The rest of the house was warm enough that the pipes wouldn't freeze.
With wrought iron pipes bends may be arranged, as shown in fig.
The pipes are best supported on rollers which allow of movement without straining the joints.
The pipes have specially shaped ends between which a rubber collar is placed, the joint being held together by clips.
One end of each pipe is plain, so that it may be cut to any desired length; pipes with shaped ends obviously must be obtained in the exact lengths required.
