Abstract
The present invention provides methods and systems for sealing at least one leak in at least one of at least one premise-side pipe and a premise-side pipe network, the method including passing at least one of a pig train and a sealant composition under pressure along at least one of said premises-side pipeline and at least part of said premises-side pipe network such that a portion of the sealant composition enters at least one leakage site to seal and cure the at least one leak on said premise-side.

1-24. (canceled)
A method for sealing at least one leak in at least one of a premise-side pipe and at premise-side pipe network, the method comprising:
- a. activating a pressure control system for controlling a pressure in said premises-side pipe network, the pressure control system comprising at least one flow meter configured to measure a liquid flow rate and at least one valve for controlling said pressure;
- and
- b. passing at least one gel pig and a sealant composition comprising fibers under pressure along the premise-side pipe and at least part of said premises-side pipe network such that a portion of said at least one gel pig and said sealant composition flows at said pressure and enters said at least one leakage site to seal said at least one leak.
A method for sealing a leak in a premise-side pipe network, the method comprising:
- a. activating a pressure control system for controlling a pressure in said premises-side pipe network, the pressure control system comprising at least one flow meter configured to measure a liquid flow rate and at least one valve for controlling said pressure;
- and
- b. passing at least one gel pig and a sealant composition comprising fibers under pressure along a first pipeline to said premises-side pipe network at said pressure such that a portion of said at least one of a pig train and a sealant composition enters at least a part of said premises-side pipe network to a location of said leak to seal said leak.
A method for sealing a leak at a leakage site in a premise-side pipe, the method comprising:
- a. activating a pressure control system for controlling a pressure in said premises-side pipe network, the pressure control system comprising at least one flow meter configured to measure a liquid flow rate and at least one valve for controlling said pressure;
- and
- b. passing at least one gel pig and a sealant composition comprising fibers under pressure along a premises-side pipeline such that a portion of said at least one gel pig and said sealant composition enters said premises-side pipeline from outside said premises at said pressure;
- and
- c. allowing said portion to reach said leak site and to seal said leak.
