The PPR pipe is extruded from type III polypropylene. The pipe itself has flexibility. The temperature is below 5 degrees Celsius. The PPR pipe will undergo molecular changes, and the pipe’s own flexibility will decrease and the rigidity will increase. This is specifically manifested in the situation of excessive external pressure. There will be the possibility of rupture, which is also a normal physical phenomenon and cannot be avoided.
PPR water pipe antifreeze tips:
Before going to bed, close the doors and windows of the kitchen, bathroom and other rooms with faucets and pipes, so that the indoor temperature is not too low.
It is recommended to vent the external water facilities such as solar energy. Similarly, the pipes in the home can also be vented to prevent freezing. When the temperature is below -5°C, it is best to close the main domestic water valve when not using water, open the faucet, and drain the remaining water in the water pipe to prevent the pipes and water appliances from freezing.
Conditional users can let the faucet continue to discharge water in a small flow, and the discharged water can be collected in a bucket and recycled.
When the pipes and faucets are frozen, do not twist them hard or start them with pliers or other tools, let alone roast them with fire or pour them directly with boiling water. The correct way is to wrap the faucet with towels and other things, and then pour warm water along the faucet to the water pipe to defrost it. Indoor pipe freezing can increase the room temperature to thaw.
It is best to reserve some emergency water at home, so that there is no water available after freezing.
PPR pipes are strictly prohibited to be thrown, dropped, rolled, or dragged during transportation.
Understand these tips, prepare before the cold winter, and deal with all kinds of water pipe problems freely, so that your water pipes will be more frost-resistant.
