Lee and June from Hornchurch needed a repair to their Vaillant Ecotec boiler. It was leaking water and showed error E75 (water pressure low).
On inspection, it was discovered that the leak was caused by the diverter valve. The water pressure issue required the expansion vessel to be replaced.
We arrived at 3pm on Friday and finished the repairs by 5pm. The heating was back on, keeping our customer warm and happy.
