I have 2 question about this item:
First, there is a screw cap on the top behind the faucet handle that goes over some sort of circular plastic device with a small plastic point in the middle. Does anyone have any idea as to what this is is for?
Second, I installed this about a year ago and now there is a small drip
(about twice a minute) from the spout. Can this be repaired without replacing the entire thing?
Thanks in advance for any assistance anyone can give me.
