Polypropylene is Recyclable! PP is categorized as “Level 5” within the plastics recycle symbols standard. Where accepted, this plastic can be dropped into blue boxes and processed for re-use.
According to the Canadian Plastics Industry Association (CPIA), Canadians recycled almost 600 million pounds of plastic in 2011.
Over time, scale build-up in boilers and water heaters can cause heat exchangers to lose transfer efficiency. Plugged air filters can cause short-cycling in furnaces leading to over-heating. Problems like these can cause flue gas temperatures to climb beyond the capabilities of the venting material! These facts should be considered carefully when selecting a venting system.
There is more to installing PVC and CPVC pipe than cutting & gluing the pieces together. There is a long list of steps that should be followed while installing solvent welded pipe.
Common pitfalls that lead to problems with solvent welded pipe?
- Failure to properly cut, debur, chamfer, and clean pipe according to manufacturer’s instructions.
- Not using primer, or using the wrong primer/cement
- Using primer/cement that is too hot or too cold
- Using primer/cement on pipe that is too hot or too cold
- Application of too much or too little primer/cement
- Failure to hold pieces together until they have set
- Failing to follow directions as to curing time (24-48HR)
- Failure to follow pipe support instructions
UV Protection Is Required
Like all plastics, polypropylene can be damaged if exposed to direct sunlight for extended periods. To prevent degradation, installers should always use Black UV treated PP pipe when terminating.
