Try a piece of rigging in the drill open the end a bit it will chew out anything.

Nice job Kevin.
I’m thinking of replacing mine soon, not because of corrosion but there seems to be a blockage in it. I presumed it was calcium and tried acid but to no avail. Next step would be to drill into it but would the original fitting have had an inverse U-bend inside the tank to prevent back pressure on the feed pipe when the tank is full?
I’m not sure if I read that somewhere or just made it up in my head but it would make sense and I wouldn’t want to destroy it with the drill if there is.
Anyone know anything about this?
