This faucet was installed two days ago by a professional plumber.  After he left I have been using it and am very disappointed with the water flow rate.  I live in CA and apparently they have placed limits on this
important function but I doubt very much that they would limit the flow rate to this degree.  It is little more than a trickle and is unacceptable.  Now I'm forced to see what can be done to rectify the situation.  Also, the aerator is recessed in the spout and the odd little plastic "wrench" to remove it has
failed to work for me.  I wish they had put the aerator as an appendage so as to be removable in the customary way.  Bad design here.
