What is wrong with PEX plumbing?

PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible to oxidative degradation.

Can I use PEX in my whole house?

This type of PEX is the most flexible of the three types and is suitable for use in all home water-supply plumbing needs. It expands to the greatest degree when subjected to freezing water, so it’s the most resistant to cracking in frigid temperatures. It’s easy to work with but it’s more expensive than B or C.

What is the life expectancy of PEX plumbing?

30 to 50 years





While you can expect PEX to last for 30 to 50 years, copper piping will outdo it by about two decades, with a typical lifespan of 50 to 70 years. Copper is a more durable option that isn’t susceptible to rodents or sunlight. These pipes can easily handle water pressure of up to 1,000 psi.

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.

Will PEX freeze and burst?

PEX pipes, just like any pipe, can freeze when the temperature drops too low. Because the pipes are designed to be flexible, PEX has the ability to expand. Although it is still possible for them to burst, this means PEX pipes are less likely to rupture after freezing.

Is it cheaper to run PEX or copper?

Copper Cost. PEX pipe costs significantly less than copper pipe. For example, 1/2-inch SharkBite PEX tubing costs about one-third the price of copper.

This is particularly important in cold regions, crawl spaces, attics, or other cold places. Doing so can also improve energy efficiency and reduce moisture and condensation.

How do you winterize PEX?

Ways to Keep PEX Pipe from Freezing

  1. Keep the room temperature above 55 F.
  2. Add insulation to particularly cold places such as attics, garages and basements.
  3. Drip faucets to keep water moving in the pipes.
  4. Shut off the water to outside hose bibbs (spigots) & drain the pipes.
  5. Install frost-free sillcocks.

Are SharkBite fittings freeze proof?

SharkBite repair couplings, tees, adapters, ball valves and pressure regulating valves allow you to make quick repairs to Copper or CPVC pipe and help to prevent future freezing. Simply remove up to two inches of damaged pipe, and repair with a single fitting, without using additional pipe.

What is better PEX crimp or SharkBite?



For situations where you are looking to implement a temporary fix, Sharkbite is the better choice. Sharkbite is also great in situations where crimping is not possible due to tight spaces.
