Auckland Drainlayers: What Drainlayers Do

What Drainlayers Do

Drainlaying definition

The New Zealand Plumbers, Drainlayers and Gasfitters Association Inc. defines drainlaying as “any work involving the installation, alteration or repairs to a drain, including the fixing or unfixing of a drain to an onsite wastewater system (septic tank) or any trap.”

Drains are underground pipes installed for the purpose of carrying waste or surface water (stormwater) to either an onsite waste water disposal system (septic tank) or a sewer which is usually under the control of the local Council.

It’s vital that all drainage systems are properly installed and work to effectively remove all waste water thereby ensuring the protection of public health and maintaining a pollution-free environment.

What drainlayers do

Auckland drainlayers install and maintain the drains on residential and commercial properties throughout Auckland. This involves:

  1. Installation of new drainage systems.
  2. Repairs of existing drainage systems.
  3. Maintenance of drainage systems.
  4. Drainage inspections.

1] Installation of new drainage systems

New buildings (residential and commercial) and renovated buildings (when required) must have a drain system for both stormwater and waste. A certified Auckland drainlayer will know the relevant local building code that must be adhered to so that any drainlaying work is compliant to those regulations.

All drainlaying in Auckland and throughout New Zealand must comply with the local Council Building Codes. Whenever Building Consent is required, the drainlaying work must be checked by a building inspector from your local Council. A code compliance certificate cannot be issued until this is done.

2] Repairs of existing drainage systems

The most common malfunction of a drainage system is a blockage – often by plant roots but sometimes by a foreign object that has entered the system. Blockages can result in stormwater or sewerage backups and spillages which means it’s important to deal with them as soon as possible.

Septic tank systems can also overflow or backup when they reach capacity.

3] Maintenance of drainage systems

Once a blockage occurs in a drainage system it can cause significant damage and can be expensive to repair. For this reason, it’s a good thing to maintain rather than waiting until a repair is required. A drainlayer will check your existing drains, including septic tank systems, to ensure they are working at their optimal efficiency.

4] Drainage inspections

Drain blockages or leakages are not always easy to locate. Digging up the drain to locate the problem area is expensive. As Auckland drainlayers, we have access to the latest Closed Circuit Television (CCTV) camera technology. That means, with a CCTV drain inspection, we can quickly locate the cause of your drain blockage or leak and have things working 100% in no time.

A full drainage inspection is also required if you are undertaking drainage work in Auckland that requires Council consent.

Drainlayers service overview

The following is a list of services provided by most Auckland drainlayers:

  • Drain laying – for new and renovation-related drains.
  • Drain repair – for blocked, leaking and collapsed drains.
  • Drain surveying – for renovations or new drain systems.

  • Drain inspection and maintenance.

Can I do my own drainlaying?

If you are not registered as a drainlayer, you are not permitted to undertake any drainlaying work. You are permitted to clear blocked drains, but only if the task does not involve altering or repairing the inspection pipes or ventilation pipes in any way.

A drain blockage is the most common issue relating to drains. Clearing such a blockage is not considered to be drainlaying and so does not require a drainlayer. However, if the drain is opened, altered, repaired or extended in any way, a licensed drainlayer must be engaged.

That is to say, to install new drains or to alter existing drains, a person must hold a current drainlaying licence and be legally entitled to complete the work.

Certified drainlayers in Auckland

As mentioned above, a certified drainlayer is required for any work that results in a change to a drainage system on a residential or commercial property or to install a new drainage system. To ensure a specific Auckland drainlayer is certified, you can ask to see their certification card because it ensures their qualification and expertise.
