I think I'm tending to agree re replacement. The calcium coming out (using brick cleaner) is like 10p size lumps; maybe 3-4mm thick. It's like tree rings; sandy, dark, sandy; so that's UK, Spain, UK; and there's more to come out!
My recommended option, bearing in mind the huge usage your heads are getting, would be to rip out the pipe and replace it rather than muck about with chemicals etc.,,,,,,, The effort of taking the pipe out is worth it to do a proper job, compared to trying to clear it in situ.
I'll fit new rather than mess about with it; problem with getting it out is that because of the build process (charter spec) the loop is much higher than standard and looks very difficult to get at and remove (could be mini hack-saw job)!
Second option would be to take out the pipe, shift as much **** out as possible by banging and poking, bung up one end then fill it with brick cleaner for a while.
I've done it once before, fitted new; not Seraph - Moondance
Anyway now time to try more Hcl and maybe then a visit to Force 4.
