Noticed any of those signs of a failing tempering valve? If so, it's definitely time to get the full and safe functionality of your hot water system checked - and In Deep Plumbing will be more than happy to assist! We're the Gold Coast plumbing specialists in testing, repairing, replacing and installing hot water tempering valves, so get in touch today for a speedy response.

But even with all that legislation in place, the Queensland Building and Construction Commission reports that scalding injuries in bathrooms and showers continue to occur, highlighting the need to urgently detect and address faulty hot water tempering valves.

The shape of arrow in the first schematics represent the pilot operated relief valve and the second one is direct operated relief valve.

As your tempering valve ages, the accuracy of the detection and control of water temperature can suffer - especially if the hot water system isn't a modern one. But while newer valves are better protected with temperature-balancing features, a clear sign that something's amiss is when your warm shower suddenly gives you a blast of really hot water, then it goes a bit cold, then it returns to normal.

The legislation requires those charged with installing hot water systems Gold Coast wide and across Queensland to ensure that a tempering valve is fitted for:

In a nutshell, that's the heart and soul of Queensland's tempering valve legislation - preventing crippling, scarring and agonising hot water injuries. For indoor installations, especially for high-rise living in the Gold Coast, hot water systems are also:

It would be a brave soul to argue against the efficacy and importance of the humble hot water tempering valve. No idea what it is, what it's for, and why the Queensland government cares so much that it's written legislation about it? Read on:

Another thing you do not want to experience is low hot water pressure. Over time, and especially if your system is 5+ years old, hot water tempering valves can get clogged with mineral deposits and other water 'gunk' and contaminants. These relatively inexpensive valves also suffer from wear and corrosion, so a regular inspection is a very good idea. Plus servicing your tempering valve and your system, in general, can prolong the lifespan of your hot water system.

I've come across two different regulator symbols (or so I believe them to be regulator symbols). I'm curious if someone could break down the difference between each.

I believe this symbol represents a pressure regulator. The spring indicates that it is a pressure regulator valve. However, I'm somewhat confused as to what the dashed line is meant to represent. Is it just meant to represent a feedback line for regulation purposes?

This symbol is similar to symbol 1, however, it differs in how the arrow is oriented. What is the significance of the arrow direction?

If your hot water tap is completely turned off and warm water is still dripping out, it might not be the washer - it could be the tempering valve. This crucial component features a ball-type mechanism that can become unseated and ultimately completely dislodged.

However, the responsibility is on the homeowner's shoulders to watch out for the most common signs that they may be dealing with a faulty tempering valve:

The first schematic, the pressure valve is in its normal state, no flow is passing, once the pressure exceeds the pre-defined value, it will change its state to the second schematic. The second schematic also has a pressure indicator, the circle with an arrow inside.

Although we're concerned about scalding-hot water, a major sign of valve failure or problems could actually be a stone-cold shower or bath. If a failing hot water tempering valve is the culprit, the next stream of water could be the dangerous one.

In just about every case, the government requires that hot water systems installed in the Gold Coast and beyond are completed with a temperature control device - which, in practical terms, is a hot water tempering valve. The way it works is simple and yet ingenious: it mixes the hot water with cold water to produce water that won't scald you, your kids and other vulnerable people.
