Yes. Municipal water utility companies generally treat tap water. One of the most important things they do is add a solution to the water to kill biological threats like bacteria and viruses. However, water treatment also leaves trace amounts of residue.

All Plumbing Online stocks and supplies both Watts DCV and RPZ in full range of sizes and kits configurations. Just ask me any further questions if still unsure between DCVs and RPZs. All Watts DCV and RPZ are Watermark approved and are one of the most popular kits in Australian market due to its reputations and values for money.

The contaminants in tap water which gets past the final levels of filtration are called Total Dissolved Solids (TDS). TDS are typically comprised of metals, chemicals, organic materials, and minerals.

A RPZ is usually significantly more expensive than the equivalent DCV counterparts, even though they may look very similar. Customers need to check with the local plumbing authority to ensure the correct backflow preventers are employed for the jobs.

30 days worry free return is offered for peace of mind. All returned items must NOT be installed or with any water running through them. The original packaging must be supplied in resealable conditions.

It’s time to understand that the water running through the average American home isn’t as pure as we thought. You need to start treating your water as seriously as we do.

One can’t really say since they both have their purpose, but there are definitely pros and cons to bottled water and filtered water.

Chorine/chloramine in small amounts should not have major adverse health effects. However, it does affect living standards and comfort levels. Chlorine/chloramine can irritate the eyes, cause itching, make your skin dry, and make your hair brittle. It also will add taste or smell that is similar to pool water.

Our water bills would most likely skyrocket if water companies operated with the goal of removing all TDS. Instead, they treat water so that it has “acceptable levels” of TDS to keep tap water affordable.

In other situations where the cross-connections contain hazardous chemicals, such as swimming pools or sewage processing plants, the potential contamination can be lethal or dangerous. The double check valve DCV backflow preventer may be regarded as insufficient protections by the plumbing authorities. In this case, a RPZ reduced pressure zone backflow preventer must be used instead. A RPZ reduced pressure zone backflow preventer's design differs from the DCV by featuring an additional differential release valve as a mechanical fail-safe device which will open and dump contaminated water to isolate the mains water supply.

Using a quality water filtration system for your tap water will give you great-tasting water with high standards.  The great thing about filtering your own drinking water is that you know that you’ll get quality water with a quality refining system, you have a reduced carbon footprint since you’re not using single-use plastics, and you save more and more money over time.

On the other hand, each bottled water company has different standards for their respective products. The water pre-treatment has different properties, their treatment methods are different, and their packaging is different. Plastic water bottles are also not environmentally friendly and can leach plastic and chemicals into the water. These factors are why each brand of bottled water has a distinct taste and smell to it.

The use of the Watts double check valves DCV back flow preventer must be in accordance with the Australian national plumbing codes and local plumbing requirements, who shall deem the applications as non-health hazardous in nature. The local authorities will have the jurisdiction regarding the vertical orientation, frequency of testing or any other requirements.
