I just had my Magnaclean fitted by a plumber and you can hear the water trickling through it when the heating comes on? ... that can't be normal can it? .. mine is in my garage, but if this was in my house it would be very annoying.
Although since he drained it and refilled it, I can also hear water coming through the pipes in the house too, just not nearly as loud. I guess that is because there is too much air in the system? I'll trying bleeding the radiators tonight and check the pressure.
Sounds like air in the system. Bleed each radiator, and don't forget the bleed valve on top of the Magnaclean itself. Sometimes if water has been severely agitated it can contain a lot of tiny bubbles that will have got in to the system during the refill, and it might take several cycles of bleeding all the rads and the Magnaclean to remove them. If you let air out you may need to add more water if you have a pressurised system.
