Sorry - I can't offer any help.
But I know what HARD water is - I grew up on a poor well
in a limestone bed.

1. dripping taps / minor leaks will cause faster
build-up . seems obvious ..

2. Worry about the water heater - we could hardly
_ move__ the lime-filled old water heater
from Mom's house .. solid clogged !

You need something like CLR but the problem is how to get it into the
pipes to soak. It is probably easier to replace them and put in a
softener for the whole house.

If it is all PVC, drain the system, cap the pipe at each fixture, fill
it with muriatic acid from the highest point, take a nap and flush it
out tomorrow from the lowest point. It will be clean as a whistle.
Just be aware this will bubble up a might so be careful.

It's phosphoric acid with some added surfactants. If you don't live in
farm country, phosphoric acid is in the masonry section of Home Depot etc.

It all being PVC is key there. What about valve stems in sinks, toilet
components, etc? And getting it in, making sure it gets
where it needs to go could be an issue too. I'd dilute it to about 10%
or so too. Personally, I'd be OK with using it, but if he wants something
that's food grade, he could use vinegar or citric acid.
