New kitchen tap connectors too small

[jmskippy]

We bought a new Grohe kitchen tap, it came with flexible connectors but the end which screws onto the valve is too small. The old flexi tap connector was 22mm and the new is smaller, probably 15mm. I have tried to get and adaptor to no avail. The valve end where the connector connects to is just a bit of thread.
If anyone can understand what I am talking about, any advice would be much appreciated.

I have been to B&Q, Wickes, Homebase, Screwfix and Builder Depot.
A guy at Builder Depot was very helpful and gave me something, it's a connector with a 15mm side to fit the new connector and the other side 22mm with a nut and copper washer. He said I would need some copper piping for that and then something on the valve side.

Again, if anyone has experienced this, please help.

Thanks

Toolstation product 63663 will fit inside a standard compression fitting and bobs your uncle

could possibly be 3/8 European size. toolstation do adaptors as above but 3/8 not 1/2 on the threaded end

Grohe will be 3/8th as Steve said above. Used to be a pain , but carry a pair of 15mm to 3/8th male irons just for this purpose.

Most Grohe taps are 3/8 thread. You will need a 3/8 male iron to 15 mm compression, a short peice of 15mm copper and a fitting from 22mm down to 15mm. It might be 1/2 inch thread so you would need a fitting from 22mm reducing to 1/2 BSP thread.

Or even easier option, call a plumber and save your time and patience :daisy:

Thanks, this sounds good.
Just so that I understand correctly...
I insert the non threaded bit into the valve. Don't I need some kind of seal between the valve and the pipe?

Thanks

Thanks to everyone for your replies.
Long story short...We had our bathrooms redecorated last month and the guy who did it, also our neighbour who we often socialise with, offered to change the tap as a favour. He started the job on Saturday and encountered the problem but had other stuff to do so didn't come back to us. That's when I tried sorting it out. When I eventually got the spares which you all kindly helped me with the guy had come back and put some piping and other bits in. Much effort wasted but like I said, thanks again.

Thanks Thanks Thanks
