One of the biggest risks to our water supply is backflow. This is caused when water pressure drops in the water distribution system causing water to flow in the opposite direction from residential or commercial premises back into the public water supply network. Because both homes and businesses use chemicals and other potential contaminants, backflow can be a major threat to the health and wellbeing of residents and visitors.
In the Christchurch City Council district, the backflow risk arising from the activities on a premises is assessed and it is mandatory that an appropriate backflow prevention device is installed at the point of water supply. Dewaters Plumbing & Gas are independent qualified persons (IQP) that are registered and qualified to undertake this work.
Most commercial and industrial properties are required to have a minimum of medium hazard protection at the boundary to protect the main water supply. The installation of this device is a condition of supply and is the responsibility of the property owner.
For homeowners, the Christchurch City Council provides low level protection at the point of connection to the public water supply. It does not protect water from hazards that can occur within the home. Sometimes the level of protection provided at the water connection may not be sufficient – especially if certain activities such as spa baths, swimming pools or dialysis machines exist within the premises. Protection within the premise must be carried out under Section G12 of the New Zealand Building Act 2004.

Had Charles around to install new washing machine. tub & bathroom vanity. He kept in touch to confirm he was going to be on time each day. Very tidy work done with quality and friendliness.Very impressed with the service, Highly recommend to anyone.
Charl from Dewaters Plumbing & Gasfitting did exactly what he said he was going to do, arrived on time and did a great job. Would not hesitate recommending him to anyone else.
I moved house and needed some advice on gas fitting for the property. Charles was honest and gave me realistic advice on the best way forward to save time and money. I’ve since used them again, thanks guys!
We found Charl through a friend of ours who he did a gas conversion for. He did a great job and we love our new gas hot water system. Charl came before the conversion to have a look, told us what we could expect and did a great tidy job, we did not even have to clean up, super job.
