Upon lifting the floorboards in my house recently, a hugh amount of th



solder joints on the flow and return CH pipes have turned green an have what appears to be crystalline deposits all over them.



I know copper naturally turns green when expose to the elements, but a these pipes are not leaking when installed, what would be causing thi problem

Not cleaning off the flux. The plumber was lazy or incompetent.

Mr F.

Flux on the joints, inadequately cleaned (or not at all) on installation.

What's lazy or incompetant about that? Does it make any difference to the integrity of the joint?

In time, especially in damp conditions, with some fluxes, it can eat through the pipe, and cause pinhole leaks.

Flux is corrosive, it attacks the pipes.
