The Structure of a Typical Home Toilet

Virtually all toilets are made of porcelain. Plus, there’s all the hardware to hold the toilet in place and make it function. A lot of people have never looked at how this simple yet sophisticated fixture works. So, we’ll explain.

Tank Flush and Refill

The Tank

The tank is the part of the toilet that stores approximately 7.5 litres of water needed for one flush. This water is stored in the tank. It would take too long for this amount to flow through the water supply pipes for each flush.

The Flush Mechanism

Flushing the toilet starts when you push down the handle or button. If you were to remove the lid and look inside the tank, you’d see that pushing the handle lifts a valve to release the stored water into the toilet and empty the accumulated waste. It swishes down the sides of the bowl to clean them.

The Refill Mechanism

When the water in the tank drops low enough, the toilet float (the balloon-like device in the tank) drops onto a lever, thereby opening the freshwater valve to refill the tank. Once the float actually floats back up to a certain point, the water shuts off.

Bowl Rim and Siphon

The Bowl

You look into the toilet bowl a lot more than we look into the tank. Do you know how the tank works, though? If not, keep reading!

The toilet bowl, of course, is where the waste goes. The bowl would hold about twice as much water as the tank, but, unless it’s a blocked toilet, the bowl never fills more than about halfway. 

The Rim

The toilet rim is simply the top of the bowl. It’s where the replaceable toilet seat and lid are attached.

The Siphon

The siphon is the mechanism that keeps the bowl’s water level consistent. You can tell it’s working by pouring water into the bowl and noting that this doesn’t change the water level. The siphon naturally keeps the water in the bowl at its level. This is why you can still flush your toilet, using a bucket of water, when the plumbing has been shut off.

The Drainage System

The Drain

A toilet’s flapper valve opens when the flush handle is pressed down. This valve opens into the toilet’s P trap (or an old-style S trap). 

The water and waste then travel through a pipe that’s connected to a shared drain line, then the stack (the home’s main drainpipe), and on into the sewer or septic system. 

In many ways, a toilet is a perfect machine. It takes no fuel, and unless there’s a clog, it does its intended job every time. 

Flushing a toilet is an effect of gravity and water pressure. 

So, what causes a blocked toilet?

How Toilet Clogs Form

A toilet clog forms when either the toilet’s trap or its drain line is jammed with substances that have become too dense to pass through. Toilet drains often start to clog when too much toilet paper or paper hygiene products are flushed at once.

Be aware, though, that not every clog causing a blocked toilet is necessarily in the toilet itself — or even originated in the toilet. Many drains feed into the same drain line, and any one of them (the kitchen sink, for example) might be the cause of the blockage. Tree roots in outside pipes further down could be to blame as well.

Although some water might pass through a clog at first, eventually, the addition of additional solid waste will stop the flow. With nowhere for the water to go, the bowl fills, possibly until it overflows.

How to Unclog a Toilet Yourself

There are ways to unclog a blocked toilet yourself, the most common of which is using a toilet plunger. You can also wear rubber gloves and reach in with your hand and maybe a bent coat hanger to try and pull out the clog.

You can also try to break up the clog using baking soda and vinegar. First, make sure the water level in the bowl is about half. Then, pour in 250ml of baking soda. Follow this by gradually adding 250ml of vinegar. Allow it to fizz for at least 20 minutes.

If these strategies don’t clear your blocked toilet, no problem. You should definitely give us a call.
