Maintaining Copper Piping: Cleaning Old Pipes in the Basement Safely and Effectively
When it comes to the old copper piping in the basement, many homeowners wonder if it's necessary to clean these systems. After all, the visible corrosion on the surface of the pipe may appear superficial, but ignoring it can lead to serious issues down the line. This article will guide you through the best practices and methods for safely and effectively addressing these pipes without causing further damage.
Understanding Copper Piping and Corrosion
Copper piping has been a popular choice for household plumbing for decades due to its durability and resistance to rust and corrosion. Copper is a naturally antimicrobial metal and is highly resistant to most common household chemicals and waterborne contaminants. This means that while you may see some surface corrosion, it is unlikely to affect the internal structure of the pipe.
Corrosion, in the context of copper piping, is typically superficial and does not penetrate deeply into the metal. This is why it is often referred to as surface corrosion. Some homeowners feel compelled to clean the pipes, but it's important to understand that removing this superficial corrosion can actually expose underlying copper that is more susceptible to corrosion.
The Risks of Cleaning Copper Piping
Attempting to clean copper piping can be counterproductive and potentially dangerous. Here’s why:
Accelerated Corrosion
When you remove the protective layer of patina (the natural, built-up layer of corrosion), you expose the underlying copper to the elements. This can lead to accelerated corrosion in the affected area, potentially causing leaks or weak spots in the piping system.
Health Hazards
The cleaning process may involve harsh chemicals that can pose health risks if not handled correctly. Exposure to these chemicals can cause skin irritations, respiratory issues, or other health problems.
Environmental Impact
Improper disposal of cleaning chemicals can harm the environment. This is particularly problematic if the chemicals end up in drains or groundwater, affecting local ecosystems.
Warranty Issues
Most building codes and warranties specifically state that the homeowner is responsible for maintaining the basement and plumbing systems. Improper cleaning could void warranties and lead to costly repairs.
Safeguarding Your Piping
Given the risks involved, the best course of action is to avoid cleaning your copper pipes unless there is a specific issue or if a professional suggests it. Here are a few steps you can take to safeguard your piping:
Inspections
Regularly inspect your basement for leaks or signs of significant corrosion. If you notice any issues, consult a professional plumber who specializes in copper piping.
Protective Coatings
Apply a protective coating or sealant to the exterior of the pipes to slow down corrosion.
Proper Maintenance Practices
Avoid excessive pressure or overheating, which can stress the pipes and lead to premature failure.
Professional Maintenance and Repair
If you do find it necessary to clean copper piping, it's crucial to engage a professional plumber who is aware of the risks involved and knows the proper cleaning techniques. Here are some key points to consider during a professional maintenance session:
Proper Equipment
Ensure that the plumber uses appropriate equipment and techniques to minimize damage and environmental impact.
Chemical Use
Only use specialized cleaning products designed for copper and follow all safety guidelines.
Monitoring
Monitor the condition of the pipes post-cleaning to ensure that there are no new signs of corrosion or damage.
Conclusion
While the visible surface corrosion on copper piping in the basement may be concerning, it is usually not a cause for alarm. Regular inspections and proper maintenance practices are the best safeguards against serious issues. If you do find that cleaning is necessary, always consult a professional to ensure the process is handled safely and effectively. Ignoring the problem or attempting to clean it yourself can lead to potential hazards and costly repairs.
