Hi, I want to top up my central heating system with more fernox, I've had a leak over time and have topped up the system with water periodically so I'm not sure how diluted the system is, my question is can you add to much fernox, should I just add say half a bottle or will it not really make much difference. It's a pressurised multi point system. Thanks for any advise.

You can overdose with inhibitor, but not with a single bottle on an average system so I would also say just stick the full bottle in.
