Help - what causes copper to corrode?
Just had a leak in my heating system. Cut out the offending pipe and spliced in a new bit. Looking at the old is full of green (i assume copper)
corrosion.
What causes this? The pipe is the feed to the boiler header tank.

in summary the builders messed up when they built the house.
Hmmm, who'd buy a house from a building company "Wilcon"? well the previous owner is who!
well its fixed now, just got to dry the house out.

I had a series of problems with my central heating last winter.
Radiators full of sludge, cold patches in the rads, and pin hole leaks all over!
Turns out, having followed advice from plumbers on here, that my pump was running too fast, so the water was going up into the header tank and
circulating through there. This aerated the water in the c/h system leading to the corrosion.
Drained the system, took all the rads off, ran gallons of water through them all, took the header tank out, cleaned it out, put the rads back on,
refilled the system, added corrosion inhibitor and then turned the c/h pump down from 3 to 1!
So far this year no problems at all.

its strange really, how bad copper is for the job. It radiates heat fast, corrodes at the drop of a hat, conducts electricity (bad for safety), and
its expensive. Whereas plastic pipe is non of the above but is regarded as a bodge by many. Perception will change with time i suppose. I cant stand
plastic myself, just cos it looks messy compared to well done copper
