Black Bottom . . .

But not a “new rhythm” . . .
 
When you open a can of baked beans from a reputable manufacturer you don’t expect to see the tinning is missing from the inside bottom half of the can, especially when the can was well in date.  The company has received three photos and a snotagram (well a clear technical report to be honest).  Another can from the same batch was exactly the same.
 
The elusive drip part four is delayed because some burk (drip) neglected to seal the top of the thread (silicon sealant) so not only did water make its way out through there, it sat in its own little reservoir between the flush pipe and the outlet.  So I’ve had to wait most of the day for this to dry out before sealing, and now I’m waiting for the silicon to set before flushing again . . .
