temporary drain block

The cheapest and easiest way to temporarily block a drain is to take a plastic grocery bag, push the bottom of the bag into the drain opening aprox. 2 to 6 inches depending on the drain size. Stuff crumpled newspaper into the (now plastic bag lined) drain pipe to get an airtight seal. Be sure to leave about half the bag hanging out of the drain for easy removal. If the plug is hard to pull out pour water into the bag to wet the newspaper.

You lost me there, can you explain in more detail? Maybe with pics? I'm intrigued, but I'm just not getting it.

Thanks!

Hi GlassGeezer,
Sorry for the confusion. Am assuming you want to prevent sewer gas from getting into your house when temporarily disconnecting a sink, toilet or whatever. Take a plastic grocery bag or small trash can liner and push the bottom end of the bag into the drain opening about 2 to 6 inches depending on the size of the drain pipe. Push crumpled newspaper into the open end of the plastic bag to get an airtight seal. If the plug proves hard to remove just pour water into the bag. The crumpled newspaper will shrink allowing you to easily pull out the plug. If this still sounds confusing I'll be glad to send photos.

Hey,
thanks for the tip and its complete explanation.
