1 common cause of sewer smell in the toilet and how to eliminate it

One of the reasons for the smell from the sewer into the room is the corrugated adapter with cilia (petals), which connects the toilet to the riser tee. Most often, such an adapter is simply inserted with cilia into the tee and left in that position.

During operation, the cilia of the adapter stick together and sink over time, as a result, the tightness of the connection is broken, which is the cause of the smell from the sewer. Even the petals of the new corrugation no longer create a tight seal with little effort.

You should not waste time trying to cover the joint with the same silicone or similar materials. The problem can be solved more simply and permanently.

How to eliminate sewer smell

From the 110th pipe we cut a ring with a width equal to the distance from the penultimate petal to the beginning of the pipe. In our case it is 4.5 cm.

We put the resulting ring on the petals of the corrugation until it stops in the pipe and make sure that the last eyelash remains free.

Carefully insert the adapter with the ring into the riser tee until it stops, making sure that the o-ring is in place.

To ease the effort, you can use a special lubricant for assembling PVC pipes or just soapy water. Before installing the toilet, insert your hand into the adapter and make sure that the eyelash is not wrapped. This simple life hack will once and for all eliminate one of the causes of sewer odor.
