    Had a call out earlier, leak through ceiling from boiler. There was a calmag magnetic filter which had blown completely off the threads which you unscrew to access the magnet. Baffling because id have expected it to be split/damaged.. Screwed it back on,topped pressure ran heating upto temperature and everything seems fine..

    Has anyone had similar problem with magnetic filters?

    Probably wasn't on correct if there was no sign of damage. Never used one myself always used Magna.

    Hi Just had the same problem at the weekend, had a new combi boiler and a cal mag filter fitted Dec 15th 2016 worked fine until last weekend when a loud bang was heard upstairs and then water ran up to find the lower part of the filter had blown off with water leaking into the bedroom and through the kitchen ceiling
    Plumber who fitted it came out and also could not find anything wrong with the threads but said he would get in touch with supplier, phoned today said a new filter would arrive tomorrow though the bowl that has blown off have now been replaced and made off brass.
    No fault by the plumber and no I did not mess around with the filter but wonder if this has been changed due to a number of filters blowing off
    Not sure where to claim for damage Cal Mag or own insurance

    You claim is with your plumber if he/ she supplied it. They will have to chase the manufacturer

    YEP. had two of them BLOW-OFF due toe bad threads on fitting about 4 years ago, stopped using them on systems. I do't know if its a bad design OR manufacture fault, but they cant take the pressure and high temperature, i think they expand a little. Been using spirotech and magna clean since. I kept the calmags and use them on my flushing machine, low pressure, so ok.

    I see loads of magnas leaking from valves, more so the old red valves, the other day I changed leaking valves on a newer one, been fitting the Fernox TF1 Omegas lately, 25 year warranty cant really go wrong.

    Spoke to calmag and they are sending me a replacement newer model. I asked if they have had alot of faults and he swiftly said not really any at all. I smell bull... Cheaper is not always better
