VIDEO - How to add inhibitor to your pressurised central heating system

This is the most complicated way of adding inhibitor to your system, but it is an important method to know if you have a pressurised central heating system. James the plumber takes you step by step through this process with his usual charm and panache!

As he mentions in the video, this is a complex method, so we advise you watch the video carefully and only attempt putting it into action if you have a good working knowledge of your heating system and are used to carrying out more difficult DIY jobs around the house.
