Kitchen faucet noise
 

Strange thing - My kitchen sink has a two year old Glacier Bay faucet with
spray attachment. Recently it has been making a 'thumping' noise at low flow
rates - about 3 times per second. I can feel it in the sprayer hose, but not
the metal plumbing. As I increase the flow rate, the frequency of the thumps
increases, until at max rate it stops completely. It really has me baffled,
as there has never been an air hammer 'tube' there in the 14 years I've
lived here, so I don't think that would be the cause of the problem.
Comments will be appreciated!
TIA

Right, it's not air hammer or water hammer.
It's related to the spray wand.
Inside the faucet base is a "diverter valve".
Yours probably has one with a rubber diaphragm design
(I'm guessing) and these will make odd thumping noises
when needing replacement.

Did it come with any warranty?
