Know more about the drains before you buy.
The house may look right from the street while its drainage remains out of sight. Drain Kings offers pre-purchase sewer and stormwater inspections for buyers in Palmerston North and Manawatū, helping you ask better questions about the accessible drains before making a property decision.
- You are buying a house with unknown drain history
- The property has experienced recurring blockages
- You want accessible sewer and stormwater lines checked
- Drainage information is missing from your other inspections
- Your adviser has specific drainage questions

A focused check beneath the property
A drainage inspection adds information about an area a general viewing cannot show. A CCTV camera can examine accessible sections of pipework for visible obstructions, roots and condition issues. The purpose is to understand what can be seen, not to promise that every part of the system is defect-free.
Drainage is one part of your due diligence. Combine the findings with your building inspection, property information and advice from the professionals supporting your purchase. Do not assume a general building inspection includes an internal camera inspection of the drains.
Agree the scope before the visit
Tell Drain Kings the property address, purchase deadline and which drainage systems you want inspected. If your adviser needs particular information, footage or written findings, discuss that requirement before booking so the available service and outputs are clear.
The vendor or agent will need to authorise access. Drain plans, known access points and any previous drainage records are useful starting information. Where a line cannot be accessed or the camera cannot proceed, that limitation should be understood when considering the findings.
What may affect the inspection
Bends, blockages, standing water and debris can prevent a full view. Some sections may be inaccessible from the available entry points. Clearing may be needed before a useful inspection can continue, and that should be discussed rather than assumed.
A camera sees the interior surfaces visible during the visit. It does not expose every buried component, test all future performance or establish the full condition of a septic or treatment system. Ask the team what the proposed inspection covers for that property.
Turn findings into useful questions
If an issue is found, ask where it was observed, what part of the line was inspected and what further assessment might be needed. Keep the distinction between an observation and a confirmed diagnosis clear.
Allow time to review the information before any relevant purchase deadline. Contact Drain Kings early to discuss scheduling; availability and the property’s access arrangements will influence when an inspection can take place.

Common questions
Pre-Purchase Drain Inspections — common questions
Does this replace a building inspection?
No. It is a focused drainage inspection that can complement other due diligence. Confirm the scope of each inspection with the provider.
Can you inspect before an offer becomes unconditional?
Discuss your deadline as early as possible. Scheduling depends on availability, vendor permission and access. No particular completion time is guaranteed.
Will every pipe be inspected?
Not necessarily. Access, pipe layout, obstructions and visibility determine what can be reached. Agree the intended scope and ask about any sections that could not be inspected.
