I can hear a 'click' and the water runs slow. It is a high tap for the kitchen. No idea what brand but thinking Delta. The other water faucets in the house are fine. I cleaned the screens but think there must be some kind of mixing valve. I took the cartridges out and rinsed them. They appear to be in good shape but are 15 years old. I really can't buy new ones because of being unsure of the brand and water off sill sends some water through the stems into the sink.

So the question: Is there a mixing valve that moves and may be clogged?

Someone already mentioned the screen but have you removed the aerator on the end of the faucet. They do get clogged with crud and the screen needs to be cleaned every so often. ^_^

Some faucet heads are not made to come apart as easily as the heads of old.

My Delta has a flow and spray head built into one. The 2" wide rubber
"plate" where the water comes out is recessed into the stainless body of
the head. It is not made to simply unscrew like the old style aerators.

I did manage to get mine apart but the only thing to grab onto is the
little nubs for the spray function, so there is going to be some
cosmetic damage. Actually, you couldn't *grab* anything. What I did was use
a pair of channel-locks and *pushed* on the side of 2 nubs until the plate
started to turn.

Once it was apart, there wasn't much to clean or back flush due to the
dual functionality design of the head. Trust me, I tried, but to no avail.

I've found government mandated flow restrictors in some aerators that were clogged with debris too. Of course I remove those damn things anyway so some useful amount of water will actually come out of the faucet. There are soft jaw pliers which are useful for disassembling smooth surfaced items that are screwed into something. Sometimes a strap wrench will work if you can get one on the item. Harbor Freight has a cheap set and of course you can also buy an expensive set if you wish. ^__^

Soft jaw pliers or a strap wrench will not help with the disassembly of
this type of faucet head because there is nothing to grab onto:

Like I said, the only way to unscrew the portion of the faucet where the
water comes out is to use those little tiny nubs you see and hope you
can break the threads without damaging the nubs. You have to push on the
sides of the nubs while pushing down. They are not really made to be taken
apart.

That's why you can't buy internal parts for those heads. The vendor just
sends you a whole new head, typically under the lifetime warranty.
