Low Level Cold Water Tanks


Ferham Low Level Tanks are available in a range of capacities from 25 to 100 Gallons (114 to 455 Litres).

These cold water cisterns, also called coffin tanks due to their shape, have been designed with a low profile making them suitable for installing in locations with limited head room, such as lofts.
The header tanks are fully enclosed to protect the water from becoming contaminated by falling debris or pests and rodents falling into the tank.
