24. Brass Backflow Valve

Also called a backwater valve, brass backflow valves are installed in sewer lines and designed to permit sewage or liquid flow only in a single direction which is out of the property. When there is heavy rainfall, the tendency of overwhelmed sewer lines creating issues is high. However, this valve works by ensuring there is no sewage flowing back into the property at any time.

Working Principle

Within the brass backflow valve, there is a small flap. This flap is mostly open to allow water to go out of the property as well as makes it possible for other sewer gases to go out. On each side of this small flap there are small floatation devices. So, when sewage or water begins to flow backwards into the property, these devices initiate a lifting up and closing of the flap.
