All plumbing fixtures have drain traps – a bend in the drainpipe that is always filled with water. The water stops smelly sewer gases from entering your house. The traps below your sinks are replenished every time
Steps
- Remove the lid from the drain trap.
- Clear any debris from the drain trap.
- Pour half a bucket of water down the drain to refill the trap.
- (Optional) Add a few tablespoons of mineral oil on top of the water in the trap to prevent the water from evaporating.
