In this way, overdosing in the event of a small leak, even after a few days of absence, is prevented. The advantage is that it is very cheap.

+1…. Been using drip line top off on multiple tanks for over 30 years… without fail or problems.
ATO fills a 10g holding tank and drip lines using plastic adjustable air line valves replace evaporated water.
