The Toilet - A Basic Tutorial

The humble commode. Not the most exciting topic for a blog post, but let me tell you, it wasn't a boring experience taking this thing apart and putting it back together. For those of you who have never had the fun of replacing a wax donut, let me tell you all about it.

It is sticky... That's about it. Like, really, really sticky. See, in order to trap all those noxious sewer gases out of your bathroom, there is what is called an "s trap" in the toilet, which is basically just a curve in the pipe. There is always water in the trap, which keeps the odor / gases out. Observe:

Toilet removed, wax donut still in place

Wax removed (mostly)

Anyway, when you flush, the water flows from the tank above into the bowl, pushing the water out the trap and down the drain. A wax "donut" is then used to seal the toilet to the pipe below the floor. If the wax seal breaks down, you get leakage, which is gross (see below). To replace it, you first need to scrape off the old wax and get it super clean. Hence...sticky.


Before you can even get it off, you need to shut off the water, then flush to drain the tank. What I should have done at that point was remove the pipe leading to the tank, and catch the remaining water in a cup... You know, instead of trying to scoop it out of the tank and using a ton of paper towels. Lessons learned.

Anyway, once that's done, taking the tank off is simply removing two bolts. Then there's simply no way around it, you have to scoop out the bowl with a cup. Then you remove two more nuts, rock it off the floor bolts, and you're good to go (you may need to cut the caulk along the base, but if you're doing this, it's probably shot, so you won't need to).

After you clean off the old wax, replace it with the new donut you bought, and reattach everything in reverse, and caulk a nice clean line along the base. Easy peasy.

Anyway, that was my Saturday morning adventure a few months ago. Now we have a nice, clean toilet with a working seal. Woo hoo!
