Is CalChem compatible with competitors inhibitors?
Most brands update their formulations from time to time and it is not always possible to know what effect mixing inhibitors will have. The cocktail of chemicals produced by mixing products could be detrimental to a heating system and we recommend flushing or topping up with the same inhibitor previuosly used in the system. As a cautionary note if a manufacturer tells you that their product is compatible with other products they could be misleading you.
