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.enter image description here

    How close to a geyser do you live that there's a possibility of one erupting through your plumbing? On a more serious note, if you don't smell the plastic when you run hot water now, it's not likely that you will in the future. Also, congrats on including a nice, clear, readable pic in your OP without having to be prompted! It's amazing how many people don't do that...

    @EdBeal The OP & the pic clearly show PPR on the pipe, but you mention PPE. Are those different pipe types or was that a typo on your part?

    What does a geyser have do to with this? I'm guessing this is a translation error. In the US, a geyser is a geological structure that regularly erupts hot water (like Old Faithful at Yellowstone NP). Jun 24 '20 at 14:06

    @George Anderson, I meant a water boiler by geyser, I've edited the question. Thank you for pointing it out

I'd insulate the pipes and move on

PPR, like PEX and unlike PVC, is a freeze-tolerant material; however, that doesn't mean that pipes made from it should be allowed to freeze on a routine basis. I would start by adding pipe insulation (foam pipe insulation is available as prefab, "peel and stick" pieces) provided these are not irrigation pipes, which should be drained/blown out for the winter season anyway. I am baffled as to how you wound up with plumbing runs on the outside of your house, though...
