Common Plumbing Problems in Older Homes and How to Solve Them

By June 17, 2024No Comments

Living in an older home is like owning a piece of history, each corner rich with stories from the past. Yet, the beauty of these aged structures often comes with the challenge of maintaining old infrastructure, particularly the plumbing systems. These essential yet usually outdated systems present unique technical challenges that require more than simple repairs; they demand a deep understanding and a proactive approach to ensure longevity and functionality.

Looking into the plumbing of older homes is not just about fixing immediate problems—it’s about preserving historical integrity while updating essential services to meet modern standards. In this blog post, we’ll discuss eight common plumbing issues that owners of older homes frequently encounter, examine their various aspects, and provide sophisticated solutions.

Outdated Pipe Materials

Challenge: Many older homes still rely on plumbing made from galvanized steel, lead, or polybutylene. Over time, these materials can degrade through processes like corrosion, leaching, and becoming brittle, which ultimately weakens the plumbing system’s overall integrity.

Solution: The remediation strategy involves systematically replacing these obsolete materials with contemporary alternatives like copper or PEX (cross-linked polyethylene). This process necessitates a detailed assessment of the existing pipeline layout, followed by a phased removal and installation strategy. The new installation should prioritize minimal structural disruption and adherence to current plumbing needs.

Poor Water Pressure

Challenge: Reduced water pressure in older homes can often be attributed to internal pipe corrosion and sediment accumulation, which diminish the internal diameter of the pipes and impede water flow. 

Solution: A systematic evaluation of the plumbing network is essential to identify severely deteriorated sections. Remedial action may involve localized replacement or, where sedimentation is extensive, hydraulic flushing to restore diameter and flow capacity. This approach ensures that pressure is normalized without a complete system overhaul, preserving structural and historical integrity.

Sewer Line Degradation

Challenge: Traditional sewer lines made from clay or cast iron are susceptible to environmental stresses such as root intrusion and soil shifts, leading to fractures and blockages.

Solution: Video camera inspection allows for precise identification of problem areas within the sewer system. Mechanical root cutting followed by trenchless repair techniques, such as slip lining or pipe bursting, can restore sewer line functionality with minimal disruption to the surrounding environment.

Inefficient Water Fixtures

Challenge: Fixtures in older homes are typically not designed for water efficiency, leading to higher consumption and increased utility expenditures. 

Solution: A practical step is to swap out old fixtures for modern, low-flow ones that meet EPA WaterSense standards. It’s key to ensure these new fixtures will fit with your existing plumbing to prevent the need for major changes. This update reduces water usage and works smoothly with your home’s plumbing, helping with issues like leaky faucets and toilets. 

Drainage Issues

Challenge: Narrow or obstructed drainage pipes, common in older homes, lead to slow drainage and frequent backups.

Solution: Mechanical snaking is effective for immediate clog removal. For comprehensive maintenance, hydrojetting should be considered to address tougher sediment buildup. Establishing a regular cleaning schedule using environmentally friendly agents like baking soda and vinegar can prevent severe blockages and maintain optimal flow.

Leaky Faucets and Toilets

Challenge: Aging fixtures in older homes frequently develop leaks due to worn-out internal components such as washers, gaskets, and valves.

Solution: Technical refurbishment of these fixtures involves disassembly, replacement of defective components, and careful reassembly to ensure a tight, leak-free seal. Using high-quality replacement parts is essential for extending the lifespan of the fixtures and reducing future maintenance needs.

Inadequate Venting

Challenge: Older plumbing systems often suffer from inadequate venting, which can lead to slow drainage and the emission of sewer gases into the home.

Solution: Assess and upgrade the venting system to meet current building codes. This may involve adding additional vents or replacing clogged or improperly sized vents to ensure proper airflow and prevent pressure issues that disrupt drainage.

Thermal Expansion Complications

Challenge: Just like our joints can become stressed and strained without proper support, traditional plumbing systems in older homes often struggle under pressure. These older systems typically lack the modern mechanisms that manage the expansion of water as it heats up. Without this, as the water expands, the pressure builds up inside the pipes and fixtures, which can stress them to the breaking point, leading to leaks.

Solution: The remediation involves integrating a thermal expansion tank into the existing water heating setup. This tank serves as a cushion, absorbing excess pressure caused by the heated water and thereby maintaining a balanced pressure throughout the plumbing system. Installation should be strategic, with placement near the water heater to optimize pressure relief and ensure system longevity. This approach not only eases the strain on pipes and joints but also helps keep the water heating system working reliably.
