To return to the petition, I want to clarify this point because we will be coming back to this at a later date. The petition alludes to the fact that potentially over 100,000 households might be affected by the issue with this particular type of non-return valve. Is it possible that so many houses in Ireland might be affected by a faulty non-return valve or water being contaminated by the lack of that temporary connection being disconnected? Mr. Smyth said that one needs three elements for the water to be contaminated, so could this have happened in the case of over 100,000 systems?
