Shut off the water supply at the base of the toilet by turning the shut-off valve clockwise.

There should be a shut-off valve in each of the two pipes under the sink.

Individual shut-off valves should be installed at each drop pipe to isolate it from the rest of the system for maintenance.

Emergency workers had to clamber across a ladder above the rushing water to get to the shut-off valves.

"We have to turn the shut-off valve, take the pipe apart, put on a new connector, and stick it back together again."

Next, prepare to solder the shut-off valves to the ends of the pipes.

Polish an area about a half-inch wider than will be covered by the shut-off valve when it is in place.

The team finally reached the shut-off valve about five miles from the explosion.

Open the shut-off valves, fill the sink with water and allow it to drain.
