How to Get Rid of a Sewer Smell From a Sump Pit
- 1). Remove the cover of the pit. Disconnect the sump pump from the electrical outlet and remove it from the pit, or leave it in so it can pump the gunk out.
- 2). Spray the walls and bottom of the sump pit with a garden hose. The pump will do its job and pump the gunk away. If your garden hose won't reach, scrape and scoop the crud from the walls.
- 3). Keep spraying until the water is clear.
- 4). Clean the walls of the pit with bleach and a scrub brush. Use as much bleach as you need to get the job done. This sanitizes the pit and slows the sour smell from returning.
- 5). Mix the bleach to a ratio of 1 oz. to a cup of water. Pour the mixture into a spray bottle and spray the walls of the pit as you scrub. You can scoop the gunk into a bucket, or use your wet-vac and suck it up if you have disconnected the pump.
- 6). Add 1 to 2 tbsp.of oil in the sump pump crock. The oil helps seal it so the smell will not come through.
