Removing built-up sludge and magnetite from your central heating system can sometimes be a real chore. Alleviate the worry with a bottle of X400 Sentinel Sludge Remover. It will help restore circulation to pipework and radiators to prepare the system for installation of new parts.

It should be circulated at normal temperature with all valves open for a minimum of two hours or until a satisfactory performance is returned.
