We were somewhere around Barstow, on the edge of the desert, when the

something like:

[1] and no, there wasn't a water softener in the system, or any evidence
of a bag-in-the-tank type scale inhibitor in the tank.

But you never know - there could have been, for years.

There's no evidence of there ever having been a water softener, and I
started working on this place when the new owners moved in 2-3 years ago
and I'm pretty sure they hadn't touched the tanks, so hadn't removed any
bag-in-tank inhibitor themselves. Maybe the previous owners took it with
them ;-)

Incidentally one of the jobs I had to do for the current owners a year or
2 back was deal with a blockage in the feed pipe into the CH system. IIRC
the pipe - about 2-3m of it - from the header tank down to where it joined
the system was pretty solidly blocked and I replaced it with a length of
plastic. Normally one gets a fairly localised plug of scale where the cold
feed hits the hot water in the system but in this case the blockage
extended some way back up the pipe. Maybe the brown sludge that I found in
the HW cylinder had occurred in the feed pipe and solidified over some
length of pipework.
