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.

BEST MAKEUP EVERRRR!!!
Size: 1.8 Fl Oz (Pack of 1), Color: Original
Love this! Blends into natural skin color so well. Coverage is great without looking cakey or like heavy makeup but evens out skin tone and lasts all day. Doesn’t dry my skin. I’m 50+ and don’t even use moisturizer before applying. Apply with fingers and use a brush with powder and again, lasts all day! I don’t use anything else. However I do NOT like their color sciencepowder. It’s horrible. But I love the Younique pressed powder with it. Bought on a whim to get spf and so glad I did. Tried It brand and some others and none compares!

Almost a home run
Size: 1.8 Fl Oz (Pack of 1), Color: Original
Initially I really loved how this sunscreen made my skin look. The tint provided enough coverage to even my skin tone and hide my remaining melasma. It gives a very nice glow that doesn’t look too greasy. I have dry skin, and this was moisturizing enough for summer; although I would probably need a moisturizer first in winter. After using this product for many weeks however, I realized that it leaves residue on my hair making it feel chalky and dry. I’ve tried different techniques of washing my hands really well after so I don’t spread residue to my hair when I fix it, but I found it still made it’s way into my bangs. I even tried pulling my hair back and wait an hour before putting it down but inevitably my hair got this dirty chalky feel to it. It makes me feel dirty which is enough to deter me from wanting to use it exclusively. I wanted to use a tinted physical sunscreen to stop the pigmentation to my melasma, but I just prefer how chemical sunscreens feel. I started to use this over my cheekbones after I apply my chemical sunscreen to help deflect blue light, but I think going forward I’ll just purchase a more affordable option if it is going to be used on such a small area.

Great option for a natural finished look
Size: 1.8 Fl Oz (Pack of 1), Color: Original, Size: 1.8 Fl Oz (Pack of 1), Color: Original
I have been using Colorscience Total Protection Face Shield SPF 50 Original color for over 5 years. I love that the color blends with your skin so well and provides a natural looking finish. It does not cover all of my dark spots or defects, but it makes my natural skin look better. The finish is soft and silky and the 50 helps protect my skin from additional sun damage. If you are looking for a more natural finish, this is a great choice.
