..has got a drip to it.. how bad is that? I put a bucket under it to try to gauge how much its dripping a day, but it has been doing it a while from what it looks like.. Is it worth it to just swap the valve if Im planning on swapping the tank out this summer anyway? Imminent danger? I would assume itd be a matter of dropping power to the tank, shutting water off, draining, etc. .?
