Overview

Australian Valve Group (AVG) PTR15-1000-LF 15mm (1/2") 1000kPa PTR Pressure and Temperature Relief Valve (also known as TPR valve) is cross compatible with other popular makes such as Reliance HT55 PTR valve with same fitments and functions.

During the hot water services' heating cycles, the volume of water will expand as the temperature increases. This volume expansion creates excessive pressure inside the water cylinder and must be regulated. The AVG PTR valve is designed to regulate and relieve the pressure in hot water services by dripping in a controlled manner. 2-5L a day of dripping is normal, depending on the hot water usage and the amount of heating going into the water.

The AVG PTR valve is also a mechanical protection device for the hot water services. In rare occasions of faulty thermostat or heating element, the hot water service can overheat and build dangerously high pressures. When the AVG PTR valve senses this abnormally high temperature and pressure, it will dump large amounts of water in hundreds of liters for an emergency pressure relief.

A functioning PTR valve is a requirement by law in Australia for safety and the AVG PTR valve is approved under the Watermark standard. The AVG PTR valve comes with an insulation jacket and allows for a professional look and minimal heat loss.

A PTR valve usually has a life span about 5 years and needs replacing if you notice excessive water leakage in a stream instead of a controlled dripping. The AVG PTR valve is cross compatible with many other brands such as Reliance, Tomson, Nefa and Reflex.

The AVG PTR valve fits perfectly with mainstream heat pump, solar, electric and gas storage water heater brands such as Rheem, Vulcan, Rinnal, Dux, Aquamax, Thermann, Apricus and Solahart.

Trixie Flip Board Dog Enrichment Toy – Great Starter Puzzle, Best for Beginner Dogs
Color: Flip Board, Size: Level 2
I’ve been using this with a high-energy, working-breed dog, and it’s a solid beginner-level enrichment toy—especially for dogs new to puzzle feeders. What works well: • The design is simple and intuitive. My dog learned the flipping lids and sliding compartments quickly without frustration. • It’s great for short mental stimulation sessions or slowing down treat time. • The non-slip base helps keep it in place on hard floors. Things to consider: • This is a Level 1 puzzle, so once your dog understands it, they can solve it quickly. • The compartments are on the smaller side, so it works better with small treats than full meals. • Best used with supervision if your dog tends to paw or chew at toys. Best use case: Ideal for puppies, beginner dogs, or as part of a rotation of enrichment toys. More advanced dogs will likely need something more challenging to stay engaged. Bottom line: A well-designed starter puzzle that’s easy for dogs to learn and use. Not the most challenging option long-term, but a good addition to an enrichment routine.

My rabbit loves playing with this, and of course getting treats!
Color: Turn Around, Size: Level 2
My bunny absolutely loves the TRIXIE Activity Around Puzzle Feeder! It keeps her engaged and mentally stimulated for long periods, making it a great source of fun not just for rabbits, but for cats and small dogs too. The design is intuitive and easy to clean, which I really appreciate—it takes just a quick rinse or wipe-down after each use. Despite regular use, the toy has proven to be very durable and holds up well to enthusiastic play. One of the standout features is that it’s surprisingly resistant to chewing; even with my bunny’s constant nibbling, there’s barely any visible wear. The compartments are just the right size for small treats, encouraging pets to think and interact with it. I love that it adds enrichment to my pet’s routine without creating extra work for me. Overall, it’s a well-made, multi-species puzzle toy that brings a lot of joy to curious pets. It is very quiet during use and doesn't make a noise.

He was confused, I was amused!
Color: Turn Around, Size: Level 2
This toy was quite well made, the materials are solid and once assembled, its very sturdy! Super easy to put together too. It comes with two kinds of lids for the test tubes, three little holes (intermediate/ difficult) and one big hole (beginner/easy). So the actual toy was really nice. There was only one problem...for some inexplicable reason...my dog (3 yr/ 20lb/ shorkie) was afraid of it! He's used lots of puzzle / game toys in the past, but for some reason this one weirded him out. No matter what I did, I couldn't get him to even try moving the test tubes. The farthest I got was having him eat a treat off the edge of a test tube once or twice (hence the video, there's a piece of chicken sitting on the top). Mostly he would just growl at the toy or eye it suspiciously, and then run away. I would describe his overall attitude as agitated skepticism with a hint of annoyance...specifically toward me! (As if saying "what the heck is this thing??") I will say the customer service was pretty good. And I definitely got some personal entertainment watching my dog run around and growl at the toy that was just sitting there. (:

Can't beat the price if you have smaller dogs
Color: Turn Around, Size: Level 2
This is my 2nd one, which was bought for my mom's dogs. They absolutely love it when they come to my house. I live that they have to get their nose off the floor to figure it out and that there are more than 1 tube that they have to flip (think about). My only thumbs down isn't a big deal but would be the hard base. The treats fling off this base and can end up anywhere in the room. I think if it wasn't so hard, they wouldn't have to walk away from the activity or have to fight over who get the "reward" (It's usually the other dog waiting to chase where they fly off to). It doesn't flip over unless they run into it which doesn't happen often, although our dogs are all under 15 lbs. Imnsure if a bigger dog were to use this, it wouldn't stand up well and may break. It was easy to put together, and functions very well. Our dogs think this is the most fun toy out of all the interactive togs we have (which is A LOT).

Amazing!!!
Color: Turn Around, Size: Level 2
This is an amazing mental stimulation toy for my dog! And it’s a perfect one for dogs who are learning. He picked it up right away and loves it! I can’t wait to get the other ones they have. Seriously so amazing. My very active Aussie can spend 30 minutes doing this and not get bored.
