Fixing brittle CPVC pipes may involve replacing the damaged or faulty components. Hiring a professional plumber is crucial as they possess the necessary expertise to efficiently address issues and avoid potential difficulties.

PVC vs. CPVC Pipes

What is the Difference between PVC and CPVC Pipes?

PVC pipes are made of unplasticized polyvinyl chloride, while CPVC pipes are made of chlorinated polyvinyl chloride. The main difference between the two types of pipes is the presence of chlorine in CPVC pipes, which makes them more durable and resistant to chemicals.

Can you Replace PVC Pipes with CPVC Pipes?

Yes, in some cases, you can replace PVC pipes with CPVC pipes. However, this requires careful consideration of the compatibility of the pipes and fittings and possible changes in the flow rate and pressure.

What are the Pros and Cons of Using PVC and CPVC Pipes?

PVC pipes are cheaper and widely available, while CPVC pipes are more durable and chemical-resistant. However, CPVC pipes can be more expensive and require careful installation and maintenance to avoid issues.

Corrosion and CPVC Pipes
