Hi all,
I'm in the US, and have a Grohe kitchen sink with a pull-down sprayer. I think it's from the "Concetto" line; not sure, but it's relatively new construction (2014). I need to connect the pull-down hose to a standard USA portable dishwasher from Whirlpool, so I need to find adapters.
I'm having trouble finding the right ones to convert from the hose to normal aerator thread sizes. I removed the metal piece containing the aerator from the end of the hose; I can't manage to remove the aerator itself from the metal piece; not sure if it comes out or not.
Anyway, it looks like I need a male 55/64" connector to attach to the hose, BUT the thread pitch is large; I think it's 14 TPI (I measured 14.5 but I could be off; 14 TPI sounds more standard, maybe it's a common metric size).
Any ideas how to convert to this weird large thread pitch from standard aerator dimensions? I have the adaptor that came with the dishwasher, which has a typical 15/16 and 55/64 sides (can't remember which is male/female). The problem is the 14 TPI part.
Thanks for any advice!
P.S. Does Grohe manufacture for non-US markets or something? Anyone know what's up with the weird thread size on the hose, or it this typical in pull-down hoses?
