Fernox TF1

[Wylie]

Since I have a problem with my boiler I decided to drain my TF1 to see if there was a lot of buildup inside, water that came was just a little discoloured but when I slid the magnet out I noticed that the magnet itself is corroding. Just wondered if somebody can tell me if this is normal?

no it's not normal. How bad is the corrosion?

Thanks for your reply, it covers around 10% of the magnet and has taken off the top coating in these places. What would be causing this?

Lack of inhibitor in the system

That's what I first thought but I didn't think the magnet actually comes in contact with the system water?

Youre right. It doesn't. Maybe some waters got into the pocket that holds the magnet. I wouldn't worry about it too much. It sounds like the corrosion is just cosmetic. You could give the magnet a spray of wd40 to prevent any further corrosion.

Yes - Mine is the same.

It's a design fault imho. The bleed valve point straight towards the hole that the magnet fits into on the TF1, and you can't change the angle of the bleed valve as it is on a screw thread.

As soon as you bleed it a few drops of water goes into the hole and there is stays.

I managed to dry mine out with a bit of kitchen paper stuck on the end of a kebab skewer - but please sort it out Fernox. Great filters apart from that.
