    By the end of this blog post, you will know the difference between an S-Trap and a P-Trap, a wall hung and rear water inlet, along with how to measure the setout and so on. Already a toilet know it all? Skip to the bottom of this page and fill in our toilet selector form. The set out of a toilet outlet refers to the outlet drainage point location. S-Trap Pans An S-trap is where the toilet waste pipe connection is in the floor picture the s on its side to reflect the trap that holds the water seal.

    The set out for an S-trap is the distance from the wall to the centre of the pipe penetrating the floor. Again picture a P on its side. The set out of a P-trap is a height measurement from the floor to the centre of the waste pipe.

    This measurement should be taken in height and from the wall that is running parallel with the waste pipe. Both measurements to the centre of the pipe. Vented Pans A vented pan is a toilet pan that has a 50mm vent pipe coming off the back of the trap, normally travelling up and through the roof to the atmosphere.

    Since then we have learned more about hydraulics and the standards have changed, meaning that often your vented pan can be replaced with a non-vented so long as the toilet point is within 10 meters of the main sewer line.

    This measurement is taken from the centre of the waste outlet to the left or the right, and height from the floor to the centre of the water point. This point can generally be easily altered during a renovation, however, if completing a straight swap over may require additional work. Back Entry Water Connection Back Water Entry Back entry water supply is when the water supply isolation valve and pipework is located inside the toilet cistern.

    This option is normally only applicable to close coupled and back to wall suites. It makes for a very aesthetically pleasing finish as it means all pipework is covered. It also makes cleaning a lot easier as there is no non-ceramic area for dirt etc to collect.

    S trap Vs P trap Toilet What’s The Difference

    The Hidden Danger A hi-tech toilet is likely to have a trap built into the lower cistern, so these toilets are often called p-traps.

    A low-level flush may result in a dry bowl when the trap is correctly installed and vented. Older plumbing typically had an L shaped bend followed by a horizontal pipe leading to another vertical pipe called a waste stack.

    This means that of all the water taken up by the toilet bowl, only some of it gets discharged out through, not down, this waste pipe which is why they squat on emptying their bowls after flushing.

    Toilet designers and manufacturers recommend that both pipes be as straight as possible and joined together with two traps, one within each of those sections rather than just one just before it.

    This is the general design for most toilets. As far as toilet tank connection, you may find that some toilets have a p trap and many do not. This is up to the individual manufacturer. What is a P Trap Toilet? P traps are plumbing fixture that is used in many homes and other buildings.

    The most important function of toilets with p traps is trapping water within its bend so that sewage gases cannot enter through the drain pipes leading out of the building. An easy way to think about this is how two rivers can flow parallel to each other with no place for water to flow between them. Ap trap is different to a p trap. The p trap toilet traps water within the U-bend formed by the pipe and allows wastewater and greywater to pass through freely without letting sewer gases escape from the trap.

    If there was no water within the S-shaped curve, sewer gases would still be able to seep up through drains with force, even after flowing down from high points such as a roof downspout. Basically, that means that anything can flow down the smooth curve of the trap toilet so long as there is enough pressure behind it to overcome gravity. You can tell if your p trap toilet needs repair or replacement by visualizing whether or not water remains within the S-shaped bend at all times when you check in with it.

    Before buying a new one, measure the distance from the wall to the centre of the waste outlet. A clear sign that something has gone wrong in this department is if you notice slow drainage coming from your showers and sinks over time rather than all at once. This is because the p traps have failed to do the job of trapping water within its bend, allowing it to run away into the bathroom sewage plumbing system. Trap Waste Pipe Average Height The average height of a trap p style in a toilet is around 30 to 40 centimetres above the floor.

    The taller the p-trap is, the more likely it may be to function properly because gravity may allow wastewater and greywater to flow through without needing outside help to push them along. Replacing a broken p trap toilet is relatively simple, it just takes some elbow grease and a little bit of know-how. A p trap toilet replacement may include new p trap plumbing with U-shaped bends that provide all the required stopping power when it comes to preventing sewer gases from entering or leaking into your home.

