Just [[Image:Icon_pour_flush_toilet.png|right|80px]]'''A pour flush toilet is like a traditional regular Cistern Flush Toilet(U.5) except that the water is poured in by the user, there instead of coming from the cistern above. When the water supply is not continuous, any Cistern Flush Toilet can become a water sealthat prevents odours and flies from coming back upthe pipepour flush toilet.'''
Just like a [[Cistern Flush Toilet | Cistern Flush Toilet]], the pour flush toilet has a water seal that prevents odours and flies from coming back up the pipe. Water is poured into the bowl to flush the toilet of excreta;approximately 2 to 3L 3 L is usually sufficient. The quantityof water and the force of the water (pouring from aheight often helps) must be sufficient to move the excretaup and over the curved water seal.
Both pedestals and squatting pans can be used in thepour flush mode. Due to demand, local manufacturershave become increasingly efficient at mass-producingaffordable, Pour Flush Toilets pour flush toilets and pans. Toilets can be made from plastic and ceramic, or from galvanized sheet metal.
===Design Considerations===The S-shape water seal at the bottom of the water seal determines how muchwater is needed for flushingpour flush toilet or pan should have a slope of at least 25°. To reduce water requirements,Water seals should be made out of plastic or ceramic to prevent clogs and to make cleaning easier (concrete may clog more easily if it is advisable to collect toilet paper rough or other drycleansing materials separatelytextured).
The waterseal at the bottom S-shape of the Pour Flush Toilet orpan should have a slope of 25 to 30°. Water seals shouldbe made out of plastic or ceramic to prevent clogs and tomake cleaning easier (concrete may clog more easily if itwater seal determines how much water is rough or textured)needed for flushing. The optimal depth of the water sealhead is approximately 2cm 2 cm to minimize the water required toflush the excreta. The trap should be approximately 7cm7 cm in diameter.

===Appropriateness===
The pour flush toilet is appropriate for those who sit or squat (pedestal or slab), as well as for those who cleanse with water. Yet, it is only appropriate when there is a constant supply of water available. The pour flush toilet requires (much) less water than a traditional Cistern Flush Toilet. However, because a smaller amount of water is used, the pour flush toilet may clog more easily and, thus, require more maintenance. If water is available, this type of toilet is appropriate for both public and private applications.
==Adequacy=Health Aspects/Acceptance=== The water seal is effective at preventingodours and it is appropriate for those who sit or squatpour flush toilet (pedestal or slabsquatting pan) as prevents users from seeing or smelling the excreta of previous users. Thus, it is generally well as those who cleanse withaccepted. Provided that the water. It seal is only appropriate when working well, there is a constantsupply of water available, should be almost no odours and where the infrastructure is available or can toilet should be built clean and comfortable to manage waste wateruse.
The Pour Flush Toilet requires===Operation & Maintenance=== (much) less water than Because there are no mechanical parts, pour flush toilets are quite robust and rarely require repair. Despite the fact that it is a traditional cistern Flush Toilet.Howeverwaterbased toilet, because a smaller amount it should be cleaned regularly to maintain hygiene and prevent the buildup of stains. To reduce water requirements for flushing and to prevent clogging, it is recommended that dry cleansing materials and products used,for menstrual hygiene be collected separately and not flushed down the Pour Flush Toilet may clog more easily and thusrequire more maintenancetoilet.
