For the past year or two, I’ve been seeing a lot of these hard brittle flakes coming out of all the faucets in my house (kitchen sink, bathroom sinks, and shower/tub).
Now that I actually have the time and funds to work on this, I’d like to get this fixed!
The flakes only occur in hot water, and clog the shower head. The water is from a city main line, not a well, and we also do have quite hard water. What can I do to diagnose and/or fix the issue?
Some history of the water heater:
- It's a relatively new Noritz tankless water heater, installed about 2 years ago. It replaced an older Noritz tankless heater, which came with the house.
- There used to be a water softener attached to the water heater, but we disconnected it awhile ago since it was old and we suspected it was the source/cause of the flakes.
Here’s a picture of the flakes, for reference:
