comment What prevents the water from flowing in a 13mm garden hose?
The path is full of dangers: several 90 degrees turns with a short radius of curvature, there is already one repair connector because I had to improvise a solution with the lowest possible cost, and there is also a little upward slope toward the end.. Despite this, I collected ~500L of water in a few hours.

comment What prevents the water from flowing in a 13mm garden hose?
The device I bought is more or less like the one on the picture: its output can be connected directly to a 13mm hose, but they sell different models that require a larger hose like the one I mentioned.
