Mr. Eamonn Smyth:

I disagree with the Deputy. There is an onus on a person who does a job to do it right. The workmen have all been trained in most cases. The issue is not new and there has been a lot of training schemes down the years.

We know how to plumb a house with an expansion vessel on it. That has been there since I was a young lad and that is a while back. That is not the issue. Shortcuts are being taken. They may be taken in absolute innocence in that they do not know that this creates a different risk and they ask why they need that when they have the other there but the reality is that it is a workmanship issue.
