The problem with keeping your storage hot water at this temperature is that at 60℃ hot water can cause severe scalding in only a few seconds. Small children, the elderly, and the infirm are some of the groups at most risk of burns.

Both valves contain a temperature-sensitive element which expands or contracts in response to temperature changes in the incoming water. This expansion and contraction control a slide valve which allows more or less hot or cold water into the mix to consistently maintain the desired temperature.

A tempering valve is accurate to around 3℃ +/-, while a thermostatic mixing valve can keep the water to 1℃ +/- and responds faster than a tempering valve to changes in incoming water temperature.

A large tourist attraction in Melbourne was totally shut down due to a Legionnaires disease outbreak caused by bacteria breeding in the building’s air conditioner cooling tower system. This is just one example of many and is why we should take the risk seriously in our homes.

Drainage is important because it helps to prevent water damage. When water doesn’t drain properly, it can lead to all sorts of problems, from flooding to structural damage. The advantages of drainage are maintained by a drainage system, which also keeps particles and dirt out of your base and prevents water from coming back into your home and foundation. If you live in a region where you can anticipate receiving a lot of rain throughout the year, it is also essential to have a water drain in place.

Solution - install a tempering valve or TMV to the hot water pipe supplying personal hygiene areas (bathrooms), in some situations the whole house, which reduces the water to a much safer 50℃ (122℉), or in some cases 45℃ (113℉), to safeguard residents.

Not sure if you need to install a tempering valve or a thermostatic mixing valve? Your local plumber can provide you with advice specific to your water heating requirements but here’s the low down to get you started.

It’s especially important to fit a solar hot water system with a tempering valve because of the higher temperatures the water can be heated to on hot sunny days.

TMVs are often more expensive to install, however, can be repaired and maintained lasting longer on average than a tempering valve. The Australian Standard states that tempering valve testing should be carried out every 12 months with thermostats and o-rings replaced every 5 years.

Prohibiting the growth of bacteria in your hot water system is achieved by maintaining the thermostat at 60℃ (140℉) or above. However, increasing the temperate significantly above this will just result in higher power bills, not added protection.

No matter what type of property you own, it’s important to know the basics of drainage. Inadequate water drainage can result in a variety of issues, including structural damage and flooding. In this post, we will discuss the three types of drainage: surface drainage, subsurface drainage, and stormwater management.

Australian plumbing regulations state that all hot water systems in new homes must be fitted with a tempering valve to control the hot water supply to the bathrooms. Our plumbers recommend installing a valve on all storage hot water systems, new and old.

Stormwater management is a type of drainage that is designed to control runoff from storms. It involves using techniques such as detention ponds and infiltration basins to store water and allow it to percolate into the ground slowly. Stormwater management is often used in areas with high rainfall or flooding potential.

Surface drainage is the most common type of drainage. It involves directing water away from buildings and other structures, using gutters, downspouts, and drains. Surface drains are typically located at the base of a slope or near a body of water. They collect runoff from rainfall and snowmelt, and direct it away from the property.

Tempering valves are usually installed in standard home water heating situations. A thermostatic mixing valve would be fitted if there was a requirement for more exacting control of the water temperature, as well as in larger applications.

The large volume of water which spends most of the day just sitting in your hot water tank (unless you have instant) is a perfect breeding ground for all sorts of nasty bacteria. One of which is the Legionella bacteria that can cause a serious pneumonia-like bacterial infection Legionnaires disease, which in some cases leads to death.

Often tempering valves and TMVs can also restrict the supply of hot water totally if for some reason the cold water stops, further safeguarding against burns.

Subsurface drainage is used to collect and remove water that has already soaked into the ground. This type of drainage is often used in areas with high groundwater tables or poor soils. It can also be used to prevent foundation damage from excessive moisture. Subsurface drains are typically located around the perimeter of a property, and are connected to a drainage system that directs the water away from the property.
