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.
