Method 1: Fill the fresh-keeping bag with water, tie a tight knot at the mouth of the bag to seal it, and lay the sealed fresh-keeping bag filled with water on the sewer floor drain.
There should be a certain gap between the sealing part of the bag and the horizontal surface, leaving a certain flow space for water in the bag, so that the water will level itself and the sealing effect will be good. It's OK to use a higher-grade, thicker sealable bag, or lay it flat.
Just remove the bag when you take a shower at night, and then put the bag on the floor drain after taking a shower.
Method 2:
1. You only need to prepare a garbage bag and a roll of tape. We cut off the bottom of the garbage bag so that both ends of the garbage bag are open.
2. Then we put the garbage bag into the sewer, exposing a small section, and then turned this small section over
3. Fix it with tape. That's done, then stuff the sewer pipe into the sewer (because the garbage bag is relatively soft, the water will open the garbage bag without affecting its use.) When the water is stopped, the garbage bag will shrink together to prevent the odor from returning.
