As a retired BT engineer I can almost be certain that you are not allowed to touch the line outside your property. If you do, when BT find out (it may take years - but they will one day) they will send you a bill for their normal charges at the time its discovered - this will certainly be more...
I have a Mira Advance Shower with the service light intermittently coming on.
To rectify I turn the power on and off and it then operates OK for a few days.
Is it possible for a DIY man to do his own service ? If so do I need to purchase any parts before starting ?
Any help/suggestions...
