Storage Cisterns used to today are made of plastic and if you are going to install one it is essential to ensure that the bases completely supported, otherwise the way to want to contend will cause the plastic to stretch and eventually break at the unsupported point. Old galvanised ones did not require this total support. These old metal cisterns are invariably left in the roof space and removing them requires extensive additional work. Feltham Plumbers will remove and replace this item. Sometimes, old asbestos ones are encountered. These are fine while in use, but when their past their useful lifespan is essential that they are disposed of safely. Do not cut the material, as this will make a dust which is extremely dangerous to inhale, even a minute particle can be hazardous to your health.

The size of a new cistern should be a minimum capacity of 100Ltrs if it is to serve only either a system of cold or a system of hot water, however, this volume should be at least 200Ltrs ideally 250Ltrs if it is to serve both cold and hot supplies. In order to provide the best pressure possible at the outlet points, such as showers and taps, the cistern should be located as high as possible, which may require the construction of a supporting frame. If you make a stand it is essential that you use sufficiently strong timbers and breasts to ensure that it can take the weight of the cistern when full of water. The weight of water is quite substantial for example 1 Ltr of water weighs 1kg, therefore, 250L of water would weigh 250kg which is equal to a quarter of at ton. A Feltham Plumber is aware of this.One point to note is that it is essential that no jointing pastes compounds are used to make the connections to the unit as these will have a detrimental effect on the plastic walls of the unit, causing it to break down and reducing the expected lifespan quite drastically. The connections are made with what are referred to as tank connectors. These are simply passed through a hole made in the unit, with a plastic washer included, and when the fitting that is tightened it clamped tightly to the system wall.
