I have leaking at the base of my toilet each time it flushes, we replaced the wax gasket but leaking still persists. There are no cracks at the base. Any ideas what could be wrong?

 

Where specifically do you see water?

It could be leaking from the tank... Get a bright flashlight and look around....

Possible the toilet was not set correctly...

 

Wax rings are available in different sizes and unfortunately they can easily get damaged when placing the toilet. When you placed the toilet did it go "clunk" down flush on the floor or did you have to sit on the toilet to squish the wax ring?

 

I would replace the wax seal again and let the bowl fill but do not flush. If you see any leaking at that point, you know you have a tank or bowl leak, which could be a connection or a crack in the fixture. If no leak after a day or so, then start flushing and see what happens.

 

Maybe your Toilet Flange is too low...You'll have to measure from the top of your existing flange to the level of your finished floor. I found this product named Set-Rite about 4 years ago and swear by it now...basically because most toilet flanges, I have seen, are not installed correctly. The correct way is to have the toilet flange lip on top of the finished floor, that way the cast opening in your toilet is inside the flange and a single wax ring will work as it is supposed to. Don't let anybody tell you that you can stack wax rings... The Set-Rite website is at... www.set-rite.com
