Vacant winter house: drain traps

I read the FAQ on winterizing, but this topic didn't get much coverage.

In a 5 month absence, I'm pretty sure the sinks, baths, and toilet traps will end up uncovered as the water evaporates. I know some people say to pour vegetable or mineral oil in, or RV antifreeze.

What do you do? (Other than have someone stop by to keep them full).

  • Be aware that if you empty the traps (or they dry out) there is a possibility the house will fill with toxic and potentially explosive sewewr gas. Which also stinks, btw. Odds of someone being poisoned or house exploding are almost, but not quite, zero. But stink, oh my will it stink.
