Many older homes in Eugene, OR, have a timeless appeal because of their craftsmanship and architectural character. However, behind the walls, the plumbing systems often tell a different story. Outdated designs, materials, and modifications made over decades can lead to violations of modern plumbing codes. These issues can affect safety, efficiency, and water quality. Addressing code violations early protects your investment and helps prevent expensive emergency repairs.
Outdated Piping Materials
Older homes may have plumbing that was considered safe when installed but no longer meets current standards. Pipe material is one of the most common areas of concern. Identifying what kind of piping your home has will help determine whether an upgrade is needed to keep your plumbing safe and efficient.
Galvanized Steel Pipes
Many homes built before the 1970s used galvanized steel pipes. These pipes were durable but tend to corrode from the inside. As rust and minerals build up, water flow slows, resulting in weak pressure at faucets and showers. Over time, corrosion can also cause pinhole leaks that start small but expand and lead to significant water damage.
Corrosion can also affect water quality by leaving a metallic taste or discoloration in the water. In some cases, heavy metals such as lead and cadmium can leach into your water supply. Modern plumbing codes recommend using corrosion-resistant materials such as copper, PEX, or CPVC, which provide cleaner water and more consistent flow. If your home still contains galvanized steel pipes, contact our team for an inspection. We can determine whether partial replacement or a complete repiping is the best solution.
Polybutylene Pipes
Polybutylene pipes were common between the 1970s and 1990s because they were inexpensive and easy to install. However, this material deteriorates over time, especially when exposed to chlorine in municipal water. Cracks and leaks can develop suddenly, leading to costly water damage. Because of these risks, polybutylene is no longer approved by plumbing codes.
Many homeowners do not realize they have this type of piping until a problem occurs. Replacing polybutylene pipes with modern materials brings your system up to code, improves water quality, and increases property value. It also gives you peace of mind knowing your plumbing system is safe and reliable.
Improper Pipe Sizing and Water Pressure
Older plumbing systems often use pipes that are smaller than what today’s codes require. Undersized pipes restrict water flow and cause pressure drops when multiple fixtures run at once. Low water pressure can strain appliances, reduce comfort, and make daily tasks such as showering or washing dishes more difficult. Ensuring proper pipe sizing and installing a pressure-regulating valve can make a significant difference in your home’s water performance.
Drainage and Venting Violations
Proper drainage and venting are essential for a functional plumbing system. Many older homes struggle in this area because the original designs predate modern code requirements. Understanding these issues can help prevent slow drains, foul odors, and more serious plumbing failures.
Incorrect Drain Slope
Drain pipes must maintain a specific slope for wastewater to flow freely. If the slope is too flat, water drains slowly and allows solids to settle, causing clogs. If it is too steep, water can move too quickly and leave debris behind. Older homes often have drainage lines installed at improper angles, leading to frequent backups and unpleasant odors. Modern codes establish precise slope standards to ensure smooth wastewater movement.
Insufficient Venting
Venting keeps air pressure balanced in the plumbing system and prevents sewer gases from entering your home. Many older systems lack proper venting or have vents that are too small. This can cause gurgling sounds, slow drainage, or dangerous air contamination. Modern codes specify the correct vent sizes and placement for optimal system performance and safety.
Fixture Placement and Clearance Violations
Plumbing codes outline minimum clearances around toilets, sinks, and tubs to ensure safety and accessibility. Many older homes have cramped bathroom layouts that violate these requirements. Inadequate spacing makes repairs difficult and increases the chance of injury. Updating fixture placement improves both safety and usability while ensuring your bathroom meets modern standards.
Water Heater Code Violations
Older water heaters may not comply with today’s safety codes. Common issues include insufficient clearance, missing seismic strapping, or inadequate ventilation for gas units. Electric water heaters may lack proper grounding. These violations can increase the risk of fire, leaks, and inefficiency. Replacing or updating your water heater ensures compliance and helps it operate safely and effectively.
Backflow and Cross-Connection Issues
Backflow prevention is critical to maintaining clean drinking water. Many older homes lack backflow prevention devices on outdoor faucets or auxiliary water lines. Without these devices, contaminated water can flow backward into the clean water supply. Modern plumbing codes now require backflow protection for nearly all non-potable water connections. Installing these devices protects your household and ensures safe, high-quality water.
Pipe Support and Insulation Deficiencies
Older plumbing systems often lack proper supports and insulation. Pipes that are not securely supported can sag and eventually leak. Missing insulation in unconditioned areas like crawl spaces can also lead to freezing during winter. Upgrading supports and insulating exposed pipes improves reliability and helps protect your home from water damage.
Water Pressure Regulation
Many older homes were built without pressure-reducing valves, which are now required by modern codes. Without regulation, high water pressure can strain pipes, fixtures, and appliances, increasing the risk of leaks or bursts. Installing a pressure-reducing valve stabilizes your water pressure and extends the life of your plumbing system.
Sewer Line Compliance
Old sewer lines are often made of materials that deteriorate over time, such as clay or cast iron. Cracked or misaligned pipes can cause blockages, backups, and even contamination. Modern plumbing codes specify durable materials and proper slope and depth for reliable performance. A professional camera inspection can identify issues and guide you toward repair or replacement before a major problem develops.
Shut-Off Valve Requirements
Many older homes have only a main water shut-off valve, which means turning off the entire water supply during repairs. Current plumbing codes require individual shut-off valves at every fixture. Installing these valves adds convenience and minimizes water waste by allowing localized repairs.
