Overview

The listing is for Watts 009-025 25mm 3/4" RPZ Reduced Pressure Zone backflow preventer range in 3 configuration variants

- Device Only (009-025)

- Kits with Strainer & 2 Lockable Ball Valves (009-025-LBS)

- Kits with 2 Unions, Strainer & 2 Lockable Ball Valves (009-025-ULBS)

The Watts RPZ reduced pressure zone backflow preventer takes the backflow prevention protection one step further than a conventional DCV double check valve. Compared to a Watts DCV, the WATTS RPZ features an additional differential release valve in the center of the valve body. In case of a check valve mechanical failure or debris caught inside, the differential release valve will open to cut off the contaminated water source to the portable water mains supply.  This Watts RPZ backflow preventer employs two in-line, independent check valves, captured springs and replaceable check seats with an intermediate relief valve. The Watts RPZ is compatible with other popular brands such as Fabco, Tyco, Wilkins and Conbraco Apollo. 

This makes the Watts RPZ the only suitable device when there are potentially dangerous cross-connections such as swimming pools or sewage processing plants, where a DCV is deemed as insufficient protections by water authorities in accordance to national plumbing codes.

A Watts 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 used 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 Watts 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.

Bought these for my 2004 M3, quality is good, fitment is OK, some gaps around the edges but you cant tell unless you look very closely. About as expected for the cost.
