Description

When water freezes, it expands to a larger volume than it occupied in the liquid state. This expansion change can form ice plugs which exert several thousand pounds of pressure per square inch. This pressure could rupture a pipe wall if there is no place for the new volume to occupy.

When ICE-LOC® core is placed in a pipe, ICE-LOC® will occupy a known volume and compress, allowing the expansion of the ice to occupy the space needed. This will prevent rupture of the pipe, even if all the water freezes. The spongy core will return to it's initial working diameter. When the ice thaws, thereby having protected the pipe from rupturing. The water can now continue to flow with no damage to the pipe. ICE-LOC® is now ready to protect the pipe again.

The trunk is constructed of a proprietary resilient, flexible elastomeric sponge  material (FDA approved), that won't degrade in water, surrounding a tough, bendable reinforcing twine. The reinforcing twine prevents stretching of the core by the continued flow and pressure of water over the core length.

The reinforcing twine also serves a means for easy splicing of one core to another length of core. You can also tie the core to the trunk of another length of core at a tee junction, instead of using another compression clip or change core sizes when pipe run changes diameter of pipe.

Key Benefits:

• ICE-LOC® can be used in either new or existing plumbing.
• ICE-LOC® is usable with PVC Schedule 40 or better, Type L copper
  or better and steel pipes.
• ICE-LOC® poses no risk of contamination to water. The Elastomer
  is an FDA-approved material.
• ICE-LOC® does not require the use of specialty pipe or fittings.
• ICE-LOC® prevents water hammering.
• ICE-LOC® is a water-saving device.
