I have a freeze proof faucet on my house that leaks back through the shaft
at the handle. I replaced the rubber seal at the other end. That isn't the
problem. It's the packing but I was told the packing in these faucets can't
be replaced because they are pre-formed. Any thoughts on this? Can I leave
the old packing in place and wrap additional new around the shaft and
tighten it down?
