A conduit cleaning device includes a body with a central portion, a forward portion comprising a neck, and a rear portion with a hose fitting adapted for connection to an associated hose. The body includes a main flow passage that extends through the hose fitting, through the central portion, and into the neck. A rotor is rotatably supported on the neck. The rotor includes at least one rotor nozzle orifice in fluid communication with the main flow passage. A centering device is secured to the central portion of the body. The centering device includes a core and a plurality of fins that project outwardly from the core. The core of the centering device includes a mounting bore that extends therethrough, wherein at least part of the hose fitting is located within the mounting bore of the core and an annular space is defined between the hose fitting and an inner surface of the mounting bore of the core.

In a hydraulic circuit including a ball circulation pump skid, a single pump, and a set of valves in a manifold of the ball circulation pump skid, the pump and valves are operated to move all fluid in the hydraulic circuit alternately along two paths through an operative device and a ball collection capsule in the manifold, so that none of the balls ever enter the pump. The first path enables (a) ball-containing fluid flow from the operative device to the ball collection capsule and (b) ball-free fluid flow from the ball collection capsule to the exactly one pump and back to the manifold. The second path provides for (c) ball-free fluid flow from the pump to the ball collection capsule and (d) ball-entraining flow from the ball collection capsule to the operative device.

A ball circulation pump skid includes a piping manifold mounted to a base frame, having a first inlet and a first outlet each connected to a pump, and provided with a second inlet and a second outlet connectable to an external device. The manifold houses a ball collection capsule configured to permit flow of fluid and entrained cleaning balls into the ball collection capsule in a first flow direction and to permit flow of fluid and entrained cleaning balls out of the ball collection capsule in a second flow direction. Valves mounted to the piping manifold are operative to create alternately a first fluid flow path and a second fluid flow path through the piping manifold, to capture the cleaning balls in the collection capsule prior to fluid flow to the pump and to re-entrain the cleaning balls prior to fluid delivery to the external device.

A method and system for removing debris from drainage lines in high rise building uses a high pressure water line terminated by a head having one or more backwards-facing nozzles. The thrust force creates at the backward-facing nozzle(s) is sufficient to propel the head and water line vertically up a drainage line. An operates can control the head and, with the assistance of a video system used with the head, maneuver the head along the line, into single stack aerator fittings, and into and along horizontal lines connected to the single stack aerator fittings. The force of the water exiting the nozzle(s) on the head both dislodges debris in the drainage line and fittings, and urges it downstream back to the access point where the head was inserted into the drainage line.

The methods for cleaning pipes with service connections includes vacuuming therethrough abrasive projectiles first in one direction, and thereafter, in an opposing direction, with additional cleaning achieved by opening of service connection valves during vacuuming. By opening service connection valves during vacuuming, debris and moisture are removed from within the service connections. Vacuuming direction reversal removes shadow deposit areas.
