[[Image:Icon_pour_flush_toilet.png|right|95px80px]]'''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 Flush Toilet, there is a water seal that prevents odours and flies from coming back up the pipe.

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 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.

Both pedestals and squatting pans can be used in the pour flush mode. Due to demand, local manufacturers have become increasingly efficient at mass-producing affordable, 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 much water 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 dry cleansing materials separatelytextured).

The waterseal at the bottom S-shape 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 water seal determines how much water is rough or textured)needed for flushing. 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.

- The water seal effectively prevents odours <br>- The excreta of one user are flushed away before the next user arrives <br>- Suitable for all types of users (sitters, squatters, wipers and washers) <br>- Low capital costs; operating costs depend on the price of water | con= - Requires a constant source of water (can be recycled water and/or collected rain waterrainwater)<br> -The U-trap can easily become blocked<br> - Requires some education to be used correctlymaterials and skills for production that are not available everywhere<br>-Pathogens are mixed with Coarse dry cleansing materials may clog the water and thus spread over a relatively large volumeseal

==Adequacy=Appropriateness=== 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==

===Health Aspects/Acceptance=== The Pour Flush Toilet 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.

===Operation & Maintenance===Because there are no mechanical parts, Pour Flush Toilets pour flush toilets are quite robust and rarely require repair. 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.
