Quick affordable plumbing repair. Explained what needed to be done and how much it would. Great service and will use again.
Jem arrived on time. He was polite and cheerful. Good service....He thoroughly explained what he was going to do.- I feel much better informed about taps now. So much easier to turn taps in and off with the ones Jem installed.. thanks very much.
Amazing service, prompt, professional & very very knowledgeable! Completely wrapped in these guys, took a load off our minds knowing they knew what they were doing on this massive & costly fix! Karen & Peter Voigt
We recently contacted Jetset Plumbing to investigate a water leak. They responded quickly, located the problem and quoted on the spot. Upon acceptance of the quote, the work was carried out the next day. They were extremely efficient and professional when working and the area was cleaned up when the work was completed. Great job guys - thank you! I would have absolutely no hesitation in recommending this company.
Tony came out to inspect the issue, we both thought it wasn't bad but once he got the camera down we found the actual problem, even though he didn't fix the issue he stated that jetset has an alternative fix that would do the job and at cheaper price. Making my booking now to get the job done. They have the easiest booking system with their chat online and also would recommend them to anyone in need. Thanks Jetset, thanks Tony. Kind Regards. Mai.

Amazing service.. all the boys who attended were so pleasant and friendly..work was carried out effectively and efficiently and the repair job was a amazing price.. would highly recommend them and will definately use them again.. THANKS JETSET ,Suzanne Gallagher
Honestly, I am so impressed with this business. I like to support local when I can, so I called them during the Christmas holidays when our water pressure had gotten so bad, we couldn't even use the tap and shower at the same time. Firstly not only did they answer the phone over the holidays, but the professionalism on the call was surprising refreshing. They arranged the plumber to be on site the next day. The plumber (Chris) called 20 mins out, then arrived on time, was genuinely a good bloke, and then proceeded to just get it done. I can honestly recommend this company, and I have saved them on my phone for future use - I will not go to anyone else from now on.
Nick, Steve, Dave and Blake were amazing. Blake came and looked for the main problem then gave me the quote for repair. They all arrived on time and didn’t miss a beat. I am so happy with their work and craftsmanship. Left my yard in great condition when they left. Best plumbers I have ever had to deal with. Well done guys.
Phone call resulted in booked response next morning. Advice on day that plumber running a little late was much appreciated. Mike arrived and without any pressure discussed our needs and offered suggestions. Mike installed 2 toilet systems leaving no mess behind. Very pleased with the company work practices and attitude. Thank you Mike and Jetset office staff. Bob and Rhonda
Fantastic service, I have used jetset plumbing for a few years, they always turn up on time do a great job.
great service, the 2 guys were very well versed in customer service, very polite and friendly and did their job with real urgency so I could get my day started. will use these guys again in the future 100 percent.
Glen from Jetset Plumbing came out today, extremely personable and professional. Completed all jobs required in a timely and effective manner. Totally transparent and thorough in all aspects of work required. Photo proof evidence before and after, plus full report. Totally happy with work and wouldn't hesitate to call them again. I would highly recommend for any plumbing services. Thanks Glen, really appreciated your professionalism and effective service

RPZ Valve Test plumber

What is Backflow plumbing?

Backflow is a plumbing term that is used to describe when water flows in the opposite direction. If backflow were to occur in your home or business, it could cause contamination to your water supply. If left for too long, water can become unsafe to drink or bathe.

Backflow testing is required every 12 months for property owners that have; an irrigation system, fire hose reels, commercial machinery connected to the mains or an underground water tank that has a mains water backup.

What causes Backflow?

There a few causes for backflow to occur:

1. Reduced pressure in the water main.
Water systems are designed so that water flows under pressure to and from properties. However, if this pressure is not maintained, water could be drawn back into the water supply system. Many things can affect water pressure, including; a break in the main, water being pumped from the main supply in a fire, water outlet on the property is higher than the main, and a customer is using water at a high pressure than the pressure supplied by the local council.

2. A cross-connection between the drinking water supply and a contaminated source.
When water pressure drops, it creates a vacuum in the water supply system. Sometimes this allows liquid from a contaminated source back into the drinking water supply. Some incidences where this can occur include; in chemical plants where chemicals come into contact with the water supply, when a hose is left running in a container with chemicals, pipe work that allows recycled water to enter the drinking water supply.

3. A nearby property uses the water supply.
A dangerous chemical could get into the water mains which lead to a nearby property. If this contaminated water is then used, residents of the property could be seriously or fatally injured.

Why do you need Backflow Valve Prevention?

A backflow prevention device allows water to travel in one direction but prevents it from travelling backwards in the opposite direction. Every person’s garden and landscape around them have countless things that can make you sick if you drink them. Irrigation water alone has toxic chemicals (fertilisers, pesticides etc) and animal waste (urine and faeces) all through it. These harmful chemicals and pollutants will contaminate your drinking water if you do not have a backflow prevention device.

If you are on a community water system, the water could flow back up the pipes and poison your neighbours. The valves that turn on and off your water system are not sufficient to stop backflow, the purpose of a backflow preventer is to protect you when these valves inevitably break or leak. Many people think that the water pressure in the water system is enough to keep the water from flowing backwards.

