dual flow bath/shower deck mixer tho

With a deck mixer, the actual valves are not combined, they're at each side, so you should be fine with any deck mixer as the mixed water will come out of the tap spout, water will take the easiest route.
Same goes for kitchen if you get a deck type mixer.

The point of that kind of 'laminar flow' is to stop the mixing and possible contamination as you say. If you fit NRVs in both lines that does the same I believe.

Correct regarding your reasons for fitting NRV's but this will also restrict the flow through the hot so want to avoid installing any

If you would like advice on here might I suggest you give people appropriate information upon which they can off that advice. Otherwise, like I feel now, they will simply not bother. Good luck and I hope someone manages to read your mind in a manner that satisfies you... 🙄

I do think my initial post asking for advice had the relevant information.
I was mearly responding to your comment ref NRV's thats all. Not a case of reading minds !

You won't find a dual flow bath/shower mixer. The purpose of a dual flow is that the hot and cold supplies mix only after exiting the tap outlet. A bath/shower mixer cannot achieve this. Some of these come fitted with built in single check valves which will prevent backflow but for those without them built in, you are required by the water regs to install them on the inlet pipe. Whether this restricts flow or not is irellevent as it's the law.

Franke rotaflow for kitchen tap, nothing equivalent for bath as Riley says. Best off with pair of taps probably.
