WattsTempering Valve

The mixing valve is a sliding component that is contained within the tempering valve, ensuring the correct ratio of hot to cold water is being let through, and a tempering valve usually controls the temperature within ±3%. This video explains the workings of a tempering valve:

A pressure reducing valve operates through a pressure reducing pilot that senses and adjusts to downstream pressure. The pilot commands the valve to adjust—throttling or closing when pressure exceeds a set point and opening when it falls below, ensuring consistent output regardless of external changes.

The way that a tempering valve works is not as complex as it may appear. A tempering valve contains a temperature-sensitive element, whose job is to focus on adjusting the mix of hot/cold water depending on:

‍Tempering valves and TMVs (thermostatic mixing valves) get mixed up regularly, and they do have some similarities due to the fact they both mix hot/cold water together, but the main differences between the two are :

In Queensland, hot water must be heated to a minimum of 60°C to prevent the growth of bacteria such as Legionella, and a tempering device ensures that hot water is delivered to taps at a maximum temperature of 50°C.

When you think about it, many of us really do take hot water for granted. We turn on our hot water tap and water at the correct temperature is released from the faucet almost every time and when it’s not, we are pretty annoyed about it… just think about when cold water comes out of the showerhead when you turn on the hot tap.

A tempering valve, otherwise known as hot water mixing valve or a hot water tempering valve, is either a 2-inlet or 3-inlet adjustable mixing valve which is activated by temperature. It regulates the temperature that hot water is released from outlets throughout your home, by mixing both hot and cold water together to achieve a particular temperature.

One of the little additions to ensure that the water being used in your home is at the correct temperature at all times is a tempering valve. If you haven’t heard of them before, or aren’t sure how they work, you are not alone!

The choice of PRV depends on the specific needs of the application—considering factors like flow patterns, pipe characteristics, and system demands. Options vary from full bore designs for minimal pressure loss to specialized models designed to handle low flows or reduce cavitation.

We specialise in providing professional maintenance plumbing services – 24 hours a day, 7 days a week everywhere in Brisbane. If you have an emergency plumbing situation then contact our office and we will come to you ASAP!

PRVs can be mechanical, electronic, or hydraulic. Bermad specialises in fully automatic hydraulic PRVs, which are particularly efficient in managing variable flows and pressures.

Municipal Systems: PRVs are crucial at the start of pressure zones or DMAs (District Metering Areas) to protect downstream equipment and household plumbing while ensuring reliable pressure for users. Irrigation: In agriculture, PRVs manage the water pressure for drip systems, pivot irrigation machines, and lower elevation fields to prevent damage and ensure efficient water distribution. High-Rise Buildings: Installed on each floor or every few floors, PRVs safeguard internal plumbing and fittings from excessive pressure, promoting longevity and safety.

If you have any further questions regarding tempering valves or would like to arrange for one of our qualified Brisbane plumbers to check a tempering valve in your home, give Brisbane Plumbing and Drainage a call on 1300 616 203 and we can help. ‍

A Pressure Reducing Valve (PRV) is a type of valve that reduces a higher upstream pressure to a stable lower downstream pressure, irrespective of fluctuating demand or changing upstream pressure. These are essential in various settings, from municipal networks to high-rise buildings, ensuring protection against overpressure and maintaining sufficient pressure for effective use.

Water from city mains tends to be at high pressure, and can often fluctuate. Pressure reducing valves (PRV) reduce water pressure to a more suitable level, and help to regulate the pressure regardless of any fluctuations. See Bermad’s pressure reducing valves below.
