What causes backflow?

Water flows to your property under the correct pressure, but if this pressure changes there is a chance that water could be drawn back into the water supply. Two main causes of backflow are:

A sudden drop in pipe pressure, which siphons water back into the water supply network.

If the water supply is directly connected to equipment, such as boiler or a private bore which is at a higher pressure, water is forced back into the water supply network.

WHAT IS A BACKFLOW PREVENTION DEVICE?

A backflow prevention device protects the water supply from potential contaminmation. The type used depends on the degree of risk. For example; reduced pressure zone, double check valve. The device is usually attached to the water meter on the customer side of the point of supply (water meter).

Testimonials

We have used K&B plumbing on a number of renovations and they have been great to deal with, from John, Nick & Jan right through their team, all professional, friendly and willing to work in with whatever the client wants.

or... we have used K&B plumbing on a number of renovations and quite frankly we cannot believe we still have running water!  Nick was possibly born with a box of Heineken under his arm and Jan has shares in Marisco Vineyards the maker of Ned Rose - let's be honest, John basically carries the team!

Greg & Helen - Sunnyhills

Thank you so much K&B Plumbing for coming to our rescue when we received an exorbitant water bill, and had no idea we had a leak occurring under our house.

John arrived promptly, organised the leak detectors, and the boys arrived 7.30am the next morning to dig up the concrete path and fix the leak below.  I was very impressed with the fast reliable service.  Plus when I needed the invoice urgently to seek a credit on the water bill, Jan had it to me prontissimo. 

Dianne - Glendowie

“Since mid to late 1990 I have used K & B Plumbing and I have formed a very strong partnership with K & B Plumbing. They are very knowledgeable, professional, proactive, also I am required to present 2 to 3 quotes to the business K & B Plumbing have always been competitive and I was delighted that they proceeded and completed the work. The quality of workmanship, reliability and trustworthy nature of the staff was also a major consideration.
I have no hesitation in recommending K & B Plumbing and their team for your next plumbing needs”.

Nizam - East Tamaki

THANKS, A MILLION. We were so lucky K&B Plumbing dropped everything and came to our rescue when we had a flood and saved so much more damage happening to our house. They knew what they were doing, and it was sorted pronto.

We then got K&B Plumbing back to fit a sink and plumbing our washing machine in when we renovated. It wasn’t straight forward at all. However, they made it look effortless and had an excellent solution for our layout.

Prompt, reliable service with experienced plumbers is what you get with K&B Plumbing at a reasonable price.

HIGHLY RECOMMEND
