Insights Into The Water Lines

Unable to make up your mind between copper and plastic for the water line of your fridge? Then there is a good chance that you would find this article useful. Down below is a summary of everything that you should know about both materials.

Copper And Plastic: Overviews 

  • Copper: Versatile and flexible, water lines that incorporate copper give a good account of themselves in various settings. Moreover, unlike their contemporaries on the market, copper water lines never leave odd tastes in the water which is a big plus. It’s worth pointing out that copper resists corrosion well so there is no need to worry too much about rust. That being said, since copper water lines tend to kink in use, water blockages occur from time to time.
  • Plastic: Available at reasonable prices, water lines made from plastic suit the shopping budget of the average homeowners. However, plastic is not exactly a resilient material so plastic water lines could easily sustain damages and lead to water leakages. In addition, the fact that plastic may cause water to taste odd means quite a few people prefer to avoid plastic water lines. Last but not least, similar to their copper counterparts, plastic water lines get kinked every now and then.

A Comparison Of The Water Lines 


In terms of strength, everyone agrees that copper is the one that comes out on top in refrigerator water line copper vs. plastic. While rough use alone would destroy plastic water lines, copper ones should be able to handle a wide range of abuses with relative ease. As a result, the replacement interval of plastic water lines is shorter than that of their copper counterparts. Unsurprisingly, those who don’t have many chances to pick up new water lines hold copper in high esteem.


It’s not difficult to manipulate copper and plastic water lines but the flexibility of plastic ensures outstanding handling. Because of that, once it comes to installation, plastic water lines require less time and effort than copper ones. Nonetheless, the rigidity of copper provides stability so copper water lines rarely move out of place after the setup process concludes. With copper water lines, there is no need to do much for a smooth flow of water.


Since water flows through copper water lines without changing in any way, homeowners don’t have to bother with effects. On the other hand, plastic water flowing through water lines before reaching the fridges often ends up with odd tastes.


Generally speaking, the price for water lines of refrigerators fluctuates on occasions but between copper and plastic, copper is the more expensive one. Therefore, regarding affordability, it’s safe to say plastic is the winner in refrigerator water line copper vs. plastic. By buying plastic water lines, homeowners could set aside a couple of bucks for other needs. Still, as mentioned above, plastic fails faster than copper so copper water lines allow people to save more money in the long run.

All in all, the characteristics of copper and plastic water lines for refrigerators allow them to excel in particular arrangements. To get your money’s worth, it’s strongly recommended that you spare a bit of time to check out these suggestions.

Hand tighten the water line in the beginning then use a wrench to tighten it for good.
