Smaller tanks come fitted with a 400mm Non-Vented Lid and a 1" or 2" BSP fitting located at the bottom of the tank.

Our larger tanks (10,000L and above) come with tie down points to facilitate handling and positioning with a 600mm Screw Down Lid to ensure ease of access. The tank comes with a standard 2" plastic threaded male outlet which is supplied loose but can accept up to 6" flanged outlets. A 2" Isolation Valve is also supplied to ensure a simple connection.

At Safe Fence, we supply a range of connections and fittings suitable for agricultural, commercial and domestic applications:

  • Outlets – located on the lower half of your Water Tank where you can access the water.
  • Bylaw Kit – components designed to protect the water in a tank from contamination.
  • Float Valve & Float – these control the filling of a tank so that it can be flushed.
  • Insulation Kit – used to provide frost protection during periods of extremely cold weather.

Installation Guidelines:

All Potable Water Tanks must be installed in accodance with The Water Supply Regulations 1999 in order to be properly used for the storage of drinking water.

All tanks have been designed to be manoeuvred when empty and under no circumstances should they be lifted when containing water.

Be careful to avoid damage that can be caused by the tines on forklifts and it is recommended that you use a crane to lift large tanks from the lorry.

Tanks should be unloaded onto a smooth surface that is free from sharp objects which could cause damage. Tanks must not be sitting tight against a wall or a similar structure and must be installed on a firm, smooth base of reinforced concrete.

We recommend a tank base depth of:

  • 150mm (6”) for tanks up to 10,000 Litres
  • 200mm (8”) for tanks over 10,000 Litres

If a large water tank is inadequately supported, the tank can be weakened leading to eventual failure and liquid leaking. The location of the installation should allow enough room to carry out all maintenance activities. Precautions should be taken against accidental contact with the tank as impact with the tank – especially at low temperatures – may result in tank failure.

Make sure any fittings are hand tightened – if they are over-tightened, they may leak. It is important that fittings, valves, pipes and other accessories are fully supported. Fittings and tank attachments should not carry any weight. Be sure to test the installation by filling the tank with water before putting it into use.

As Water Storage Tanks are inspected annually, you must properly and regularly maintain your tank to prevent bacteria from growing inside of the system.
