Overview

The AVG ECV15-1200-LF 15mm (1/2") 1200kPa ECV expansion control valve is used to regulate the water pressure inside hot water services, including heat pumps, electric, gas storage and solar water heaters across all mainstream brands in Australia such as Rheem, Vulcan, Rinnal, Dux, Aquamax, Thermann, Apricus and Solahart. 

The AVG ECV expansion control valve features the same threads, fitments and similar physical sizes with many other valve manufacturers such as Reliance H50, Tomson, Nefa and Reflex. This makes the AVG ECV valve a perfect direct replacement to an existing valve in an old hot water heater. 

The ECV expansion control valve regulates the pressure caused by water volume expansions during normal heating cycles in a hot water service. The ECV expansion control valve relieves this increase in pressure by a controlled water dripping into a drain line typically of 2 to 5 liters per day depending on the hot water usage.

The ECV expansion control valve is color coded and used in conjunction with a matching color coded PTR pressure temperature relief valve of a higher pressure setting in a hot water system. Therefore, the ECV valve is designed to open first before the PTR valve does. Because the ECV expansion control valve is installed to the cold water supply line, this means the cold water is dripped out first, instead of hot water otherwise via the PTR valve. This cold water dripping feature ensures a better safety and promotes energy saving at the same time. The reduced duty cycle on the PTR valve can promote the PTR valve service life span too. 

A functioning ECV expansion control valve is a requirement by law in many Australian states by plumbing authorities for safety. A typical sign for a faulty ECV valve is when there is a large amount of water leakage in a stream, rather than a controlled dripping. The worn out or leaking ECV valve must be replaced immediately. 

Engineer's Notes

The small black plastic part opposite the discharge port is called an auxiliary and serves as an emergency fail safe device by blowing itself out in case of a blockage in the discharge drain pipe. However, this auxiliary can become a failure point itself over time by unintended leakage or blow out due to manufacturing defects. The auxiliary is a threaded part and can be easily screwed in/out. The auxiliary can be replaced cheaply, instead of buying the whole valve.

Although a faulty ECV valve itself is the most common cause for excessive leakages, this can also be caused by a faulty or insufficient pressure limiting valve, which regulates the inlet cold water supply pressure from the street mains into the tank. If the pressure limiting valve is faulty and allows excessive pressure into the water system, the ECV can leak when not faulty. In some extreme cases, the local mains street pressure may be so high to a point that the pressure limiting valve can become insufficient to limit the pressure to a typical 500kPa even with no faults. In these scenarios, a pressure limiting valve may need to be replaced or a pressure limiting valve must be used instead to limit the inlet water pressure sufficiently. 

The plumbing codes require the ECV and PTR discharge pipes connected to a nearby drain or roof down pipes, so the discharging water is not directly dripping to the ground. In cases of no or difficult access to an actual drain, a fake drain may be allowed by the plumbing rules by digging a hole on the ground and make up a fake drain using a PVC pipe section.

Almost Perfect
If you’ve ever seen these things, the foldable ones are just as good as the standard ones. I just wish when you folded it up there was a way to lock it into that position. When you unfold it to play, you lock it into place with the orange locking slide so it doesn’t fold up on you. But when you’re done playing and fold it up, there’s no way to lock it into that position, it can keep unfolding if you carry it around with you, plus the orange locking slide keeps sliding up and down. It’s not a huge deal, but they could’ve made it better.

Awesome for hyper dogs
Color: Blue
AWESOME - I have a dog that just won't stop trying to get me to play with him ALL day! I turn this thing on and he goes nuts and tires himself out...without any help from me. The cover got torn off and torn up in minutes but he doesn't care. He just wants this ball. My other dogs, who are older, aren't really interested. But if you have a hyper dog this is the thing for you and them!

Great entertainment, charges quickly!
Color: Orange
Super fun entertainment for dog! Toy ball charges quickly and the charge lasts for at least an hour of playtime for the dog. There are 2 modes. one mode Just lights up, which makes it easy for pet to chase it. The second mode not only lights up, but it also wiggles on the ground Randomly and speeds off in a direction on its own, which really makes it interesting for your dog or cat to follow! Once the ball is not touched for about thirty seconds, it goes dormant and it will stay like that As long as it's charged until somebody touches it, and then it starts up randomly lighting up and moving around the floor on its own And making a vibration noise. It's a lot of fun to watch the dog chase and play with, and it certainly keeps them entertained for a while! The laughs and fun entertainment are definitely worth it. The only downside is that my dog chewed off the soft fabric covering in about twenty minutes.And she's not a real big chewer. It looks better with the covering on it, but even without it, the ball works fine and she plays with it every day.So that is not a showstopper. But good to supervise your dog for safety.In case they are a chewer, and they decide to destroy the cover. But the ball works fine without the cover too!

Looooves her crazy new ball
Color: Orange, Color: Orange
Our 90lb mastiff/boxer mix Indie is very playful, curious and energetic. She needs toys that engage her and keep her busy. This ball does the job! We’ve had it for less than a week. Here’s what I love and what could be better: PROS: • She dog loves it. She whines for it. She gets absurdly excited when I get it out. She’s a bit of an anxious dog, but had zero problems with it inexplicably coming to life. • It lasts a while on a single charge, so it keeps her busy for a good long time. The longest we’ve used it at a stretch is an hour. • It’s pretty durable. She’s a super chewer (destroyed every “non-destructible” toy we’ve purchased for her), but the actual ball is hard plastic. She gnaws on it and it gets scratches, for sure. But she’s not going to chew it to pieces. • On carpet, it’s reasonably quiet. • It comes with a replaceable silicone button. • It’s easy to charge…just pull off the silicone button and the charging port is inside. • The silicone button is flush with the ball’s hard plastic surface, so there’s no way for her to pull the silicone button out and swallow it or get to the charging port. CONS: • Cover is worthless if your dog is a chewer. It goes on like an envelope with a Velcro closure. We took it off immediately. • Without the cover, it’s very noisy on hardwood floors. To us, it’s worth it. (Though, I work from home, so I might feel differently after the holiday vacation.) • She’s an XL dog, so she can fit the whole ball in her mouth easily and accidentally chomp down on the button and turn the ball off. Not a big deal, just something to know if you’ve got a Lab or larger dog. • With extended playtime, the two halves can come unscrewed, especially with a large dog who uses their paws/jaws on it a lot. Thankfully, it makes a loud buzzing noise when this happens, so we know we need to take it from her and screw it back together. Is this a potential danger? With the rechargeable battery inside, I’d say yes. But we also don’t let her play with this toy without supervision. So keep that in mind. Bottom line: It has its drawbacks, but it keeps her entertained and seems like it should last her at least 6 months with supervised play. Which is honestly REALLY good when we’re talking about Indie, Destroyer of Toys. I’d buy it again.
