Overview

The listing is for Watts 009-040 40mm 1½" RPZ Reduced Pressure Zone backflow preventer range in 3 configuration variants

- Device Only (009-040)

- Kits with Strainer & 2 Lockable Ball Valves (009-040-LBS)

- Kits with 2 Unions, Strainer & 2 Lockable Ball Valves (009-040-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.

The engine seems to run smoother, and I’ve even experienced a slight boost in fuel efficiency. The air filter does a great job of keeping dirt, debris, and contaminants out of the engine, which can only help with the long-term performance of the vehicle. Build Quality: 5/5 The filter feels sturdy and durable. The material seems top-notch, and you can tell it’s made to last.

Plus, it seems to be designed for better airflow, which should improve overall engine efficiency. Value for Money: 5/5 Given the reasonable price for such a high-quality product, this air filter is definitely worth it. It’s a small investment that can help maintain your car’s performance and keep things running smoothly. Considering how important air filters are for engine longevity, this is an excellent deal.

Clean 2016 Prius
Size: 1-Pack
Fit my 2016 Prius good. I have had it installed for 10,000 miles and seems to work good still. With a nasty truck or old oil burner around me (windows up) I can smell some fumes but not much. Fumes might be coming from other sources like Worn window seals or firewall wire passages. If I flip the switch to recirculated air, I don't smell much. Great for the price and will buy another when I need it. Filter was great for winter driving. Better protection than stock. I forgot there was dog smell in the car.

Good air filter
Size: 1-Pack, Size: 1-Pack
This cabin air filter looks well made and fits perfectly. Installation is very easy, and once installed you can notice cleaner airflow inside the vehicle. For the price, it offers solid performance and is a great alternative to the OEM filter. The only reason I’m giving it 4 stars instead of 5 is that the material feels slightly thinner than the original filter, so it may need to be replaced a bit more often. That said, it still filters well and works as expected.
