- ABS
- Rubber Hose
- Dishwasher Hose
- Galvanized Pipes
The objective was to observe any changes or damage over a 60-day period after applying Coke to each pipe type.
4. Results and Observations
After 60 days of exposure to Coke, each pipe type was examined for signs of damage, corrosion, or any other changes.
a. PVC vs. Coke
PVC pipes showed minimal to no signs of damage. The chemical composition of PVC makes it highly resistant to acidic substances like Coke, maintaining its integrity throughout the experiment.
b. Steel Pipe vs. Coke
Steel pipes exhibited slight rusting and surface roughness, particularly around the threaded areas. While not severely damaged, the rust indicates that prolonged acid exposure can weaken steel pipes over time.
c. Dishwasher Hose vs. Coke
The dishwasher hose, typically made of rubber, remained largely unaffected. The flexibility and material composition of rubber hoses offer good resistance against acidic substances.
d. Rubber Hose vs. Coke
Similar to the dishwasher hose, standard rubber hoses showed no significant damage, maintaining their flexibility and functionality.
e. Schedule 10 PVC vs. Coke
Schedule 10 PVC pipes, known for their thinner walls, remained intact with no visible signs of wear or damage, underscoring PVC’s resilience to acidic exposure.
f. ABS Pipe vs. Coke
ABS pipes showed no noticeable damage. Like PVC, ABS is a plastic-based material with excellent resistance to acids, ensuring durability even under prolonged exposure.
g. Chrom-Plated Brass vs. Coke
Chrom-plated brass pipes displayed some discoloration and minor surface erosion. While the chrome plating provided a protective barrier, the underlying brass showed early signs of corrosion.
h. Copper vs. Coke
Copper pipes maintained their appearance with no significant pitting or surface damage. Copper’s natural resistance to corrosion makes it a durable choice, even when exposed to acidic substances.
i. Cast Iron vs. Coke
Cast iron pipes showed some surface rusting and minor cracks, particularly around joints and fittings. The acid in Coke can accelerate corrosion in cast iron over extended periods.
j. Galvanized vs. Coke
Galvanized pipes exhibited noticeable rust and corrosion, especially along the threaded connections. The zinc coating, while protective, began to degrade under acidic exposure, leading to increased vulnerability.
5. Analyzing the Impact of Coke on Pipes
The experiment reveals that the impact of Coke on plumbing pipes varies significantly based on the material:
- Highly Resistant Materials: PVC, ABS, and rubber hoses showed exceptional resistance to acidic exposure, remaining unaffected after 60 days.
- Moderately Resistant Materials: Copper pipes maintained their integrity, while chrom-plated brass showed minor surface erosion, indicating that these materials can withstand acidic substances but are not entirely immune.
- Less Resistant Materials: Steel, cast iron, and galvanized pipes exhibited signs of rust and corrosion, highlighting their vulnerability to prolonged acidic exposure.
6. Conclusion: Is Coke Bad for Your Plumbing?
Based on the experiment’s findings, Coke does have some detrimental effects on certain pipe materials, particularly those made of steel, cast iron, and galvanized coatings.
