Well the thing is, they don't really know! modern plastic pipes have only been used in plumbing for around 20 years or so, so the total lifespan is unknown, apparently it is the rubber seals in the plastic piping that is likely to go rather than the pipe itself. I guess given most people change their bathroom every 20 years or less then it probably won't be an issue for most, as can just change the pipes at that point.
We have a mixture of copper and plastic in house, simply because I couldn't afford to do all copper, given the amount of pipes we have!

Lol.
Who here;
a) has lived in the same place for 20yrs, and / or
b) has a 20yo bathroom?Not having a pop btw as I know what you mean. Just sceptical (partially as we had a leaky copper pipe) whether properly installed plastic pipe is in reality any less reliable.

Is that true?
Over what sort of time period do the plastic fittings fail?
