screw on, w/ the embedded filter within). And you cleaned it.

On 2 of my faucets, when the water flows slows down significantly, I have to clean the filter out pretty frequently (located at the tip of the faucets, within the screwed on portion of the faucets), and I have just left the filter and/or tip off, and let the faucets run w/o out the filter (when I turn it on). The water pressure is fine then.

cleaning it usually works, but they are pretty standard in size and trivial (1 or 2 $) in cost.

Water flow is controlled by a valve cartridge. If something is loose inside, that would slow the flow. There's a set screw that holds the handle on. If that screw is loose, the handle would not open the valve all the way either.

had no idea one could cram so many parts into a freaking faucet!

Not only is the flow rate low, but when I turn it on, the water stream invariably splashes in the sink and then lands on the wall behind it.

Check the shut off valve too. Get a bucket and flush the supply line into a bucket.


Though it’s most likely the cartridge. I would start with:

Pull the cartridge and look for gunk. Rinse it in another sink.

I didn’t see any videos on that model but the procedure should be similar to this video.

1. Shut water off under sink

2. Remove set screw from handle. Often hidden under a rubber plug out of sight

3. Remove trim ring, if any, to expose “bonnet nut” that holds the cartridge under pressure.

4. Remove the bonnet nut and pull the cartridge.

5. Rinse the cartridge. There is probably visible calcium in the little screens. Worst case you can soak in vinegar.

Don’t lose the little o rings if the pop loose. Plug the sink when rinsing.

I got an email from them asking for the original 'facture' (invoice), and they will send a new unit.

Now I just have to get a plumber in.

Yeah, all those mid to higher end fixtures are usually covered by a lifetime warranty.

I’ve been surprised how easy it is to get new parts.

I had a Kohler valve stem frozen. I was about to purchase a new one for like 80 bucks and a plumber buddy told me to call Kohler and they will send you a new one.

Now that’s not to say they won’t take your money if you go online to their parts page. You have to know to ask.


Sure enough, they sent me BOTH no questions asked. Didn’t even ask for a receipt.

Danze sent me a whole new pot-filler when it started leaking from the body. No receipt. Just mailed me a new $400 dollar pot-filler.


You should pull the old one apart just to see how easy it is. There’s no guarantee the new one won’t clog. We used to get clogs every time the water in the building would get shut off for someone in the building doing work. Sediment would get kicked up.

And probably use it for spares.

Our water here has a lot of 'calcaire' so the electric kettle has to be descaled frequently, the glass wall of the shower has to be squeegeed daily, and you have to use specific laundry soap.

Our apartment building was constructed in the 1960s, early 70s, so the pipes are aging.
