I'm trying to install a Grohe Minta-Touch single handle faucet. My home H2O lines uses the standard 3/8" faucet connectors. In looking at the Grohe connectors, it appears to be 'mm' or metric sizing. So a bit surprising since I'd thought Grohe's faucet would have 3/8" connectors as well. I'd check other Grohe faucets, and they include 3/8" female compression fittings. And my Grohe 31359DC0 is brand new. Thus, I'm looking for guidance on how to make the actual connection fit correctly?
I'd try using a 3/8-1/2 converter, and even with thread-sealer, o-ring, I'm getting a slight leak in both hot-water, cold-water. So looking to see if anyone ran into this problem with this particular Grohe faucet? Any help would be welcome...
