Answer 1

i take it you're talking about the following one here

see the little know, up where the tube is on the top?

that's the adjuster for the water flow

which you can increase or decrease by simply turning it left or right

for the little piece you don't know where to attach, check your instructions again, they usually have pics in there and also show you exactly where everything goes
