What Questions Should I Ask a Drain Cleaner About Their Experience and Equipment?

Hiring the right drain cleaner in NZ means asking the right questions. Here's what to check before you book.

What Questions Should I Ask a Drain Cleaner About Their Experience and Equipment?

Choosing a drain cleaner in New Zealand isn't just about finding the cheapest quote — it's about making sure the person you hire has the right qualifications, tools, and experience to fix your problem properly the first time. Asking a few targeted questions upfront can save you a lot of money, stress, and repeat call-outs down the track.

Are They Licensed for Drainlaying Work?

This is the most important question to ask. In New Zealand, drainlaying is restricted work under the Plumbers, Gasfitters, and Drainlayers Act 2006. Anyone who carries out, supervises, or inspects drainlaying work must be registered and licensed with the Plumbers Gasfitters & Drainlayers Board (PGDB).

Unlicensed drain work is illegal and can void your home insurance, create liability issues, and lead to costly repairs if something goes wrong. Always ask:

  • "Are you a licensed drainlayer?" — Ask for their licence number and verify it on the PGDB website.
  • "Is your licence current?" — Licences must be renewed annually.
  • "Will you provide a Certificate of Compliance?" — For any restricted drainlaying work, a licensed tradesperson must issue this document.

Note that basic drain clearing (unblocking a drain without altering pipework) may not always require a drainlaying licence, but any repair, replacement, or new connection to the drainage system does. If you're unsure, check with your local council or the PGDB.

How Much Experience Do They Have?

Experience matters enormously in drain work, where problems can range from a simple blockage to a collapsed pipe or tree root intrusion. Good questions to ask include:

  • "How long have you been working as a drain cleaner or drainlayer?"
  • "Have you worked on properties similar to mine?" — Older NZ homes may have clay or concrete pipes; newer builds typically use PVC. Each has different challenges.
  • "Are you familiar with local council drainage requirements?" — Requirements can vary between councils, so local knowledge is valuable.
  • "Do you have experience with both residential and stormwater drainage?" — In NZ, the NZ Building Code covers both sanitary (G13) and stormwater (E1) drainage systems, and they are treated differently.

What Equipment Do They Use?

The right equipment makes a big difference to how thoroughly and safely a job is done. Ask:

  • "Do you have a CCTV drain camera?" — A camera inspection is the gold standard for diagnosing blockages, cracks, root intrusion, or pipe collapse. Without it, a tradesperson is essentially guessing.
  • "Do you use a high-pressure water jetter?" — Hydro-jetting is far more effective than a simple drain snake for clearing grease, scale, and root build-up.
  • "Do you carry a drain snake (electric eel) as well?" — For some blockages, a mechanical snake is the right tool. A well-equipped operator will have both.
  • "Can you provide a written report with CCTV footage?" — This is useful for insurance claims, council compliance, or future reference.

What Does the Quote Include?

Transparency around pricing protects you from unexpected costs. Ask:

  • "Is the quote fixed-price or hourly?"
  • "Does it include a camera inspection, or is that extra?"
  • "What happens if you find a bigger problem once you start?"
  • "Are call-out fees included?"

As a broad guide, costs vary depending on the job, region, and complexity — always get at least two or three quotes rather than relying on any specific price range. Prices vary by region and complexity — always get at least two or three quotes.

Do They Carry Insurance?

Always ask:

  • "Do you have public liability insurance?" — This protects you if they accidentally damage your property.
  • "Are your workers covered by WorkSafe-compliant health and safety practices?" — Drain work can involve confined spaces and hazardous materials. Check WorkSafe NZ for what employers are required to provide.

Can They Provide References or Reviews?

A reputable drain cleaner should be happy to point you to:

  • Online reviews (Google, Trademe, or tradedirectory.co.nz)
  • References from previous customers
  • Examples of similar jobs they've completed

What Guarantees Do They Offer?

  • "Do you guarantee your work?" — Ask for the timeframe and what it covers.
  • "What's your process if the problem returns?"

When to Call a Professional

Always call a licensed drainlayer if you notice:

  • Multiple drains backing up at once — this suggests a main drain blockage or collapse
  • Sewage smell inside or outside your home
  • Wet patches or sinkholes in your yard — possible pipe failure underground
  • Slow drains that don't respond to basic clearing

For anything beyond pouring boiling water or a basic plunger, it's safest to bring in a professional. You can find qualified, local drain cleaners and drainlayers on tradedirectory.co.nz.

Frequently Asked Questions

Does a drain cleaner in NZ need to be licensed?+

It depends on the work. Basic drain unblocking may not require a licence, but any repair, replacement, or connection to the drainage system is restricted work under NZ law and must be carried out by a licensed drainlayer registered with the PGDB. Always check their licence number on the PGDB website before hiring.

What is a CCTV drain inspection and do I need one?+

A CCTV drain inspection uses a small waterproof camera fed through your pipes to identify blockages, cracks, root intrusion, or collapsed sections. It's the most reliable way to diagnose a drainage problem and is strongly recommended before any significant repair work, so you know exactly what you're dealing with.

How do I verify a drain cleaner's licence in New Zealand?+

You can verify a drainlayer's licence on the Plumbers Gasfitters & Drainlayers Board (PGDB) website at pgdb.co.nz. Simply search by name or licence number to confirm their registration is current and covers the type of work you need done.

What's the difference between a drain snake and a water jetter?+

A drain snake (or electric eel) is a mechanical cable that physically breaks up or hooks blockages. A high-pressure water jetter uses a powerful stream of water to blast away grease, scale, and roots. Jetters are generally more thorough for stubborn blockages, but a good operator will carry both tools and choose the right one for your situation.

Should I get multiple quotes for drain cleaning work?+

Yes, it's always a good idea to get two or three quotes, especially for larger jobs involving repairs or pipe replacement. Make sure each quote clearly outlines what's included — such as camera inspection, jetting, and any follow-up work — so you're comparing like for like.
