Copper sulphate on radiator pipe All aspects of plumbing questions and answers, help, tips and information

[siltshifter]

The pipes to/from the radiator in our downstairs loo have deposits of (presumably) copper sulphate where the pipework goes under the floor. This is not an overnight occurrence, the deposits have built up over a considerable period. They are not significant and I have removed some using nothing more than hot water.

Presumably I have [i]not[/i] done what I was told to do on a notice that said

"Our aim is to keep this loo tidy. Your aim will help"

Do I need to clean the sulphate off? If I do nothing will it eat through the pipes in time? Or.........should I bite the bullet & replace the pipework?

Probably the best thing to do is clean the pipes down and protect them with a couple of coats of gloss paint.

Allowing corrosion is never a good idea, but realistically, it could be a long time before the pipes fail. Personally, I would not replace any unless there was evidence of extreme corrosion or a leak.

Thanks for the advice - I'll aim to follow your suggestion...
