Overview

The listing is for Watts 007-032 32mm 1 1/4" DCV double check valve backflow preventer range in 3 configuration variants

- Device Only (007-032)

- Kits with Strainer & 2 Lockable Ball Valves (007-032-LBS)

- Kits with 2 Unions, Strainer & 2 Lockable Ball Valves (007-032-ULBS)

The Watts double check valve DCV backflow preventers are designed to protect portable drinking water in the mains supplies from cross-connections from water applications such as irrigation, fireline or industrial processing. The Watts DCV is compatible with other popular brands such as Fabco, Tyco, Wilkins and Conbraco Apollo.

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. 

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. 

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. 

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.

I’ve been using this device on my patio and it actually makes a noticeable difference. It’s compact, easy to carry around, and I like that it’s rechargeable. The coverage is decent for small outdoor areas, and the refills are simple to swap out. Perfect for camping or relaxing outside without constantly swatting bugs. Definitely worth it for the price

This product is completely useless. I turned it on, and flies swarmed all around it—even landing right on top of it. It's false advertising. Don't buy it.
