Air valves are required on most effluent systems to prevent trapped air from causing problems. They’ll help prevent air locks in pipe systems, water hammer from occurring and pipes from collapsing.
Most farm effluent systems will have to negotiate undulating terrain (such as ridges or hills) which can cause air to become trapped. Specialist valves are also required to prevent pipes collapsing when effluent is moving under vacuum.
WaterForce offers a comprehensive range of air release, vacuum and combination type air valves, including slow-closing and effluent rated valves.
