Hi! I want to clarify at the outset that the tiny leak I refer to in the title is not in a normal pipe carrying water under pressure. Instead, it's in the set of pipes of my hot-water heating system, and my particular system is an old-fashioned one that doesn't have a pump (it's a gravity system) so that the only leak-promoting force is gravity.
The leak is in a pipe right near the boiler, and is easily accessible. As the water has dripped out over the summer I haven't refilled the system of course, so as the weight of the water above the leak has decreased, the leak has become very slow-- one drop every several minutes.
So I have two questions: 1) What kind of sealant should I use? 2) Is there a sealant I can employ without fully draining the system first, which is a procedure I'd like to avoid?
