Toilet wax rings & seals - leak repair guide:
Here we explain how to detect and repair loose, leaky toilet base seals - why the wax ring seal is critical for sanitary toilet function and how to spot and fix a leak. We explain how to diagnose and repair problems with toilets, leaks, flushes, odors, noises, running and wasted water.
Our page top photo shows ugly staining in a toilet bowl - strong evidence that this toilet has been running, wasting water, possibly flooding the septic system, and sometimes giving bad flush performance as well. Details are below.This article series discusses the cause, diagnosis, and repair of toilet problems (water closet problems) such as a toilet that does not flush well, clogged toilets, slow-filling toilets, running toilets, loose wobbly toilets, and odors at leaky toilets.
But often we have traced a sewer gas odor in a building to two types of toilet drain connection and leak problems
Loose toilets - if your toilet wobbles on the floor it is unsafe and unsanitary.
The wobbling has compressed the wax ring intended to seal the toilet to the waste pipe, permitting sewer gases to enter the building at the toilet base, and risking leaks of sewage and water into the structure.
We have even found termite damage and rot at floors where loose toilets went un-repaired for too long.
If your toilet is wobbling on the floor both flooring repairs and a new mounting flange or closet flange may be required, depending on the extent of damage to the floor below the toilet. Details of how to make the necessary repair are at LOOSE TOILET REPAIRS where we also illustrate various toilet mounting flanges, gaskets, and seals.
Check for leaks at the toilet base - you may see stains on the floor at the base of the toilet (photo above), or in severe cases the floor may be wet or the tile or flooring may be damaged.
Don't forget to check for leak stains in the ceilings of rooms located below the toilet as well.
Secure toilets with leaky wax ring seal - new closte spud-ring - even if the toilet does not wobble on the floor, its wax ring may be inadequately sealing the toilet to the main drain waste pipe flange in the floor. Perhaps the wax ring was not installed properly, misaligned, or even omitted.
Or the toilet sealing wax ring may have been previously compressed by a loose wobbly toilet that was "repaired" simply by tightening the bolts securing the toilet to the floor, leaving the squashed old wax ring in place.
Replacement toilet seals between the ceramic under-side of your toilet and the toilet mounting flange and waste pipe can be any of the following:
A traditional wax ring toilet seal - shown above. Wax ring toilet seals, also referred to as closet ring, toilet ring, spud ring, or Oatey's Johni-Ring are sold at plumbing suppliers, building suppliers like Lowes & Home Depot, and online.
A waxless toilet-gasket such as the SaniSeal BL01 "Waxless" toilet seal (shown below) or the Fluidmaster "Better than Wax" waxless (pvc) toilet seal.
A toilet mounting-flange and toilet seal wax-ring combination package such as the Danco 10718X
Septic additives like Rid-x™ won't fix a problem with building vents nor sewer odors,
and are generally not recommended anyway - see Additives & Chemicals for septic system maintenance. Are septic products needed? Are septic treatments legal?
At page bottom you will find a list of toilet trouble diagnosis and repair articles. Actually most toilet problems are fixed easily and right at the toilet by a simple adjustment, while others may not be the toilet's fault at all, and may need more thoughtful diagnosis and repair.
Taking off the toilet tank top: Some of these simple toilet diagnosis steps require that you look into the toilet flush tank on the back of the toilet.
Just lift the top off of the toilet tank and set it carefully aside on the floor where you won't break it or trip over it.
If you leave the tank top on the toilet seat (as we did for this photo) you're asking for trouble, and also, it's a bit in the way.
Our sketch below shows the parts you'll see inside the toilet tank. You may want to refer back to this drawing while reading the details of each class if individual toilet problems listed above and how they are detected, diagnosed, and repaired.
This article describes and illustrate the different types of toilets found in buildings.

I recently put tile down and had to use the extra thick wax ring (with black rubber thing) and I have no water leaking and was about to silicone around toilet when the wind blew hard and gases leaked into the bathroom from around the toilet. What should I do? Double up on the wax rings?
You may need to use a second wax ring as you suggest.
