The maximum recommended operating temperature for PVC pressure pipe is 140°F. PVC pipe and conduit becomes stiffer with decreasing temperature and more flexible with increasing temperature. As with dimensions and pressure capacity, published pipe stiffness figures are applicable only for 73°F operating temperatures.
The main drawback to PVC pipe is the fact that it cannot be used with hot water applications. When exposed to hot water, PVC will warp. This means it cannot be used to deliver hot water to sinks, tubs and washing machines.
Beside this, Which plastic pipe is best for hot water?
CPVC
Likewise, Can I pour boiling water down PVC pipes?
Do NOT pour boiling water down your sink or toilet. This can melt PVC piping and pipe seals, causing serious damage. … However, this likely won’t accomplish much with more severe clogs, as all the fizzing reaction does is shift around whatever is clogging the pipe.
Also, How hot can PVC pipe handle?
140°F
Can PVC catch on fire?
Smoke and Vapors If PVC pipe does become hot enough to catch fire, it releases dioxins into the air, which are harmful to both humans and the environment. Additionally, once PVC does catch fire, it will produce more smoke than many other building materials.

How can heated water damage a pipe?
When hard water is heated, a certain amount of water evaporates, causing the minerals suspended in it to precipitate. … While copper, PVC and PEX pipes are more resistant to hard water buildup and corrosion, they can still get clogged or completely blocked by scale deposits.
Is uPVC good for hot water?
The short answer: No. Explanation: PVC is a thermoplastic, and therefore, at some point it will begin to degrade and break down as it’s heated up. It just so happens that Schedule 40 PVC’s maximum operating temperature is 140 degrees Fahrenheit, around the same temperature that hot water gets to in most homes.
