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.

The top cap is a vent. If it's leaking out of the faucet, you can put
a new washer in. By chance did you solder it in without taking the
stem out? If so and if you used enough heat, you could have burned up
the washer.
