Backflow Prevention

It's a legal requirement that all properties connected to Sydney’s Water system have an appropriate backflow prevention device installed.

Drainmaster offers fast and reliable backflow prevention services ensuring this essential device is properly fitted and well maintained.
We guarantee you a thorough and professional service as all our plumbers are fully licensed to work on backflow prevention devices and all have many years of experience.

If you do not have a backflow prevention device installed or it is faulty, polluted water can reach your main water supply system. It’s a risk which is best avoided. 
At Drainmaster, our experienced plumbers are committed to prevent the backflow of contaminated water and ensure that you get an uninterrupted supply of safe drinking water.

Backflow generally results from a drop in water pressure. This creates negative pressure in the water system allowing contaminated water to flow back from the ground or other sources and mix with clean drinking water. This can happen in places such as your toilet, basins, sinks and even swimming pool.

Contaminated water as a result from backflow can cause serious illness or in severe cases fatalities. 
We offer inspections and testing of backflow devices and where necessary we will either service or install a new device.

Don’t put yourself or your families health at risk. Call Drainmaster today to ensure your Backflow is safe.
So if you are looking for a reliable licensed plumber in Sydney or on the Central Coast you've come to the right place.

Our teams are working in your area today!

  • Somehow our kitchen sink had become blocked, considerably blocked. We have a plunger in the house so my husband gave it a go but it just wouldn't budge. This was going to be a tricky job to fix ourselves. We gave Drainmaster plumbing and hot water a call later on that day to come and clean out our blocked sink. They found the time to come the next day which was just perfect. The kind member of staff explained that with such a blockage it would have to cleaned out with a high pressure jet. He quoted a fair price and we were more than happy to hand the job over to them. They did a wonderful job and left my kitchen clean and tidy. I'd be more than happy to refer Drainmaster to my friends and family.
  • Not so long ago I had to call out drainmaster due to a blockage in my drains, I wanted to get it fixed before it started to overflow thus creating an even bigger problem. I was truly amazed at their competence when they arrived. In no time they had cleared the blockage and my drains were flowing at their maximum capacity once again. Even more enjoyable was that they provided me with a free CCTV drain inspection so I could see the state of my drains, I was glad about this because it turned out the drains were in need of some future work. Drainmaster plumbing and hot water will be getting another call from me soon and im more than happy to hire them for any job again.
