摘要

The control pit is for drainage pipe connections, and comprises a body with a base and a top cover. The body has at least one connecting union (3) for joining to a pipe, and from such unions (3) a spray pipe (11) extends inside the body (1) towards the pit cover (12). The spray pipe (11) can be flexible or rigid, and comprises a cross-profiled or screwline profiled pipe section. On the inside of the pit, the connection unit end (6) is slanting, whilst outside the pit it can be T-shaped. The angle of slant of the inside end is approx. 45 deg.
