Sorry for resurrecting the thread. I have recently purchased a Grohe K7 Semi pro Medium kitchen tap from Germany(ebay), and a Hansgrohe PuraVida tap from USA(Amazon). I understand that I will need a converter for the PuraVida(USA), however how about the Grohe K7(Germany)? I noted the thread for Grohe K7(Germany) is slight bigger than the PuraVida(USA). My concern is whether the Grohe from Germany fits naturally to the Singapore/Malaysia 1/2' inch. Although I will be going down to Singapore to purchase the converter for puravida, I cant bring along the Grohe K7 as it is huge. Anyone has experience of buying Grohe tap from Europe mind to provide some information? Thanks!
