What are Backflow Prevention Devices?

Backflow devices prevent harmful contaminants from entering the city’s main water supply. If back-siphonage or back-pressure occurs, it can pollute the potable drinking water and cause local residents to fall sick.

Double check backflow device (DC) and Reduced Pressure Zone Backflow device (RPZ) are commonly used to prevent backflow. At Ryan Old Plumbing, we install, test and maintain DC valves and RPZ backflow preventers. RPZ valves are installed in high-risk areas whereas DC backflow preventers are installed in low-risk areas. Your backflow prevention device will be installed in accordance with the hazard rating of the property.

  • Irrigation system connected to mains water supply
  • Fire hose reels or hydrants

Excellent service. So good to deal with. I recently renovated my bathroom and the guys were so helpful. They handled a few curveballs and got my bathroom up and running in a timely manner...

Oliver Talbot

I would like to thank the service of the experienced plumber who came to quote the installation of tap fittings I purchased myself. Nothing was a problem and he installed them on the spot...

Mary McKinlay

Fantastic! Ryan was friendly from the first call and had a young bloke attend my leaking hot water in Manly within half hour, had the job completed within the next half hour and kept me up to date...

Plumber FAQ

How to fix a leaking tap?

Leaving a leaking tap unfixed is super easy to do – you hear it, you complain about it and it wakes you up at 3 am. You then say a few select words and then likely go back to sleep again until it wakes you up the next night.

That is why now is the best time to fix your leaking tap! Whether you choose to complete the job yourself or call in the professionals, you will be more than glad when that pesky tap isn’t leaking anymore. Although fixing a tap yourself can be a simple task if you know what you are doing, it can become messy, difficult and expensive if it isn’t done right. This is definitely something to consider when you are looking at fixing your tap.

What is considered a plumbing emergency?

Although a leaking tap is not a serious emergency, it could be. Extreme plumbing emergencies include those that damage or threaten lives (gas problems, water leaks) - especially when adverse health effects are already being felt. Other critical situations include sewer leaks, major flooding and burst pipe.

Whatever plumbing problems you may have, as long as they greatly impact you, we will treat it as an emergency and will fix the issue ASAP.
