Are Flexi Tails With 8mm Bore OK For Kitchen Mixer?

[seniorservice]

I'm putting a new monobloc mixer in my kitchen. As access to the underside of the tap is almost impossible, I thought I would use flexi tails.

The only flexis available for the M12 threads on the mixer have 8mm bores. Is this enough to feed a kitchen tap, or will they restrict the flow a lot?

Are there M12 flexis available with bigger bores?

welcome to the world of being a plumber where you have to be a contortionist to do many jobs!
What type of hot water system do you have?

Combi hot, main pressure for cold.

Thanks

It will be fine in that case. You don't need 15mm supply to the hot water tap either. Run it in 10mm microbore from close to the combi. You'll then only draw a cupfull of cold before you get piping hot water.
