Grohe kitchen tap

[Macru77]

I need to fit a grohe tap but my current connectors are a different size.

Current tap is connected directly to a flat end isolation valve. See pic.

Does anyone know of any connectors that are available so I can connect the grohe tap without removing the currently fitted flat end isolation valve so if I switch back to a standard tap in the future it’s no hassle.

They don't look like flat ended ISO valves, even then you may want to change the ISO around while you're at it so the arrow points in the direction of the flow.

(edit)- Are the Grohe ends smaller - typical Euro sized feeds are 3/8" not 1/2" like the UK.

As above use the reducers but you will need a couple of nuts and olives if they are the correct size. You do get female to male adapters that would go right on the end of the ISO like these could be used.
