We've had this faucet for a year and the hot water has gradually slowed down not quite to a trickle, but could get there. I checked the braided line and there is a mesh filter that had debris in it. I also back washed it from the cold line thru the faucet. It was ok for a few weeks, now it slowed down again. Kraus sent me a new faucet cartridge but that wasn't the problem because it's only the hot side that is slow. I want to get rid of the that mesh filter seeing that replacement feed lines don't usually have it. I can't find a gasket that is close enough in size. I'm tempted to just drill it out, but worried that the debris will now collect in the faucet. I have yet to inspect the angle stop which might be a few steps down the road. It looks to be in good shape, the place is just 20 years old. Any suggestion on how to approach this?

Check the flow through the angle stop.

the washer in the angle stop may be deteriorating slowly.
shut off the main and take the angle stop apart to check it.

After this exercise of trying the cartridge that they sent me, it slowed down to almost a trickle again after turning the water supply off then on. I am planning to replace the shutoffs with quarter turn valves.

Just for completeness, I found the problem to indeed be the shutoff valve. When I let the line run into a bucket, it was strong but spewed out many black bits. I reconnected and opened slowly and the flow was good!

replace the 'line' the black bits may be the NON stainless steel inner tube disintegrating
