Freeflow underground hydrant "height adjustable"

Thus the underground hydrant can be adapted to the level of the road and/or of the surrounding terrain even when installed. Depending on the version, it can be adjusted between 300 to 550 mm. The medium pipe is locked via a gripping mechanism, with the telescopic operating tube being safely held via the coupling plate.

Analogous to the standard version of the freeflow underground hydrant shutting off is effected via a shut-off blade of stainless steel.
