Backflow is the reversal of the normal directional flow of water supply within a plumbing system. When the delivery main is at a lower pressure than the internal plumbing system, backflow (back siphonage) occurs. This may be caused by a ruptured water main or during excessive demand periods. Alternatively, it may occur if a water pump (such as a bore pump), is cross connected to the internal water plumbing system and is pumping bore water at a higher pressure than the water main pressure. Water backflow can cause potentially polluted water to gain access to your drinking water supply system.
Backflow incidents can be serious and without the installation of authorised prevention devices, you could be subject to imposed penalties. Local/Regional Councils require backflow prevention devices to be installed by licensed plumbers and have annual testing, which then must be formally reported through to the relevant department. Let our team relieve the stress of your backflow concerns with our prompt and professional testing and prevention services. Our team of licensed plumbers at Alexander Gas and Plumbing Co., will install top quality devices and conduct annual testing to report to the appropriate authorities.
Very punctual, discussed various options and completed the work at a very competitive price.
Friendly, efficient and knowledgeable service. Thankfully I was asked if I wanted anything else done which prompted me to get work done that I had put off. Serviceman was not pushy. I am happy with the thorough job done. I would recommend this company and will use them again
Highly recommend these guys. I reached out Friday for some non urgent work and was booked in first thing Tuesday morning. Turned up right on time (always a bonus), very polite, explained everything and cleaned up afterwards! Very economical costs as well. Thanks guys!
Thanks for the prompt service and fantastic job done.
Very happy with the work completed. Everyone I spoke to was friendly, professional & very efficient. Good communication & made the extra effort to help us sort out our problem. Great job, I'd have no hesitation to recommend to others
We do appreciate the work that was performed by Rhys, he was very professional in his approach and honest with any of his findings, it was a pleasure to have him on site. I appreciate everything you guys have done right from the start, all your work is appreciated and I will definitely be using you guys from here on in for any further works required, as it isn't everyday you find trades that make you glad you chose them.
I couldn’t be happier with the service and workmanship provided by Richard. He was at my house within 2 hours of calling and fixed up all the problems I had with my water tank pump. I especially appreciated the phone calls to keep me updated on the progress. I would definitely recommend Alexander Gas and Plumbing to anyone.
Richard did a great job doing the installation for a gas-powered coffee machine on a tricycle cargo bike. Not exactly an everyday job but he did it quick and professionally and clearly knows what he is doing. On top of that, he is really easy going and clearly explaining what he is doing. Will definitely ask him again for the next job.
A prompt and friendly approach to plumbing. No time-wasting, good advice on product and professional installation. Very cost-effective as well. Thanks for a job well done!
I have used Alexander Gas & Plumbing Co on a number of occasions at two properties. Jobs included repairing a broken underground sewer pipe, installation of new hot and cold water services, installation of new sewer pipes for a house extension and extension of gas pipework for kitchen appliances. I have found Richard to be prompt – he’s there when he says he will be there, he’s courteous, he cleans up any mess and is efficient. I highly recommend Alexander Gas & Plumbing Co to anyone needing plumbing work done without hassle.
Stop looking! These guys are Awesome. Couldn’t be happier with the service and workmanship of Richard today, professional and super friendly. He went the extra mile and cleaned up brilliantly when he was finished also, I highly recommend
