How to Fix a Valve

How to fix this leaky valve?
First, a mild little
Drip…drip…drip
But it’s worn just a bit more
To a moderate
Drip, drip, drip
And on so it goes to bleed out
A smidgen here and there,
Muttering and stuttering
About things it could once contain.
Nothing a spritz of WD can’t fix.
Maybe some plumber’s tape round the edge
To help the seal when it should close.
Maybe some solder to narrow the band?
Or use the iron to apply that stitching stuff
To hold a hem or two?
 
Or perhaps,
              Just rip it from my chest.
              Throw it to the flames.
              Watch it shrivel, turning black
              And then to ash.
              Who knows? I may be rewarded
              With a bird of feathered flame,
              Clutching in its talons a burning heart
              To place inside my chest.
 
Or, if not, I could use the ash
To mark my empty breast
With an X.
