Which toilet is right for you? 

 

Do you need an S-trap or a P-trap toilet?

Plumbing pipes for S trap toilets are in the shape of the letter S. The exit line is at the bottom of the toilet and lead directly into the floor.

With a P trap toilet, as the letter suggests, the plumbing pipe is shaped like a P and exits at the back of the toilet leading directly into wall cavity.

The reason they call it a trap, is that after the toilet has been flushed, some portion of water remains in the pipe to act as a seal to stop sewer gases re-entering the building.

 


What is the set out of the toilet?

The set out is the distance from the wall to the centre of the outlet. There are regulations on what the distances can be, so the correct measurement is required. The current modern Australian standard distance requirement is 140mm – 165mm.


Do I need a rear or bottom entry cistern?

The cistern is the storage tank for the water. A bottom entry means there is a tap on the outside of the toilet under the cistern (usually on the side). A rear-entry means the toilet is connected inside the cistern.

 


What is a trap?

Take a closer look at your sink, laundry tub or toilet. All plumbing fixtures feature a trap. A plumbing trap is simply a system of shaping pipes to stop sewer gasses from flowing back into your home or property or in layman’s terms, it stops the stink!

 


Why does it matter?

In simple terms, because space usually is a premium in bathrooms and toilets. Both types of toilet work but it will always depend on how much space you have to play with.

Step 1: Start measuring the distance from the centre of the toilet bowl to the wall. This determines whether you can fit an S-trap toilet or not.

Step 2: Measure how much space you have between the centre of the toilet bowl to the floor. This will determine whether a P-trap toilet will work.

Remember to talk to your plumbing professional when planning your bathroom and especially before purchasing new toilet suites to confirm set out distances, what type of toilet you are to have and the type of cistern you would like.

 


Moving plumbing lines can be very costly!

The reason being, if you imagine that behind walls, floors and in ceilings, there exists a complicated, interconnected highway of pipes, lines and cables. To move plumbing lines to a new location in a building or room requires a new highway to be built to accommodate the change. So, to save costs wherever possible use existing plumbing lines.
