What's all this about British taps?

[mtfasuncion]

Have found a zombie thread pigletjohn comment about taps that has me worried. He says imported taps aren't suitable for low UK water pressure. Ordinary UK taps have 15mm tails on basin and will be WRAS approved. What does this mean? Can I not use Grohe basin mixer taps? Any experiences to help, good or bad? Anyone bought (cheapish) Grohe taps online and is happy with them?

Have you got a hot-water cylinder? What colour?

I am not sure. How do I find out? I have a combi boiler, but no tanks in the loft or in cupboards.

then you should be fine with european brands like grohe/hansgrohe

The wras approval is a certificate that all the materials in the tap are safe for use with drinking water.

Thanks, everyone. Very helpful
