Reed & Karen,
In the past, and I assume in the present, there have been some owners that find the water connections on the street side of the Oliver to be hard to get to. Primarily I think this is because they have had some problems with knees, back or related physical issues. By putting a quick connect on these connections once and leaving them there, they have found it easier to simply push on the quick connect versus screwing and un-screwing each time.
