A P-trap toilet is also known as a P-trap because of the shape of the plumbing underneath it. This type of toilet has a P-shaped curve in the plumbing pipe that helps to prevent sewer gases from entering the bathroom. The P trap is commonly used in sinks, showers, and toilets.
There are two main types of P-trap toilets: the one that flushes water and the one that doesn’t flush water.
Flush Water P Type Toilet:
These are modern P-trap commodes that flush using water. When the toilet is flushed, the water travels through the P-trap and into the waste pipe, carrying away the waste. The trap seal is replenished with every flush. However, the amount of water used for each flush depends on the toilet’s design. There are low-flow, standard, and high-flow P-trap toilets. The water-efficient models help conserve water, making them environmentally friendly.
Non-Flush Water P Type Toilet:
These are portable chemical toilets that don’t flush with water. Instead, they use a powerful chemical solution to break down waste and eliminate odors. The chemical tank is sealed, preventing waste and gas from escaping. These toilets are designed to be used in locations without a plumbing connection. They are emptied and cleaned by the user or professional service when full.
Other classifications of P-type toilets are based on their mounting and flushing system.
Conventional Flushing P Trap Toilet:
This is a non-water-saving commode that uses a gravity-assisted flushing system. The system is driven by the weight of water in the tank. When the toilet is flushed, water empties from the tank into the bowl. Most western-style toilets are designed with a water-efficient flushing system that uses less than 1.6 gallons of water per flush.
Wall-Mounted P Trap Toilet:
This commode is mounted to the wall, and the plumbing P trap is also located within the wall. The waste pipe and water supply line are hidden from view. These toilets are popular in modern bathrooms because they make the floor easy to clean. They also create the illusion of more space because the toilet is not sitting directly on the floor.
High-Efficiency P Trap Toilet:
This type of commode is specifically designed to use less than 1.28 gallons of water per flush. They are perfect for eco-conscious homeowners looking to reduce their water bills and environmental impact. These toilets often use advanced flushing technology, like dual-flush systems or powerful siphon jets.
Compact P Trap Toilet:
These toilets are designed for small bathrooms or powder rooms. They have a smaller footprint without compromising performance. They are ideal for tight spaces like RVs, boats, and tiny homes.
P-type toilets are also commonly referred to as close-coupled toilets. Below are some of their features and functions.
Toilet Bowl
It consists of a close-coupled cistern and a ceramic pan. The toilet is also known as the water closet. The water closet is the part that receives and stores human waste until it is flushed away. The water closet is also known as the toilet seat.
Toilet Seat
The toilet seat is part of the WC that provides a comfortable place for humans to sit when using the toilet. It consists of two main components: the seat and the lid. The seat is the part people sit on, while the lid is used to cover the toilet when not in use.
Flushing System
The flushing system is responsible for the removal of human waste from the toilet bowl. It consists of a cistern, a flush valve, and a release mechanism. The cistern stores water, and the flush valve controls its release into the bowl. The release mechanism is the part activated by users to initiate flushing.
Tank
The tank is responsible for storing water that is used for flushing the toilet. It is also known as the cistern. Inside the tank are components like the fill valve, flush valve, and siphon jet. The fill valve controls the entry of water into the tank after a flush, while the flush valve regulates water release during flushing. The siphon jet creates a powerful flow of water to ensure the bowl empties completely.
Outlet
The outlet is an integral part of the P-type toilet. It is a curved pipe that connects the toilet bowl to the drainage system. Once human waste enters the bowl, it travels through the outlet and is directed into the home or public place's sewage or drainage system. The outlet is responsible for the proper and safe disposal of human waste.
Flush Handle
The flushing handle is a lever or button that people press to initiate the flushing process. It is usually located on the top or side of the cistern. When pressed, it lifts the flush valve, allowing water to rush into the bowl and remove waste. The flush handle is designed to withstand repeated use and is easy to operate.
Concealed Cistern
A concealed cistern is a system that hides the flushing mechanism inside the wall. This makes the tank less visible and provides a more aesthetic appearance. Even though it is concealed, the flushing power remains the same.
Commercial Restrooms:
Conventional and smart toilets are often seen in commercial settings, such as office buildings, shopping malls, and restaurants. Their unique design adds a modern touch to the restrooms. The functionalities of the smart toilets, like touchless flushing and integrated bidets, enhance hygiene and reduce the need for manual contact with surfaces.
Public Facilities:
P-trap toilets are commonly found in public restrooms in parks, airports, museums, and other public spaces. These toilets are easy to maintain and can be connected to underground plumbing systems. Some public facilities also have smart toilets that offer features like self-cleaning bowls and odor removal functions to ensure cleanliness and comfort for users.
Residential Bathrooms:
Both conventional and p trap commode with flush smart toilets are popular in home bathrooms. Their designs are versatile, complementing different interior styles, from traditional to modern. Smart toilets provide luxury features, such as heated seats, adjustable water temperature, and air dryers, enhancing the overall bathroom experience.
Luxury Hotels and Resorts:
Many high-end hotels and resorts offer guests an unforgettable bathroom experience by installing luxury toilets. These toilets often have advanced bidet functions, seat warmers, and built-in deodorizers. The toilets' sleek and sophisticated design adds to the ambiance of a luxurious and relaxing atmosphere.
Healthcare Facilities:
Smart toilets with touchless operation and hygienic features are commonly found in hospitals and clinics. These toilets minimize the risk of germ transmission, which is critical in healthcare settings. Some models also include functions like anal and genital washing, which are beneficial for patients with limited mobility.
High-Tech Homes:
In homes where technology is highly valued, toilets that are equally advanced can be expected. These toilets can be controlled via smartphone apps or voice-activated assistants. Other features include automatic lid opening and closing, seat heating, and personalized flushing settings.
Eco-Friendly Establishments:
Some organizations, businesses, and homes that prioritize environmental sustainability opt for toilets that use less water. Fortunately, p trap toilets with eco-friendly features are now available. These include dual-flush systems that allow users to choose the amount of water needed for each type of waste.
Consider the Flush System
The business owner should look closely at the flush system of each P-trap commode. There are single- and double-flush options. The latter allows users to choose their desired flush volume, while the former releases a fixed amount of water. The business owner should consider the water efficiency and the effectiveness of the flush to ensure it meets the demands of their target customers.
Compatibility with Plumbing
Each type of toilet has its unique installation requirements. For instance, the S-trap commode is ideal for homes with plumbing systems installed close to the floor. In contrast, the S-trap P-Flush toilet is suitable for plumbing systems installed on the wall. The business owner must carefully consider the plumbing design of their target customers to ensure they select a model that is compatible with it. The last thing a business owner wants is to purchase a toilet model that cannot be installed in a particular plumbing system.
Comfort and Design
The business owner should choose a P-type toilet design that will be comfortable for users. They should pay attention to the height and shape of the toilet bowl. An elongated bowl offers more comfort than a round bowl. However, the round bowl has a space-saving feature. The business owner should also consider the sleekness of the toilet design. A more modern design will appeal to more customers.
Quality and Durability
Toilets are exposed to harsh conditions and elements, so it is important for the business owner to choose models that are built with high-quality materials that will withstand wear and tear. They should choose toilets that are constructed with durable ceramics and quality chrome fittings.
Consider the Size
The business owner should carefully consider the dimensions of the restrooms they intend to equip with their selected toilets. If they have sufficient space, they should consider getting commodes with wider seats and larger bowls, which provide more comfort. However, if they are working with a small space, they should get compact toilets that will fit into a small area.
