A leat runs to the east of the town's main street but it is uncertain when it was first constructed. By the early seventeenth century, the southern end of the leat and one mill are shown on a map. There were three main mills: Higher Mill, Lower Mill and Middle Mill. Higher Mill appears to have always been a corn mill and it continued to produce animal feed until 1974. It has since been converted to housing but a water turbine remains. Middle Mill was used as a woollen mill in the nineteenth century and was also associated with Bilbie's bell foundry (see below). Around 1900, the mill was steam powered and had a boiler delivered. It is labelled as an axle works on the 1904 Second Edition Ordnance Survey map. The only remains of Middle Mill are some walls and a chimney base. Lower Mill ceased working in 1968. The building is now in residential use but the sluices (made by Stenner and Gunn of the Lowman Ironworks, Tiverton) can still be seen, as can the water wheel and gearing.
