Lately, it has been nothing but one plumbing problem after another in
my house.

My toilet valve doesn't always close completely, and will sometimes
drip-drip-drip into the lower bowl until the next flush.
Two weeks ago, the tub drain plugged up solid.
Last week my kitchen faucet fell apart.

Last night, I was waiting for a load of laundry when I caught a whiff
of musty/poo smell. I went downstairs to investigate, and found a
puddle steadily spreading from the sump crock as the washing machine
drained into it. Frickin' float came loose.

So obviously my plumbing is slowly crumbling... Should I just tear it
all out and start over, or deal with the repeated floodings and
disasters as they come?