Most of the time this is correct, however, there are times when the water pressure drops in the supply system allowing backflow to occur. If a water company has turned off the water supply to repair or install a new pipe, the pressure will drop, the same thing opens when fire-fighters pump huge amounts of water out of fire hydrants.

Backflow Pipes and Valves

What are the backflow prevention requirements in Queensland?

All local governments are required under state legislation to maintain a program for the registration, maintenance and testing of backflow prevention devices installed in their area. Backflow prevention devices stop the reverse flow of water from what could be a polluted source into the water supply. Backflow prevention devices are fitted on:

Irrigation systems that are connected to mains water supply

Fire hose reels

Commercial or industrial machinery connected to the mains

Water outlets close to pollutants, grease traps or chemicals

Underground water tanks that have mains water backup


Whenever a plumber fits a backflow prevention device, they are required to submit the report to the Backflow Register. Each year your local council will issue an Annual Registration Fee Notice and Testing Reminder Notice to the device owner, reminding them to arrange for their devices to be tested before 31 December. State legislation requires owners to register the device with the local government and have the device inspected or tested by a plumber endorsed for backflow testing.

What backflow device do I need?

Each property is designated a hazard rating (low, medium or high). You will need to consult an accredited backflow prevention plumber to determine your property’s hazard rating and the type of device needed. Low hazard properties should install a non-testable backflow prevention containment. Medium hazard properties must install a testable double-check valve assembly. High hazard properties must install a registered break tank, reduced pressure zone or registered air gap. If your property is deemed as a medium or high hazard you will have three months to install the device.

Why do you need a backflow valve replaced?

As a general rule of thumb when it comes to deciding to replace or repair a backflow device – if the repair cost exceeds 50% of the cost to replace the device, the best and most economical option is to replace it. Today, there are different materials that backflow valves are manufactured in: ferrous metals, non-ferrous metals and non-metallic materials. Non-ferrous materials include stainless steel which has become the preferred material for newer backflow assemblies. There are a few good reasons to make the switch to stainless steel backflow assemblies: they are up to three times lighter than ferrous backflows and easier to install; new valves are typically less expensive than a replacement of the old design; stainless steel will not corrode so there is no need to worry about epoxy chipping.

What are the different types of backflow preventers?

Reduced Pressure Valve (RVP)

For a commercial site (any business property, apartment complex or condominium) a RVP is the industry standard. This backflow preventer provides the highest level of protection and if anything were to go wrong, a commercial property owner is held to a very high standard of liability. Even if you reside in a residential family house, if you plan to use; fertigation, fertiliser, pesticides or apply anything other than pure water in your irrigation you must install and RVP. This includes products that are labelled as ‘organic’, ‘safe’ or ‘natural’ as while they may be safe when dispersed in the air, they will become much more toxic when concentrated in the water.

Double Check Valve (DC)

A DC valve simply has two spring-loaded check valves with a shut-off valve on either end. The DC valve is the only backflow preventer that does not have a vent that allows air to enter the lines or to allow water to escape when backflow occurs. A DC valve is the only type of backflow preventer that can be installed in a large vault with unblockage drainage.

Pressure Vacuum Breaker (PVB)

A PVB is generally installed on the mainline leading to the control valves. It must be installed above ground and be 150mm higher than the highest sprinkler head controlled by any of the valves. A PVB backflow preventer may spill water from under the cap when backflow occurs, as such, it should be installed in a location where water spillage would not cause problems.

Who can replace, install or remove a backflow valve?

Only a licensed plumbing contractor can replace, install or remove a backflow device. When a backflow prevention device is replaced, removed or installed it is the responsibility of the licensed plumbing contractor to submit the correct form to the Queensland Building and Construction Commission.

How much does a backflow valve cost?

The cost of a backflow valve differs drastically for each situation. Depending on how many valves you need, your hazard rating and what surrounds your area, the price will fluctuate. As a general rule of thumb backflow preventers fall into the following order, from most expensive to least expensive:

$$$ Reduced pressure valve

$$ Double check valve

$ Pressure vacuum breaker


Backflow RPZ Valve

What is a RPZ Valve?

A reduced pressure zone valve (RPZ) protects water supplies from becoming contaminated or polluted. This specific device is designed to be installed on safe drinking water lines to protect from backflow and potential contamination of the supply. An RPZ valve provides protection where a potential health hazard exists.

What is a RPZ Valve Test?

A RPZ Valve Test is required to be conducted annually, it tests for backflow and ensures the device is in good working order. Only a licensed plumber can carry out an RPZ valve test. Once the test is completed we will send the correct paperwork through to your local government.

What is a RPZ Valve?

RPZ (reduce pressure zone) and DC (double check) valves differ in that RPZ valves are preferred for higher hazard zones whereas DC valves are preferred for lower hazard zones.

Is your backflow prevention device in proper working order? If so, you will be drinking and bathing in clean water with no contaminants. However, if it is not working properly, contamination will occur, it is vital to have regular backflow testing to prevent this.
