Our service engineering team attended site to carry out the work. Additionally, an engineer from Neil Lowes Drainage, who provided a tanker for the vacuuming and jetting of the tank, attended.
Our engineers, Alan and Sam Werrell, cleaned the tanks completely, removed the pumps to clean and service them, then re-installed them. They also fixed the problem with the NonReturn Valve which was caused by a stone obstructing the flap.
The entire system was vacuumed and jet cleaned, Tank lids were replaced and correctly sealed and then everything, including all of the control systems, was put through a thorough test programme.
