Things You'll Need
Weeping tile is a type of piping used for underground drainage. Water above the weeping tile flows into it and gets drained into a storm sewer or sump pump. It's normally used to prevent basements from being flooded. Unfortunately debris is left behind causing the drain to backup leaving a bad odor and in some cases overflow onto the basement floor. Flushing or cleaning the weeping tile can be done with soapy water to remove the odor and debris; but a water source must be present in your basement such as a laundry sink or washer faucet.
Block the sewer at the floor drain. It's located under the catch basin, where the water collects. The easiest way to do this is with a plunger. The plunger must be larger in diameter that the drain at the bottom of the catch basin. Firmly wedge the plunger's head into the drain.
Hook up a hose to your water source. Most people connect it to their washer faucets.
Fill the catch basin with water and liquid soap. The catch basin and weeping tile must be completely filled. Do not allow the water to overflow.
Allow the soapy water to sit for 30 minutes. This will neutralize the odor.
Remove the plunger and the water will drain.
Repeat this process a few times and then rinse out the basin with clean water to remove any soap residue.
The plunger's handle should be long enough to reach.
