Your Cold water storage tank

                                   DOMESTIC COLD WATER STORAGE TANKS

Has your household got a cold water storage tank hidden away in your loft space, do you know what condition its in. Do you know what your tank is made from or if it complies with the current water regulations. And most important of all are you drinking or cleaning your teeth with tank water.
Cold water storage tanks have been in our lofts for over 100 years and made from various materials like galvanised steel, asbestos cement. But modern tanks are mostly made from polyethylene [ plastic ] this makes them light and flexible to go through loft hatches and resistant to algae growth within the tank.If a tank is fitted correctly and complies with all the relevant water regulations, then it should be quite safe to drink from, For domestic households the average size is 250 litres or approximately 55 gallons. The following criteria is required to drink from your cold water storage tank.

1] To be made from approved materials and have the WRAS approved logo on the tank.
2] Has a lid which excludes light and is sealed tight and securely fastened to the tank.
3] Has a bylaw 30 kit fitted, which includes a screened overflow, and screened vent on lid.
4] Has correct insulation jacket fitted around tank and on lid.
5] Has a correct part 2 ball valve fitted.
6] Is not exposed to sunlight and not located next to any heat source, so the cold water can be kept      cool as possible.
7] If two or more tanks are installed and connected together for more water storage then particular attention must be made to where the out-lets on the tanks are positioned, to prevent a particular tank becoming stagnant.
If you have any questions or concerns on your tank then please contact us.
