Originally installed at Alton Court Waterworks Pumping Station, Ross on Wye. It was in general service until 1964 and was last used in 1970. For some years from 1932 onwards it provided back-up to its successor engine, an Allen two-cylinder diesel engine which can also be found at the Museum.

1880: Originally installed and housed in a cellar, it pumped water for household and garden needs from a deep well at Taplow Lodge on the Cliveden Estate, Buckinghamshire. Discovered by the National Trust in 1991, it was restored by local enthusiasts and began to run again in 1995 and until 2004, it is believed that the engine was run only once a year.

The EPV5 type is a vertical 5 cylinder diesel engine. It was housed at the Royal Ordnance Munitions Factory in a windowless bunker, guarded by a Lewis gun post, and close by was a purpose built reservoir to pump water for the site in case of fire.
