Specify a plumbing system that's 'fit for purpose'.
A sanitary plumbing system, also known as a DWV (drain, waste and vent) system, transports harmful waste water from a home or building to the sewer network. This system normally consists of a network of uPVC pipes and fittings and forms an essential service in the operating health of every home and building in New Zealand
A leak or failure in any part of this system can have severe consequences for both you and your clients. Factors include:
- Time: A sanitary plumbing system is non-pressure, so a leak could go undetected for a long time.
- Health: Undetected waste in wall cavities or in the ground creates very real health concerns.
- Materials: The system is behind the wall so any repairs will be costly. Fixing leaky plumbing incurs major costs even for a minor leak.
- Reputation: As has been seen with the leaky building situation, the reputation of all those involved in a project can be at stake, particularly those responsible for specifying or installing.
Currently, many buildings are being installed with a mixture of DWV pipes and fittings from a variety of domestic and overseas suppliers and manufacturers. A recent release from the Building Industry Federation (BIF) warned the building industry to take care to ensure that imported products are “fit for purpose” and stated:That in the case of the PVC piping the wrong colours, non-compliant with standards, were being supplied and was a further blight on those who made it available to consumers. Misleading quality and appraisal markings were also being used in association with the products.
If any of these imported PVC pipes and fittings do not meet New Zealand quality standards, the chance of a failure increases, as the standards are very specific on critical product attributes such as bend radius and wall thickness. This concern is reflected at a government level with the MBIE to report back to Cabinet by the end of June on an inquiry it is undertaking regarding construction industry materials and products.
