A drainpipe test plug for plugging a drainpipe via an opening formed therein includes a plug seal that includes a planar front surface which faces upward in the drainpipe whenever the drainpipe test plug is in a plugging position and a peripheral annular rim. The plug seal can include a plurality of holes or a continuous channel formed into the surface of the planar front surface, or a plurality of holes or a continuous channel formed into the surface of the peripheral annular rim, or both. The plug seal holes or channels impart a degree of flexibility to a peripheral area of the plug seal to facilitate the insertion and removal of the drainpipe test plug from the drainpipe. In addition, the holes or channel in the planar front surface provide additional sealing force against the interior of the drainpipe whenever the drainpipe test plug is in the plugging position.

The present invention is directed to a device that can easily deliver water or other sources of hydration from a bottle, directly to a user during exercise without the use of a traditional hydration bladder. The present invention features a hydration device for allowing delivery of a fluid from a container with a cap with a hole. The hydration device may comprise an outer tubing affixed around the hole and an inner tubing disposed within the outer tubing. The inner tubing may extend past both ends of the outer tubing, slide freely within the outer tubing, and extend to the bottom of the container. Both ends of both tubings may be always open. The fluid may be delivered from the container through the inner tubing when suction is applied. Air may be delivered from the outer tubing to the pre-existing container to prevent collapsing of the pre-existing container.

A tube holder includes a tube clamp having a housing and a clamping mechanism. The housing has a tube entry along a major surface thereof. A first tube passageway extends from the tube entry into the housing, and a tube receiving channel is coupled to the first tube passageway. The clamping mechanism comprises a lever handle user operable to transition from a first position to a second position. A gate is coupled to the lever handle, and a tube pinch is coupled to the lever handle. When a tube is peripherally inserted into the tube receiving channel and the lever handle of the clamping mechanism is in the second position, the gate prevents the tube from exiting the housing via the first tube passageway, and the tube pinch pinches the tube so as to prevent a flow of a fluid through the tube.

A fluid control system to control fluid flow within a drainage system is disclosed that includes a cage configured to couple an interior wall of a structure of the drainage system, wherein the cage at least partially surrounds an aperture of the interior wall, and a float device configured to be encapsulated within the cage, wherein while in a resting state, the float device at least partially covers an aperture of the structure of the drainage system. In some instances, when fluid contacts the float device at a flow rate of at least a flow threshold, the float device is configured to at least partially uncover the aperture of the interior wall, or further uncover the aperture of the interior wall. The float device may be formed from a buoyant material and configured to rise from the resting state in accordance with a rising fluid level within the structure.
