Hot water temp seems ok but flow has got slower.
Does not appear to be a problem with the diverter valve, as it is not bypassing. (this valve was changed last year)
Mains cold pressure is fine.
The last sentence in the description of the problem, says it all.
I too, have had the problem, Tony. But, in addition, to the hard water,I discovered something that I didn't know. In our home's water system (our home is 30 years old) , someone prior to our ownership had installed a 6' section of galvanized pipe (possibly a repair). If you're not familiar with galvanized pipe and what hard water (High iron content) will do, it rust from the inside out. This 6" piece was almost totally clogged with rust and corrosion. This is also the effect it can have on a water heater. Especially, the sacrificial anode rod inside the heater (if it's an electric water heater) That's why it's so important to drain and flush your water heater, at least once a year.
I mention all of the above, because you very well, may be experiencing the same issue. The way to resolve it requires a little detective work on your part. Check you piping to see if any is galvanized pipe, rather than copper or PVC. Keep in mind, that the sink fixtures, may very well may be galvanized, if your home is 30 or more years old. If you find any, I highly recommend replacing it, before something goes wrong in the middle of the night or while you and your family are away from home. If you hard water is a result of using a well, place a whole house water filter on the main incoming water line. It does not have to be a charcoal filter. And to make your water more palatable, install an automatic water softener. For me, it was all money well spent.
Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.
