Each has their own use and both have their champions. That being said, we should all make our own decision on the matter. We presented all the facts and figures in the debate between the two choices and even asked our branch managers for their opinions on the matter. For example, Kevan Rimmer of City Plumbing in Ramsey stated “they are best used for different situations depending on their usage”.
Plastic Plumbing
The new kid on the block, PVC (polyvinyl chloride) has only really been around for the last 60 years. In that time, the creation of PVC has evolved to create a strong, lightweight and durable compound that is now used in a lot of new homes, becoming the go-to material for DIY plumbing at the same time.
Initially being invented in pre-war Germany, PVC plastic was installed in over 400 residences for drinking water and waste pipelines. Various test pipelines of PVC were laid in Leipzig, Dresden, Magdeburg, Berlin, Hamburg, Cologne, Heidelberg and Wiesbaden, most of which is still being used today. The longevity and durability of the new form of water transportation was enticing to business owners of the 50s and 60s who wished to find a cheaper alternative to copper piping.
Of course, plastic plumbing his its own number of pros and cons:
- Quieter, even at high pressure and water speeds
- Resist corrosion and impact damage
- Easier to install compared to copper pipes
- Less expensive than copper
- Doesn’t freeze as easily
- Doesn’t require a naked flame to install
- Not as flexible at the joint
- Can’t fit into as tight a space as copper
When talking to our branch managers. Mark Whickham of City Plumbing in Oban and Bobby Wray of City Plumbing in Darlington both pointed out that that plastic plumbing can be chewed and ruined thanks to rodents like mice or rats.
Copper Piping
Most older homes already have copper piping systems installed in them. Copper has always been the perfect choice for water piping, it is a strong, flexible naturally occuring metal and easily moulded into long thin pipe work that can fit within tight spaces.
- Fits into tighter spaces
- More flexible at the joints so resists vibration damage
- Fully recyclable
- Can corrode if the water running through is acidic
- More difficult/takes longer to install
- More expensive than plastic plumbing
- Noisier, especially at high pressure
Which is Safer?
One point that was highlighted in both the copper piping and plastic pros and cons were the health concerns that follow plastic plumbing. This stems from fears about the leaching of chemicals that can give water a plastic taste. That being said, the plastic taste tends to disappear after a few months of using. Thankfully there is no health risk directly linked to plastic pipes and any potentially health risks come from systems installed before 1977, as highlighted in a study printed in the ‘Journal of Environmental Engineering’.
Although copper piping is thought to be safe, the pipe can corrode if the water is acidic. Copper in large amounts has also been linked to certain health risks, such as Alzheimer’s in some cases. That being said, the body expels copper relatively quickly and small amounts of copper are perfectly safe. As such the risk of copper is minimal.
At the end of the day, health risks associated with these forms of piping are overblown and any health risk is largely non existent. The main source of contamination would be brown water potentially leaking into clean water pipes through cracks, or gaps in the joints.
Which Material is Better?
As stated by Kevan Rimmer of City Plumbing in Ramsey earlier, each material has its own use. For example, the improved corrosion resistance and impact damage resistance from PVC piping makes it more suitable for high-traffic areas. Whereas the smaller diameter you can get from copper piping makes them ideal for tighter spaces.
Mark Wickham of City Plumbing in Oban and Bobby Wray of City Plumbing in Darlington both have their own favourites. In their opinion the neater and more professional look you get from copper piping easily brings it out on top. There isn’t much difference in the performance of the two material types, so the only defining factors are the price and the appearance. There is no denying that plastic piping is the cheaper option, but if the choice is there, you can’t put a cost on a system that looks the part and will last a lifetime.
