I think the tool is used from the side via the lower side covers. It is a "T" handled tool, with a slot cut in the other end to engage the tap (cock) levers. There is a picture on the carrier tools thread>
I have some drain tubes. They are separate and are a small funnel,(at a guess 40mm dia.) the spout of which, is a bit of copper tube. There is no "Y" that I am aware of. I believe they drain separately from the hull.
