ABSTRACT:
A conduit flushing device comprising an elastomeric tubular body having one end thereof to be connected to a suitable source of water under pressure with the opposite end of the tubular body being connected to a valve. The valve is normally closed by an integral portion of the tubular body being in watertight contact with an elongated sealing member of the valve. Supplying of water within the tubular body causes the body to expand spacing the seat assembly from the sealing member permitting flow of water from the internal chamber of the tubular body and through the valve.
