'''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, there is 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 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.
Water is poured into Both pedestals and squatting pans can be used in the bowl to pour flush the toilet of excreta; approximately 2 to 3L is usually sufficientmode. The quantity of water and the force of the water (pouring from a height often helps) must be sufficient Due to move the excreta up demand, local manufacturers have become increasingly efficient at mass-producing affordable pour flush toilets and over the curved water sealpans.
Both pedestals and squatting pans can be used in ===Design Considerations===The water seal at the bottom of the pour flush mode. Due to demand, local manufacturers toilet or pan should have become increasingly efficient a slope of at mass-producing affordable, Pour Flush Toilets and pansleast 25°. Toilets can Water seals should be made from out of plastic or ceramic to prevent clogs and ceramic, to make cleaning easier (concrete may clog more easily if it is rough or from galvanized sheet metaltextured).
The S-shape of the water seal determines how much water is needed for flushing. To reduce water requirements, it is advisable to collect toilet paper or other dry cleansing materials separately. The waterseal at the bottom of the Pour Flush Toilet or pan should have a slope of 25 to 30°. 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 rough or textured). The optimal depth of the water seal head is approximately 2cm 2 cm to minimize the water required to flush the excreta. The trap should be approximately 7cm 7 cm in diameter.

===AdequacyAppropriateness=== The water seal is effective at preventing odours and it pour flush toilet is appropriate for those who sit or squat (pedestal or slab) , as well as for those who cleanse withwater. It Yet, it is only appropriate when there is a constant supply of water available, and where the infrastructure is available or can be built to manage waste water. The Pour Flush Toilet pour flush toilet requires (much) less water than a traditional cistern Cistern Flush Toilet. However, because a smaller amount of water is used, the Pour Flush Toilet 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. Pour Flush Toilets are adequate for almost all climates. Pour Flush Toilets are especially appropriate in densely populated areas where dry handling of excreta isn't socio-cultural appropriate.
===Health Aspects/Acceptance===
The pour flush toilet (or squatting pan) prevents users from seeing or smelling the excreta of previous users. Thus, it is generally well accepted. Provided that the water seal is working well, there should be almost no odours and the toilet should be clean and comfortable to use.

Despite the fact that water it is used continuously in the a waterbased toilet, it should be cleaned regularly to maintain hygiene and prevent the build up buildup of organics and or/stains. To reduce water requirements for flushing and to prevent clogging of the Pour Flush Toilet, it is recommended that dry cleansing materials and products used for menstrual hygiene be collected separately and not flushed down the toilet.
