In my mail today, this timely reminder from Roto-Rooter:
Pumpkin Carvers Beware!
Never put pumpkin pulp into drains, toilets or garbage disposals. The stringy and sticky gunk is ideal for clotting drains and doesn’t grind thoroughly. Wrap the waste in newspaper and discard in a trash can or compost pile.
I know from experience that having the Roto-Rooter man visit is an expensive adventure. In this case, prevention is worth the effort.
