But that is not all that matters. The real world is a more complicated place, as I shall explain in a moment. And that is why a floating exchange rate regime makes sense for Canada. The case typically made for a floating rate for Canada is that it gives us the chance to run an independent monetary policy. That is true.
Over-irrigation of the soil takes out all of the embedded nutrients and makes the soil fallow. In addition, it can lead to erosion and runoff, which can make the ground less stable and less able to hold fruits, vegetables, and plants.
If the valve is glued to the pipe and that joint has the leak, then the valve will still likely need to be replaced. If the valve box is filling because it's sitting at a low point and it's simply because of run-off, then you need to modify your irrigation schedule to now put down so much water all at once. You want to avoid run-off (wasted water). You instead want just enough water so that it will all soak into the ground.
