Contractors
often install pipes, water-based heat transfer systems, sprinkler
systems, and drain lines components made of chlorinated polyvinyl
chloride (CPVC) because they're less expensive, and easier, to work with
than those made of metal. These pipes and fittings can cause serious -
and costly - damage when they leak or burst.
CPVC components can fail for a variety of reasons. Because this
material is a thermoplastic made by combining raw materials, one or more
ingredients might be faulty. Errors in manufacturing can lead to
defects in the extrusion or injection-mold processes. Other potential
risks include inadequate warnings, and improper shipping and handling.
To minimize your exposure to losses when working with products made
of CPVC, construction risk management professionals recommend that you:
- Use proper handling and storage procedures - for example, avoid exposing CPVC components to sunlight.
- Make sure that the booster pump pressure is not too high when designing the piping system.
- Do not use CPVC components in pressurized-air applications.
- Review assembly techniques carefully.
- Check the type of adhesive used, and the amount (the Goldilocks principle).
- Set the right amount of dry time.
- Inspect the alignment of pipes and fittings.
Last, but not least, do not mix CPVC pipes and fittings with those
made from its distant cousin, polyvinyl chloride (PVC), which has
different chemical properties, physical characteristics, and
capabilities.
Of course, most of these precautions apply just as well to installing pipes or fittings made of any material.
