I did a hard piped drain on my system to avoid needing to use these

having to tit about with bits of hosepipe.


Yeah thats the kind of thing that was on the system in my old house in
Dennmark, two ballofix valves undeneath the boiler marked "dump" and
"fill", the fill one had a an extra ballofix sticking out on a tee to
squeeze in chemicals like inhibitors and such, the rads had auto vents.
when I swap my boiler that is what I want to have made.
