Pre-Purchase Drain Inspections Auckland
Before you buy, make sure you know exactly what you’re getting.
Hydro Vision’s pre-purchase drain inspection service reveals the true condition of a property’s drainage system, helping Auckland home buyers avoid expensive surprises after settlement.
Using advanced CCTV camera technology, we uncover hidden issues that standard building inspections often miss — from cracked pipes and root intrusion to poor installation or design. You’ll receive clear video footage, an easy-to-read report, and honest advice so you can make confident property decisions.

Why You Need a Drain Inspection Before Buying
A building inspection only covers what can be seen above ground. Underground drainage issues are often ignored — and they’re the ones that cost the most to fix.
Common problems missed by building inspectors:
- Cracked or collapsed underground pipes
- Tree roots entering through joints or fractures
- Poor gradients or non-compliant installation
- Blocked or undersized stormwater systems
- Leaks that lead to foundation moisture or flooding
A professional pre-purchase drain inspection fills this gap, showing you the real condition of your new property’s drains before you sign.
What Our Pre-Purchase Inspection Includes
Full CCTV Drain Survey
We use high-definition drain cameras to inspect every accessible line — sewer, stormwater, gully connections, and internal plumbing. Our flexible systems navigate bends and joints for full coverage.
If needed, we can also inspect cesspits, soak holes, and fresh water lines using dedicated camera equipment.
Condition and Compliance Report
Our inspection reveals pipe condition, material types, flow direction, and system layout. You’ll know whether the drainage is adequate, compliant, and suitable for planned renovations.
Identification of Hidden Problems
We identify cracked or collapsed pipes, poor joins, tree root activity, or ground movement damage — the types of faults that lead to costly repairs later.
Tree Root Assessment
In Auckland’s mature suburbs, tree roots are a frequent culprit. Our inspection detects both active intrusion and risk factors for future damage.
Honest Recommendations
We’ll tell you what’s urgent, what can wait, and what’s typical for the property age and area — in plain English, not technical jargon.
The Hydro Vision Process
- Scheduling and Coordination – We work around real estate agents, vendors, and your settlement deadlines to make sure inspections happen quickly and smoothly.
