Common Drainage Problems and Solutions in Older New Zealand Properties

Older New Zealand properties often face unique drainage challenges that require specialised solutions. Recognising these issues and implementing appropriate fixes is crucial for maintaining the functionality and integrity of these properties. 

Legacy Drainage Systems: Understanding the Basics

What works for modern plumbing may not be suitable for those with older setups. Many older New Zealand properties have drainage systems that differ from current standards. These often include cast iron or terracotta pipes, which deteriorate over time.

The design of these systems may also fail to meet current water usage needs. Some older properties still combine stormwater and sewage in a single system. Recognizing these features is the first step in addressing drainage problems and implementing effective solutions with the help of professionals.

Common Drainage Problems for Older Properties

Root Intrusion

Tree roots seeking water can damage pipes, especially in older, fragile systems. Watch out for recurring blockages, slow drains, and gurgling sounds from pipes. This is one of the most persistent causes of drainage issues in older properties in New Zealand.

Pipe Deterioration

Older pipes can corrode, crack, or collapse over time, leading to leaks, water damage, soil erosion around foundations, and foul odours. Pipe deterioration should be addressed quickly to prevent extensive damage.

Inadequate Capacity

As properties are renovated or expanded, original drainage systems may struggle with increased water usage, resulting in frequent backups, slow draining fixtures, and overflowing during heavy rain. 

Effective Drainage Solutions

Non-Invasive Repairs

Modern technology allows for many repairs without extensive digging. Pipe relining and trenchless pipe replacement can address drainage problems while preserving the property’s character and minimising disruption.

System Upgrades

In some cases, partial or complete system upgrades are necessary to solve drainage problems. This might involve separating combined systems, installing larger capacity pipes, or adding drainage points. A professional assessment can determine the most appropriate upgrades for your property’s specific needs.

Preventative Maintenance

Regular maintenance, such as annual professional inspections, periodic cleaning, and targeted root treatments, is vital for older drainage systems. This proactive approach extends the life of the system and prevents many common problems before they start.
