New Water Storage Cistern (Guide)


The majority of cisterns for water storage are constructed out of very tough yet light plastic material that has superseded the old metal types. Therefore if you need to install one by yourself, you firstly need to make sure that the base of the new cistern is fully supported. The support is important as if not correct, the plastic will stretch and break at any weak point. Battersea Plumbers are trained to replace this appliance.


You could on some occasions come across asbestos types. Do not attempt to cut the asbestos, as it will produce asbestos dust which is extremely dangerous if inhaled, even a microscopic particle is potentially fatal. A new cistern should have a capacity of 100ltrs if it only serves a system of cold or hot water. The volume, however should be increased to 200ltrs or 250ltrs if it supplies both cold and hot supplies.


Position:
To provide the best pressure at the outlets, such as the shower and taps, the cistern should be located at the highest point possible. It may need a support framework made of sufficiently strong timber.

The weight of water is quite substantial for example 1ltr of water weighs 1kg, so, 250ltrs weighs 250kg which is a quarter of 1ton. A Battersea Plumber is aware of this detail.

No jointing pastes or compounds are allowed to make any connections to the cistern as they cause a reaction with the plastic walls on the unit, causing a breakdown and reducing its lifespan drastically. The connections should be made with what are known as tank connectors. These are pushed through a hole in the unit, and a plastic washer is also used (included), and when tightened it clamps firmly to the system wall.

Note: Metal cisterns are usually left in the roof space because removing them requires extensive work.
