[[Image:Icon_pour_flush_toilet.png|right|80px]]'''A Pour Flush Toilet pour flush toilet is like a regular Cistern Flush Toilet (U.5) except that instead of the water coming from the cistern above, it is poured in by the user, instead of coming from the cistern above. When the water supply is not continuous, any cistern Cistern Flush Toilet can become a Pour Flush Toiletpour flush toilet.'''
Just like a traditional [[Cistern Flush Toilet| Cistern Flush Toilet]], there is the pour flush toilet has a water sealthat prevents odours and flies from coming back upthe pipe. Water is poured into the bowl to flush the toilet of excreta; approximately 2 to 3 L is usually sufficient. The quantity of water and the force of the water (pouring from a height often helps) must be sufficient to move the excreta up and over the curved water seal.
The S-shape of the water seal determines how muchwater is needed for flushing. To reduce water requirements,it is advisable to collect toilet paper or other drycleansing materials separately. The waterseal at the bottom 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 itis rough or textured). 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== The water seal is effective at preventingodours and it is appropriate for those who sit or squat(pedestal or slab) as well as those who cleanse withwater. It is only appropriate when there is a constantsupply 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 forboth public and private applications.Pour Flush Toilets are adequate for almost all climates. ==Health Aspects/Acceptance== = The Pour Flush Toiletpour flush toilet (or squatting pan) prevents users from seeing or smellingthe excreta of previous users. Thus, it is generallywell accepted. Provided that the water seal is working well, there should be almost no odours and the toilet should beclean and comfortable to use. ==Maintenance==
===Operation & Maintenance=== Because there are no mechanical parts,Pour Flush Toilets pour flush toilets are quite robust and rarely requirerepair. Despite the fact that it is a waterbased toilet, 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 toilet.
