Patent ID: 10683958

Abstract:
An “Adjustable Drainpipe Test Plug Device” (hereinafter “Device”) includes a lever arm and a plug seal assembly coupled that lever arm. The plug seal assembly fully or partially mechanically seals the drainpipe when the Device is locked into one of a plurality of plugging positions through a drainpipe side opening. A positioning arm assembly is rotatably coupled to a rear portion of the lever arm to releasably engage the lever arm while a foot of the positioning arm releasably engages a bottom rim of the side opening, thereby locking the Device into plugging position. An adjustable extensible rod of the positioning arm assembly enables the foot to engage the side opening of pipes having different nominal wall thicknesses. The Device may include a through-hole passing from a front side of the plug seal assembly to a rear side, and may include a fluid fill hose sealably coupled to the through-hole.
