Where Should You Not Use Pex?

1. PEX can’t be installed in high heat areas
2. You can’t install PEX in high heat areas like near recessed lighting
3. This also means you can’t connect PEX directly to a hot water heater, but you can use a connecting material to do this

subsequently, How close can PEX be to a water heater? The Uniform Plumbing Code (UPC 60413) states that “PEX tubing shall not be installed within the first 18 inches of piping connected to a water heater” But the UPC is not used in all jurisdictions

Do plumbers like PEX?

Then, Should I replace my copper pipes with PEX? Coupled with low production and shipping costs, the savings resulting from installing PEX instead of copper pipes can be significant Better Energy Efficiency – PEX has a lower thermal conductivity rate than copper As a result, PEX pipes can help keep hot water hotter for longer periods of time

What are the disadvantages of using PEX pipe? The biggest disadvantage to PEX is that it is unknown how well or long it will last While PEX piping is warrantied for up to 25 years, it is unknown what could happen to PEX piping as the years go on Since it is so new, it is hard to know what water will do to the plastic over 30 years
