Overview
The APO PRV20F 20mm 3/4" inline pressure reducing valve is Australia Watermark approved and features a pressure adjustment range of 150-600kPa with a factory setting at 500kPa. The APO PRV pressure reducing valve features the same threads, fitments and similar physical sizes with many other valve manufacturers such as Reliance, AVG, Tomson, AW, Nefa and Reflex. This makes the APO PRV pressure reducing valve a perfect direct replacement to an existing valve with no plumbing pipe modifications required.
The pressure reducing valves are commonly used in hot water services such as electric, heat pump, gas storage and solar hot water heaters across all mainstream brands in Australia such as Rheem, Vulcan, Rinnal, Dux, Aquamax, Thermann, Apricus and Solahart. The pressure reducing valve employs a membrane design inside with a stiff pre-loaded adjustable spring, opposed to a sliding piston mechanism found in a pressure limiting valve which often causes failures from clogging up. This design feature makes a pressure reducing valve more reliable than a pressure limiting valve, while functioning the same way in this application.
In real world installations, it is sometimes found that pressure limiting valves cannot limit pressures sufficiently in places where unusually high street mains pressures are present. This can cause troubles with ECV and PTR valves leaking on hot water services. The pressure reducing valves can be used in such situations and offer a far better pressure control from our in field experiences over the years in our own plumbing jobs in Brisbane.
The pressure reducing valves can also be installed after water meters or just before entering houses. The pressure reducing valves can ensure a stable water supply pressure, despite the pressure fluctuations in the mains from the streets.
The pressure reducing valve comes with a BSP 6mm test plug inbuilt, where an optional pressure gauge can be inserted for pressure measurement at the outlet. The optional pressure gauge is shown in the photo gallery and can be bought for extra. It must be noted that the pressure gauge is only intended to be used as a measurement tool and must be removed after use, as it could rust inside out if left in a wet environment for prolonged periods of time.

The only toy my dog wants
Color: Gator, Size: Large, Color: Gator, Size: Large
I have a 9 year old, 12 pound chihuahua, and this toy is everything to him. Ever since he was a tiny puppy, he’s liked toys that are at least as big as he is. Once I got him this, it was the only toy he’d play with. He carries it everywhere. He likes to chew on it, and sometimes pulls apart the threads. He LOVES to play tug of war with it, so the handle is awesome. It has so many squeakers, which is also a plus, and it holds up well for our little guy. We’ve probably had at least 10 of this same toy, we get him a new one about once a year when it starts to get worn. I worry that if they ever stop making it, he’ll be depressed lol. It’s been with him at all life stages and he doesn’t go anywhere without it. Really can’t ask for more when your dog loves a toy this much

Lots of squeakers in this one!
Color: Gator, Size: Large
Our rescue dog is a power chewer so this one doesn't last long, but I still gave 5 stars because it's not advertised for power chewers, so I knew what we were getting when we bought it. So why did I buy this for our dog? The number of squeakers... the dog goes nuts for those and it makes the toy last longer because she will only play with the ones that still squeak.

NOT for aggressive chewers!
Color: Lion, Size: Medium
My aggressive chewer had destroyed this in 3 minutes! Chewed off the ears, and chewed apart the body to try to get to the squeaker - it was in the trash 5 minutes after I gave it to him! Yes, the seams are tough, but he easily chewed around them. Don’t buy this if your dog is an aggressive chewer!

Somewhat durable.
Color: Elephant, Size: Small
My dog loves these toys, I think it's the squeaker. I've tried several and this elephant one holds up the best.

Not tough enough
Color: Elephant, Size: Small
It might be tough, but my 26 pound dog managed to rip it open in record time! The only good thing, the squeaker is a long plastic one and easier to grab before she can swallow it!
