The button below links to a video showing Peter and Paul starting the C F Wilson single cylinder diesel engine. This drives the triple-throw plunger pumps  made by Powell's of Brancaster. 

The boreholes and pumping station at Massington provided most of Ledbury's water supplies in the early 20th century. A single-cylinder oil engine made by C.F. Wilson & Co. of Aberdeen around 1920 powered pumps via an overhead line shaft. The triple-throw plunger pumps were made by Powell's of Brancaster, Norfolk around 1910. The engine is started using compressed air. A wrench levers open the exhaust valve, allowing the engine to be turned to just over top dead centre. After the exhaust valve is closed the compressed air is turned on and some extra fuel is admitted to the cylinder. A lever is used to admit short bursts of compressed air into the cylinder and turn the engine over until it is running. A pulley and belt from the main flywheel drives an overhead line shaft, transferring power to another belt down to the pumps.
