I installed a magnaclean on my system today, system is one year old vaillant ecotec 831 with 7 brand new rads. The old heating flow and retrn pipes were used.
The system was also power flushed upon commissioning

After installing I ran the system for an hour and got a loads of black crap on the magnet (can't believe how much black crap came out on a powerflushed system

I know the magnaclean has a chemical dosing point, but can I just isolate the magnaclean and take off the top and pour the chemical in and replace the top?

I mainly want to fill via the big cup as the cartridge tubes of chemical are a lot more money that the standard bottles.
