Further to the irrigation break, the irrigation system was nearly drained of water and took nearly 3 hours to re-prime.  As part of the re-priming it is crucial to get as much air out of the system pipes as possible as the air can cause further damage to pipework and cause further breaks.  To do this sprinklers are often activated but in the early stages we just plug in to selected valves and allow the air to be blown out this way.  A few members queried why I had water running like this and I took a video which shows just how much air comes out and the recoil force that it has on the pipes.
