ABSTRACT:
A flexible pipe connector is disclosed having two female ends, each for receiving a length of corrugated pipe and creating a gravity flow water-tight seal between the two lengths of corrugated pipe. The flexible pipe connector is made of flexible, stretchable plastic material, with each female end having a receiving length with a mouth at a first end thereof and a stopping flange at a second end thereof. Each female receiving end is constructed to stretch radially outward along a substantial length of the corrugated pipe which is inserted into the mouth and receiving length, such that the receiving length exerts radially inward compressive forces against the outer diameter of the corrugated pipe effectuating a gravity flow water-tight seal. The invention also includes a male-to-female form of connector having a female end and a male end, which coupler is adapted to be used to connect a corrugated pipe to a flexible seal member of a drop box and is able to receive a speed leveling device. Additionally, a female-to-female connector for use in sealably connecting smooth-walled, hard plastic drain pipes. Clamp means are disclosed to assist the flexible pipe connector in creating a pressure water-tight seal.
