Christchurch City Council regulations require all businesses to have backflow prevention devices installed, and these must be tested and checked every year by an Independent Qualified Person (IQP) to ensure they are still compliant. Our team at MJ Robertson are IQP certified and can install backflow prevention devices in your business to ensure everything is up to standard. We can also carry out the yearly required testing and checking. Backflow can lead to contaminants and bacteria entering the water supply of others in the community so it’s essential that these systems are maintained. Contact us on 03 366 6195 to speak to one of our team about backflow prevention today.

I had a hot water cylinder changed in the ceiling which was quite difficult to access. I am quite fussy and they did an excellent job. They turned up slightly early. They cleaned up and took the old cylinder away. The quote seemed to be spot on for time and also recommended to change old valves which was a great idea. I did need to get the quote itemised but when done it all made good sense. Well done and thanks.

Excellent same day service, friendly and great work to boot! Highly recommended. Thanks very much for such a quick response, especially as I haven’t used your services before. I certainly will again should the need arise
