Grohe Concetto installation tips
on December 29, 2010
The Grohe Concetto pull-out kitchen faucet is very nice to use once installed. The flow of water is very silky because of the smooth controls. However, for you DIYers, there are some tricks to installation. It was installed by my handyman, and when things didn't go well, we consulted Grohe support and a licensed plumber. After that, my handyman was able to complete a successful installation.
The problem with this faucet is that it uses a very long spring (PN 07 240 in the manual) rather than a dead weight to retract the faucet hose. If anything binds or rubs against the hose, the spring cannot retract. The binding occurred at the horseshoe shaped piece that is 2 pieces below the triangular Part A. We positioned the horseshoe piece very carefully. On Grohe's recommendation, we also did not use Part E, a white plastic collar of 2 side-by-side circles.
The plumber told me that these things are very hard to get right. The installation manual has no written instructions, and is just pictures.
Also note that you should measure the distance between the faucet holes in your sink. I did not and discovered that the handle projects out so far that it was hitting my embedded soap dispenser. So I had to position the lever on the left side of the faucet, not on the right side as shown in the product picture.
While I really like this faucet, I miss some features from my old pull-out faucet (which broke). The old faucet used a weight system, and I think that is superior because it retracts more smoothly and faster. Secondly, the Grohe has a button to actuate a high powered spray. But you have to turn off the faucet in order to stop the spray. The button cannot turn the spray off and on like my old pull-out did. On the plus side, the Grohe can be clicked into place when retracted. My old faucet used to hang out, and you couldn't really get it to retract 100%.
