Overview

The listing is for Watts 009-015 15mm 1/2" RPZ Reduced Pressure Zone backflow preventer range in 3 configuration variants

- Device Only (009-015)

- Kits with Strainer & 2 Lockable Ball Valves (009-015-LBS)

- Kits with 2 Unions, Strainer & 2 Lockable Ball Valves (009-015-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.

Practical Slow Feeder Bowl, Works as Expected
Color: Blue
I tried this slow feeder dog bowl for my pet, and overall it’s fairly well made. The suction cup keeps the bowl in place on smooth surfaces, and the reinforced rim feels sturdy. The puzzle design slows down eating, though it may take some getting used to for certain dogs. Made of BPA-free silicone, it seems safe and easy to clean. It works for a range of dog sizes, though the 3-cup capacity might be a bit small for larger breeds. Overall, it’s an okay option for slow feeding.

From 2 minutes to 10—he actually enjoys his meal now
Color: Orange, Color: Orange
I’m really happy with this slow feeder, and my dog seems to love it too. He used to just chomp his food down in about two minutes, but now he actually takes his time and it keeps him busy for at least 10 or 15 minutes. I usually mix a little dry food with some soft food and use the included blue spatula to really mash the soft food down into the grooves. Doing that makes him eat even slower because he has to lick it out, and I think he enjoys his food a lot more now that he isn't just rushing through it. It’s actually pretty cool to watch him because he’ll eat a little, then sit or lay down and just watch his bowl before getting back to it. He’s very territorial about his food and doesn't want the cat coming anywhere near it, so he stays right there to guard it while he takes his breaks. The suction on the bottom is extremely strong and stays put on the floor, so I don't have to worry about the bowl sliding around. I even tested it on a hallway wall and it stuck so well I was worried about the paint, but I figured out that if you pull it down instead of straight out, it releases just fine.

Easily Replaces the Linking Mat
Color: Orange, Color: Orange
This slow feeder bowl has been a great upgrade from the flat lick mat I used before. The deeper design allows for so much more food, which is perfect for spreading soft foods like yogurt or peanut butter. The textured sides really help hold everything in place. It’s made of flexible silicone but still holds its shape well. I love that it comes with a mini spatula-a handy little bonus for spreading food. I’ve also put it in the fridge to freeze treats, and it works great for longer-lasting enrichment. The suction base keeps it securely on the floor, which is important because otherwise Maverick would absolutely try to run off with it! 😊 It’s also dishwasher safe (top rack), making cleanup easy. Overall, a well-designed, practical slow feeder that both my dog and I are happy with.

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.
