Hot Water Tempering Valves Installation & Replacement

Hot water tempering valves are compulsory in WA for all new homes and renovations, and when increasing a hot water systems capacity or changing fuel type from electric to gas or vice-versa. Whether your hot water unit is residential or commercial, Plumbdog’s fully qualified and experienced hot water plumbers are licensed to install and replace all makes and models of tempering valve in Western Australia. Whistle and we will come!

What are hot water tempering valves used for?

Tempering valves mix hot with cold water to provide a maximum safe temperature at the hot water tap or shower outlet of no higher than 50 degrees Celsius, and as low as 42 degrees in a child day care centre. The regulated water is normally piped to areas where hot water accidents are most likely to occur, such as the kitchen and bathroom.

If you are experiencing lukewarm water and/or low water pressure, there is a good chance you have a faulty tempering valve, which will need replacing as they are not a serviceable item.

Should I still have a tempering valve installed even if it’s not required by WA law?

Even if you are happy with your existing hot water system, getting a tempering valve installed is always a good idea, as high temperature hot water can cause third-degree burns within seconds of skin contact, especially on children. They are cost-effective and easy to install in most residences and businesses, and are a good insurance policy against hot water-related burn injury.

This is the second time we've used Richard and again, the service was excellent. He is quick, efficient, made great recommendations and tidied up. We now have a great in-tap water filter system that doesn't take up much space and a sleek modern looking tap. Thanks again for a great job Richard.

We called on Rich to locate a leaking pipe underneath a concrete house slab. Using his thermal and audio detection equipment, he was able to locate the leak in the middle of the house to within 50mm and then expose the corroded pipe and repair with a minimum of damage to the floor. We were impressed with Rich's methodical approach in locating the leak which definitely saved time and unnecessary repairs.

Top notch service and advice from Richard, who clearly takes great pride in his work. He serviced my toilet and replaced my hot water system. For each job, he made it clear what needed to be done and what my options were, and then set about getting things done without fuss. I can't recommend Plumbdog highly enough!
