Jockey (excess pressure) pumps are used a lot up here north of the 49th parallel. I was easily picked out in a crowd many years ago as a Canadian as I mentioned the use of them for sprinkler trim. They work OK IF you have clean water. They are a curse when using lake water as the fine sediment from the water clogs the pressure switches and other components. Retard chambers are allowed in Canada, it just seems the use of excess pressure pumps is the flavour up here.
