I'm keen to avoid having to change the existing pipework, and hoping to just attach onto the existing 15mm isolator. In a perfect world I need a 15mm female to 3/8" male reducer, but happy to combine bits as needed.

Bought what I thought may work before removing old tap, but is a male to male reducer with a compression fitting on the 15mm end requiring extra copper pipe and another compression fitting.

Have tried eBay, Amazon and Screwfix but coming up shortly. Anyone experienced with installing Grohe taps in UK as a replacement?
