There really should be an Agrement certificate for such a system. This certificate will demonstrate that the system is designed and manufactured to certain standards and most importantly is suitable for use in this country, where our climactic conditions, soil types, water usage etc are far different than our other european neighbours. Homebond will not allow the use of building materials in registered dwellings unless they have Agrement certification. I wouldn't spend a considerable sum of money on something as fundamental as a treatment system unless it was certified. check out the Irish Agrement Board website for more info.........
