Replace Magnetic Scale Inhibitor

[Rathilion]

My magnetic scale inhibitor is coming to the end of its 10 year life and needs replacing. This is attached to the pipework just before the combi boiler. I have a few questions that I'm hoping someone will be able to answer. Should I replace it with another magnetic inhibitor or change it to a electrolytic inhibitor? Or can I leave the old magnetic one in place and add an electronic version to the outside of the pipe. Would leaving the old magnetic inhibitor in place cause problems?

If it is advisable to just replace, which magnetic or electrolytic inhibitor should I go for that will screw into the fittings at either end and sit in place of the old one so that it works out to be the same size.

Thanks

Don't bother; it will still be working as effectively as it ever did. If you have a problem with scale fit a proper water-softener.

If you like, remove it and have a look - I’ve seen the bore reduced to a couple of mm in some cases.
