A rotted-out cast iron kitchen drain can be a major headache for homeowners, but the solution is simpler than you might think. By switching to ABS (Acrylonitrile Butadiene Styrene), you can avoid future plumbing issues and enjoy a more durable and efficient drainage system. In this blog, we will discuss the advantages of replacing a rotted-out 2″ cast iron kitchen drain with ABS and why making this switch is a smart move.

1. Corrosion Resistance

Unlike cast iron, which is prone to rust and corrosion over time, ABS is highly resistant to these issues. The use of ABS in kitchen drains ensures longevity and minimizes the risk of leaks and costly repairs.

2. Lightweight and Easy to Work With

ABS pipes and fittings are lightweight and easy to handle, making the installation process more straightforward. The reduced weight also puts less strain on the plumbing system, prolonging its lifespan.

3. Smooth Interior Surface

ABS pipes have a smooth interior surface, which promotes better water flow and reduces the likelihood of clogs. The smooth surface also inhibits the accumulation of debris and grease, leading to improved drain performance.

4. Cost-Effective Solution

Switching to ABS for your kitchen drain replacement is a cost-effective solution in the long run. The durability and low maintenance requirements of ABS can save you from frequent repairs and replacements associated with cast iron.

5. Noise Reduction

ABS pipes offer excellent noise reduction properties, minimizing the noise produced by water flow and contributing to a quieter and more comfortable kitchen environment.

6. Environmentally Friendly

ABS is a recyclable material, making it an environmentally friendly choice for your plumbing system. By opting for ABS, you are making a sustainable choice that aligns with eco-friendly practices.

7. Resistant to Chemicals

ABS pipes are resistant to many chemicals commonly found in household cleaning products, ensuring that your plumbing system remains intact and efficient.


Replacing a rotted-out 2″ cast iron kitchen drain with ABS offers numerous benefits that improve the overall functionality and longevity of your plumbing system. From corrosion resistance and smooth water flow to cost-effectiveness and environmental friendliness, ABS proves to be a smart and practical choice for any homeowner. Make the switch to ABS and bid farewell to plumbing woes, knowing you have invested in a durable and reliable kitchen drainage solution.
