I installed PPR pipes in my house for water supply and now after investing so much of money and time a person today told me that plastic pipes are not good enough as they burst in freezing temperatures( we live in freezing temperatures and normally it dips 5 degrees Celsius below zero in winters). And also said that if hot water from a geyser(a water boiler) passes through them then the water stinks of the plastic!
From listening to this I'm very anxious and depressed. Has the money been wasted? I've added a picture which has the details written on it, the right one is more detailed. Any help is appreciated. God bless you.
