Are plastic pipes as good as copper?

John Conlin / 21 March 2017

Chartered surveyor John Conlin explains why plastic pipes can be better than copper pipes.



Question

We are house hunting and have seen a house that we like. It is new and about half finished. 

The plumbing, including the central heating is all in plastic piping. 

Is this just a cheap alternative to proper copper pipes, and will it last as long?

Answer

Plastic piping is not significantly cheaper than copper; however the cost savings come from faster installation times as the pipes can be easily bent and the fittings are of a simple ‘push-fit’ type.

 As to their length of working life I think that one can assume at least 100 years on the basis that the water companies are using them to replace main supply pipes.
