Reflecting Fountain

I tested a Back flow Preventer this afternoon with Nick from the Council. We did the first test and it failed so thinking we had done the test wrong Nick had a go then I had another go,rechecked our procedures and they were correct and it still failed. We pulled it to bits and got it working again and then the down stream valve failed so tomorrow we are going to pull the valve out and check it and all this was while the plumber was watching as he has not done many tests himself. Another good turn out with the Run Timaru group for coaching tonight. I captured this reflecting after my coaching session tonight.
