Thanks for the replies guys. Plummet: cleaned under the inflate washer. Was some gunk under there. But that wasn't the problem.Peter_Frank wrote: ↑Sat Jan 20, 2018 7:34 pmDo you HAVE a rubber seal ?
...
All my other kites have the rubber sealing, so just curious IF you have this, or just by accident without knowing have had it without this sealing ?
As it seems to work fine for a while when brand new

Friction with rubber seal kicks in before it becomes air tight.
A bit of spit on both sides of the washer will usually does it, a longer term solution is something like a dab of molycote on both sides of the washer, careful though this will attract sand.

Same situation on the cap that covers the 1-way flow portion through the plug, there should be a rubber washer inside the cap that seals against the top edge of the hole in the plug.
Two causes of a leak at the valve body V-bump - plug washer interface that I have encountered :
1. Sand either on the outer sealing surface of the washer or trapped between the washer and its groove in the plug
2. A dimple or compression of the V-bump from a bigger / hard piece of rock/sand closed up in the valve-plug. It is possible to restore almost all of the compression dimple, at least I've had success all three times thus far that I have encountered this cause of a leak.

You mean, the same symptoms
As Juan and I did not have the rubber sealing, and this was the very reason, although impressive it could work for so long without
But apparently one can also have "worn" or "polluted" sealing rings, like in your case ?
I really love these "Boston Valves" - easy and fast and one can get spare valves everywhere (but havent had the need to, so they might last almost forever ?)
