Portable toilets with pressure vent valve
Pressure vent valve
— a valve that allows you to safely relieve pressure from the lower tank. This feature is found mainly in chemical toilets (see “Operating principle”). Its necessity is due to the fact that the lower tank is usually tightly closed during unused time, and the reaction between waste products and chemicals occurs with the release of gases. This is not critical during use; however, if the lower cleaning tank is removed and opened without relieving pressure, accumulated gases may violently escape from the drain opening along with the contents splashing. To avoid this, a special valve is provided that releases only excess gases and does not allow the contents to get out.| pressure vent valve | clear | Save List |
