Kitchen faucet issue - Hansgrohe Metris Select

7. Have you checked the supply lines for gunk?

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.
