First and last line of the water template flushes the system to the water and then from the water to generally more accepted solvent - methanol.
### Why water is special?
Water mixes exothermically with other solvents like methanol or acetonitrile. To prove my point this is how it looks when you are going from methanol to water and back:

Flow was set to **0.5 ml/min**, water has started to be pumped at 5th minute. You see that the pressure raises sharply around 6th minute (0.5 ml dead volume) and then it slowly drops in course of approximately 5 minutes (2.5 ml volume before flushing MeOH). The same applies for the change back from water to methanol. The pressures are lower for the normal operating flow of 0.2 ml/min.
