Don't knock it until you've tried it. It's more than enough to wash your veggies. And it really isn't appreciably longer to wait on the pasta pot to fill. A couple of seconds.

I have a grohe faucet and would also like to know if there's an answer to your question!

I LOVE my faucet and have gotten used to the flow rate. I like that when I turn it on the water doesn't splash everywhere. BUT my husband hates it. He is not used to it at all and would like to up the flow rate a bit.

Hi Chitown-
I know my dad had a plumber up the flow rate in his girlfriends grohe. I talked to him tonight and he said that there is something in the faucet that you replace and then the gpm is the standard 2.2 gpm.

I think the slower flow may drive me nuts. If I want to use the spray to power wash I dirty plate, I think I would be annoyed that hey went out of their way to make the faucet less effective.Especially grohe's aren't cheap and now to pay a plumber to "fix" it right away. I wish I didn't like the way it looks so much.

Found this online. Instructions for removing the limiter.http://www.ehow.com/how_12118927_remove-water-flow-limiter-grohe-kitchen-faucet.html

I just changed the flow restrictor that came with Grohe faucet. The new faucet came with the gold coloured restrictor [I think 1.7 or 1.8gpm?] I replaced it with the red one from Grohe which is 2.2gpm. Took 5min to do, all better now.
