Abstract
A stilling device, especially useful in large water or sewer pipes or conduits having overhead access openings, is provided in tubular T-shape. The base of the T conveniently comprises a plurality of telescoping sections adapted to be secured together at given extended length. Openings through one side of the T base in a direction perpendicular to the plane of the T facilitate equalization of liquid level inside with the surrounding level when immersed in a water or sewer pipe or conduit. The cross-bar of the T aids retention of the stilling device in place.
