Quick disconnect?

Yes, on everything. I use a Y-connector at the water tap, then into a short flex hose. Quick disconnect, then hose to rv, another quick connect, into another shutoff valve. I have a water filter that is used occasionally, it has quick conects on both sides, allows me to put it between the water tap hose and the hose to the RV if needed. I only use the better quality brass connects, and always carry a spare set in the tools. Most have replaceable o-rings, but I have not had much success with those.
