Could you confirm to me the legislative requirement to carry out tank draining and internal/external inspection of the fire sprinkler tank – I believe this may be 10/15 years but do not have access to BSEN12845 to look over the specification/recommendations laid out in the standard.

Thanks in advance

To the best of my knowledge, all storage/pressure tanks shall be checked for externally for corrosion ever 3 years and drained, cleaned as necessary and examined internally for corrosion. Also shall be repainted and/or have the corrosion protection refurbished, as necessary.

At 10 year intervals, all storage tanks shall be cleaned and examined internally and the fabric attended to as necessary.

You should check out the BS yourself the local reference library may be able to help.
