Problems with your toilet aren't fun to handle, especially when they're creating an unpleasant stink! If your toilet emits an unpleasant smell when flushing, then you've probably attempted to look into the bowl of your toilet to find out where the issue originates. The most frequent source of the problem isn't anything to do with the toilet but rather the way it's attached to the flooring.

To eliminate it, examine the wax ring around the base of the toilet. If the ring's surface isn't properly sealed to the floor, air that is trapped within the plumbing can leak into the toilet when it is flushed. This can be particularly problematic with the vent that is the primary one if it's blocked too.

When water is flushed down a drain, it is required to force any air inside the pipe to the side. When the wax seal, as well as vents, work well, the air is able to flow through the pipe and then out through the vents without difficulty. But, if either or both of these components are in depreciation, the air will have no other option but to exit through the base of the toilet.

How do you change the wax seal?

The first step is to assess the extent to which the seal is broken in order to repair the seal made of wax to your toilet. In some cases, sealing the seal using caulk or silicone can be sufficient to make an effective fix in the short term. To properly ensure the sealing of the toilet, you'll be required to remove the toilet, empty it, and then move the toilet.

• Clean the toilet. In order to empty your toilet, switch off your water source to the toilet, and flush the tank until dry. It is likely that you will need to employ a towel or sponge to absorb any water that flushing does not remove. There are also those who have had success plunging the toilet to make sure the water is completely drained.

• Separate the toilet. A bucket is available to collect any remaining water out of the water supply pipe from the tank of the toilet and then remove the hardware from the bolts used to mount it to the floor. Be cautious when completing this task since heavy pressure could cause damage to the flange of the toilet anchor.

• Remove the toilet. Set the toilet far enough away from the work area. We recommend putting the lumber or similar blocks under the area where the toilet will be installed to guard the drain of the toilet. Make sure the toilet's base is parallel to the floor when moving the toilet in order to prevent any sloshing in your drain.

• Take off the wax rings. Wearing disposable gloves, take off the wax ring, then clean the area with the putty blade or mineral spirit. Make sure you plug the drain at this point by using either a towel or even rags (large enough to ensure that it does not fall into the drain). This is essential to stop sewer gas from getting into the space.

• Once the toilet flange is removed and put the new wax ring. Place the new wax ring tightly, making sure not to press enough that it alters the shape of the ring.

• Install the toilet, screw it onto the flooring and then reconnect to the supply of water. Give the toilet some flushes to verify whether the new wax rings are working.
