pumping over

Pumping stations, also called a pumphouse in situations such as drilled wells and drinking water, are facilities including pumps and equipment for pumping fluids from one place to another. They are used for a variety of infrastructure systems, such as the supply of water to canals, the drainage of low-lying land, and the removal of sewage to processing sites. A pumping station is, by definition, an integral part of a pumped-storage hydroelectricity installation.

    Hi, I have a stove pumping over into the f&e. The pump and thermostat both work and the system is free from sludge (very clear for an open vented system). The layout seems a bit funny to me but the customer reckons its worked for years. (I did spot two vents into the F&E so maybe someone was...
