If you have Kitec plumbing in Sacramento, it might be worth replacing it with copper or PEX to avoid potential issues in the future.

Both copper and PEX have their advantages. Best of all, they are considered more reliable and safer than Kitec plumbing. 

Copper is very durable. With proper maintenance, it can last 50 years or more. It can also withstand high temperatures, making it suitable for both hot and cold water lines. Copper also has natural antimicrobial properties and doesn’t leach chemicals into the water supply, helping keep your water supply safer for your health.

On the other hand, PEX is a more flexible material for repiping, allowing for easier installation, especially in tight spaces. Fewer fittings can also mean fewer potential leak points compared to copper. 

In terms of cost, PEX piping is less expensive than copper in terms of both materials and installation labor.

Unfortunately, PEX is sensitive to UV light. UV rays can degrade the material, so they aren’t advisable in applications requiring prolonged exposure to sunlight. 

As a rule of thumb, copper is the better choice if you prioritize durability and are willing to invest more. But if you seek a cost-effective and flexible solution, PEX is the better option.
