Some water pipes are made from chlorinated polyvinyl chloride (CPVC) which has a higher chlorine content than standard polyvinyl chloride (PVC) pipes. This means CPVC can withstand a wider range of temperatures than standard PVC piping.
Electrical and network cable sheathes contain plasticisers to ensure the flexibility of the cables. These plasticisers are not compatible with CPVC and may cause degradation of the pipe. This could result in pipe failure.
