Yes, there are a few different legislative and regulatory documents to consider when it comes to backflow prevention in Sydney:

The term backflow refers to the reverse flow of unwanted contaminated water that makes its way into the main water supply from either a residential or commercial system. This contaminated water will contaminate the main supply if contact between the two is made.

The Temperature and pressure relief valve on all water heaters automatically opens when they sense an excessive amount of pressure or heat in the water heater tank, alleviating any damage they might have caused. Water will leak through the valve and discharge tube after all excess air escapes from the tank.

Another function of the temperature and pressure relief valve is to release water from the tank if it gets too hot. Thermostats and temperature controls can go out in time. When the water in our hot water tank gets to a dangerous level, we rely on the pressure relief valve to expel it from the tank and through the discharge tube before it can give us 3rd-degree burns.

Toilet bidets and smart toilets are becoming more and more popular as time goes on in Australia, with various options now available on the market.

Backflow occurs when there is a sudden pressure drop in the water main outside of your property (e.g. there is a break in the system in your street). The effect of this may result in water within the fixtures (bidets, toilets, hoses, irrigation systems etc.) in your home being syphoned back into the public water main. This can potentially pollute your (and your neighbours') potable water system – and no-one wants to drink water from their neighbour's bidet!

The temperature and pressure relief valve (sometimes called a tpr valve or tp valve) helps regulate the pressure and temperature of the water inside the tank. Both can be extremely dangerous if too high.

The temperature and pressure release valve protect us when any components on the water heater go out. It’s important to remember that a pressure valve is made to discharge water from the tank if there are any issues. Figuring out if it’s leaking or not can be confusing.

The temperature and pressure relief valve work to alleviate this excess build-up to keep our water heater from exploding.  In some cases, serious measures will need to be taken to handle the extra pressure caused by thermal expansion in a closed system.

A bidet is a sanitary fixture equipped with a douche device for producing a jet of water, from a point below the rim of the pan, which can be applied to the body.
