Your skilled tradesperson will use a specialist power flushing machine and take the following steps:

1. Prepare the area – Lay down protective sheets and a container to collect any escaping water

2. Connect the power flush machine – All systems must be fully drained of water before power flushing begins

3. Flush the system – This will be done multiple times and sometimes in both directions of flow

4. Refill the system – Once the system has been power flushed, the engineer will refill the system with clean water. They may add an inhibitor solution to the system to prevent the future build-up of dirt and debris