    How does P Trap Toilet Work? Trap Styles on Modern Toilets Trap designs vary widely on modern toilets. There are many shapes to fit into tight spaces or break up the lines of what would otherwise be a square looking toilet. The trap can also serve as an armrest, keeping your elbows out of urine-splashed water. Wall Hung Bathroom Toilet Wall hung toilets can also have their traps integrated into the base of the toilet, thus the wall hung option is serving as a pooling point for water that creates an inviting space for your toes to dip into at the end of a long day.

    Close-coupled Traps Close coupled or double trap p-style design is a more modern look for a bathroom toilet, and it doubles the chance of a leak occurring right before you or your guests reach for the flusher.

    Close-coupled traps on modern toilets vary widely, and they all serve their own purposes in creating a more aesthetically pleasing look for bathrooms both large and small. Modern Drain Pipe Venting The flow of air around the drain—pipe of your bathroom toilet is very important, no matter how old it is. Types of Toilet Suites There are many types of toilet suites, even though the standard fixture is still widely in use.

    Designers have put their unique stamp on this important fixture, especially in terms of how it flushes and cleans itself. For example, waterless toilets create less wastewater in an eco-friendly way by using fewer gallons per flush. Waterless toilets use less water per flush, which can help reduce your water bill. They have been tested and approved for homes in the US. In Australia however, they are not permitted for use in residential areas.

    Smaller Water-saving Toilets? Some designs have smaller footprints as well as less water usage per flush. They tend to be more expensive but can also be used in commercial settings such as public restrooms where there is a cheaper installation cost associated with them. It receives the clean water from your water main, then sends it into the bowl or onto the rim of your toilet for flushing purposes.

    The volume capacity of these fixtures varies widely with models. Toilet Tank Connections Toilet tanks are usually connected to low profile floor plumbing, which is typically made up of plastic ABS pipes rather than metal ones.

    When this occurs, you often have no choice but to install a p-trap that looks ugly or stands out in your bathroom space. I have even seen these traps fitted below ground level inside homes where the waste outlet line drops down then goes straight back up again. With the waste line running through a finished basement, for example, this means that your basement floor can potentially be covered entirely with tile.

    The Hidden Danger The problem seeing as you have no option but to install an ugly looking p-trap in your bathroom, with an inefficient water seal, the amount of water that may evaporate or keep seeping into your soil causes all sorts of damage. Some ABS traps connected using push fittings, which are leaking allow for contaminated water to escape unseen.

    If you were to look at this setup without knowing what was behind the wall originally, you would think everything was fine since there are no leaky taps or toilets insight.

    This however is one of many installations similar to this and it only takes a bit of water to create a huge amount of damage.

    One fix is to pour some RV antifreeze into the drain. Basement toilets are another frequent offender. These are typically found in old Minneapolis and Saint Paul homes, and it consists of a toilet sitting out in the middle of the basement, with no privacy offered.

    If you have an old toilet in your basement with no water line connected, have it removed and have the opening to the sewer capped off. Infrequently used bathrooms are the final common offender.

    In larger homes with guest bathrooms that never get used, the water in the sink, toilet, tub, or shower can evaporate. As with floor drains, the fix is to pour some RV antifreeze into the fixtures or remember to run some water through them every few months. Another way for traps to lose their water seal is through siphoning.

    Some are even lethal in high enough concentrations! Plumbing traps protect your home from the risks that come with nasty sewage odours by ensuring that harmful gases and waste — shudder! Every time you flush, water goes down your toilet. This water creates a seal that prevents gas from passing back into your bathroom.

    Fun fact: thanks to the bend in the trap, they also have a tendency to catch heavy objects that inadvertently fall in to the loo. When we talk traps, in our experience there are two types that appear in the vast majority of Melbourne homes and toilets in particular : S-traps and P-traps.

    The first is the S-trap. Generally favoured for ground floor installations of floor mount-types of toilets toilets where the pipe goes through the floorthis pipe got its name — how else? As one of the oldest types of trap on the market, S-traps are extremely prevalent.

    However, that also means that there are some sides to the design which are a little bit dated.

    This can lead to the water level dropping, opening up gaps for sewer gasses to creep in. What about P-traps? Imagine an S-trap, only instead of going down-up-down to create an S-shape, it goes down, curves up, then becomes straight, creating an open P-shape.

    More commonly installed in top floors and in wall-mounted toilets, P-traps are more commonly used in kitchen and laundry sinks. P-traps are generally considered by most to be more effective and consistent in maintaining water trap compared to S-traps.
