When there's a sudden reduction in water pressure due to high water demand or a pipe failure elsewhere, the dirty water flowing out from sinks, drainage systems, and toilets can be sucked back into the water system and mixed with your clean water. Your RPZ valves use a differentiated pressure system to keep the backflow from entering potable water. In Illinois, RPZ valves are required to be installed in any building along with fire prevention systems, irrigation systems, or large boilers. If you have any of these things in your building, you have RPZ valves installed on your water pipes.

Plumbing problems are bad, but they become even worse when they pose a danger to your health and the health of people in your apartment, school, or business. The reduced pressure zone (RPZ) valves in your plumbing systems stand between you and illnesses caused by contaminated water. If these valves aren’t working properly, you’ll want to know right away so you can call your plumber and get an immediate repair. Here are the details on what an RPZ valve is, signs that your RPZ valves need attention, and what you can do to prevent future issues with your RPZ valves.

If you have problems with a TMV, then you sometimes see outward signs that all isn’t well. For example, water might seep out of parts of the valve; you may even see some water on the floor under it. This might indicate a faulty seal or a corrosion problem.

Changes in water temperature have various causes. For example, the valve may be blocked or may have moved out of position. The thermostatic element might have stopped working or might have a problematic O-ring. Or, you might have a problem with water pressure or flow through the valve.

Maintenance is the most important thing you can do for your RPZ valves and your whole plumbing system. Regular plumbing checks will catch any developing issues in the valves before they fail and allow your water supply to be contaminated by backflow. Make sure to set up regular maintenance with your plumber.

A whole host of things cause plumbing leakage, from rust to thermal expansion to changes in water pressure. An RPZ valve will not always leak when it needs repair, but a leak is still the most common sign of a problem with the valve. If you see water flowing out of the relief valve, this may mean that the two check valves have failed, which indicates that it's time to replace the whole RPZ system on that pipe. It could also suggest that there's debris caught in one of the check valves, which calls for a valve cleaning.

Slow water flow can have many causes other than a bad RPZ valve, like high water demand or a poor water supply system. However, if you're experiencing consistent bad flow or your water is taking forever to drain, it's time to get those RPZ valves looked into. The slow water may be due to a pressure buildup in the valve, which will delay your water supply. An experienced plumber will be able to fix this problem for you.

First, it allows your system to store water at a high enough temperature to keep bacteria at bay. However, it also regulates the temperature of the water that you use.

An RPZ valve keeps the dirty water or waste in your pipes from flowing backward and contaminating your clean water supply. RPZ stands for reduced pressure zone, which refers to the fact that RPZ valves use the force of reduced pressure to keep dirty water flowing in the same direction. Although it isn't the only kind of backflow preventer, an RPZ valve is a more secure device than a single or double-check valve, which are other kinds of backflow preventers. This is because The RPZ valve has an extra relief valve.

A thermostatic mixing valve (TMV) bridges the hot water in your system and the water that comes out of taps or showers. It keeps your hot water system safe in a couple of ways, and can keep you safe, making it a crucial part of your home plumbing that your local plumber should always check.

Sometimes, the first sign of a TMV problem is a change in the way your water comes out of a tap. Typically, you see a reduction in flow or pressure here.

However, excess heat isn’t the only sign of trouble here. Sometimes, a failing TMV makes the water too cold. Or, water may not run at the right temperature consistently. It may fluctuate between being hot and cold.

When you turn on a tap or shower that connects to a TMV set-up, then the valve controls the release of hot water. Typically, it mixes hot and cold water together to reach a set temperature as dictated by its thermostat setting set by a plumber with a TMV licence. So, your water should never run so hot that it could scald or burnWhen all is well, the TMV works seamlessly. However, it might develop problems that prevent it from working as it should. What are the signs that your valve has a fault?

This is usually a part of regular maintenance, but it deserves a special mention because of the annual testing that water companies are required to carry out on RPZ valves in Illinois. The law demands that RPZ valves be tested by a certified tester when they are first installed and at least once a year after installation and that up-to-date records of the tests are kept on the site.

Again, these problems can have various causes. Sometimes, water can’t run through a TMV freely because parts of its valves are gummed up with debris or scale. Older valves might also suffer from corrosion which blocks them up. Or, a valve might not have been fitted correctly in the first place.

In some cases, a faulty TMV can also affect your cold tap. Here, you might find that this tap runs warm or hot rather than cold.

For example, your water might start to run sluggishly and slowly all the time. You might struggle to get the tap to give out more than a trickle of water. Or, your water might switch between working normally and running at a reduced pressure or flow.

If a TMV valve stops working correctly, then you may notice that your hot water suddenly starts to run hotter than it should. If the valve can’t regulate temperature correctly, it might not be able to cool hot water down enough to make it safe.

If your water is cloudy or discolored, smells or tastes bad, or has little particles swimming around in it, it's definitely time to call a plumber. When this happens, it usually means that one of your RPZ valves has failed completely and that a backflow has made it into your clean water supply. Bad water qualifies as an emergency, so you shouldn't delay the fix. If anyone has drunk the contaminated water, you should watch them for signs of dysentery, salmonella, and other waterborne illnesses.

So, get a certified tester into your building or business every year to look at your RPZ valves and check off those certificates. Not only will this keep your building on the right side of the law, but it will also protect you and the other people in the building from contaminated water caused by a valve failure.
