The sewage water flushing hydrant is an adapted freeflow underground hydrant. Through the free medium pipe in opened position, this flushing hydrant allows the efficient introduction of flushing water into the sewage pressure pipe, while sewage water can be removed, for example, when a temporary bypass pipe is to be installed.
The sewage water flushing hydrant is provided with a Storz B coupling of stainless steel.
The flushing hydrant is not provided with a drainage mechanism to avoid sewage water from seeping away. Shut-off is effected via a teflon-coated shut-off blade of stainless steel.
Q = 153 m³/h water at 1 bar pressure difference
Min. cross section: 62 mm without drainage mechanism
Straight-through bore 62 mm (Storz B)

It is possible to open the B-coupling with a special Hawle tool (available on request)
