Is there any way to use a small wire brush to remove the scale?

Have you Emailed Hass to ask for their recommendation? They're usually very helpful info@hassmfg.com
Maybe kettle descaler sachets would be better (it may be a stronger acid, unless you have glacial acetic?).

My acetic acid is 60%. I'll try this afternoon / evening and leave to soak overnight.
Good luck!
I read on the Hass site, valves are SS 301 with teflon seals and guides
Could a valve stem be bent? Perhaps from teflon tape upstream, or other debris induced after the filters?
I use HASS filters but did make a mistake using black iron fittings after the filters, all SS fittings are very expensive
I notice a bit of rust in my HASS water output when sitting for even a couple days
I can see it as brownish water in a 6" flow in clear tubing right after turning on the flow. Gotta be rust...
a bit of rust could inbed in teflon or bend a valve...

Well this is odd, I've just done a darkroom session and had no issues with the sticking valves; I'll monitor the situation.
Instead of acetic acid try some phosphoric acid. It can be had at Home Depot and is sold as an etcher for concrete. Boaters (I live on a 44-foot boat) use it to descale hoses and plumbing of sea critters. Think barancles and shellfish. Phosphoric acid dissolves them completely and does no harm to the plumbing.
Some day we will back back living in a dirt house. All of my darkroom equiment is in storage waiting for that day.
