Sure, “Where is the water shut-off valve?” may not be the first question you ask when you purchase a new home. However, it could prove to be one of the most important questions, considering how much money—and how many headaches—the knowledge could end up saving you if your pipes are leaking.

When water is heated using solar energy, pellet stoves or log heaters for example, high temperatures can occur in the hot water tank. The JRGUMAT thermostatic mixing valve regulates the hot water to the desired temperature.

The temperature of the supplied hot water must be at least 5K above the desired blended water temperature for the JRGUMAT thermostatic mixing valve to function properly. Balanced hydraulic conditions at the hot and cold water inlet are crucial.
As you know, your home is full of plumbing. There are pipes running behind your walls and under your floors that direct water to and from your plumbing accessories, such as faucets, toilets, and bathtubs. Although most, if not all, of your accessories have their own shut-off valves located close to them (such as your water heater’s shut-off valve), there is a way to ensure all the house’s plumbing is turned off at one time. The main valve turns off water to the house, so you don’t need to adjust each accessory individually.
Although the valves are supposed to be visible, a previous owner may not have thought about the shut-off valves for water pipes when they performed DIY renovations. If that’s the case, be sure to have the city’s phone number on hand, so a technician can quickly come turn the water valve off at the street during an emergency.
For advice, please contact your local technical customer services team or representative. We will be happy to advise you on the correct application and installation specifications.

If you still can’t find the main water shut-off valve, it should be listed on your property inspection report from when you purchased the house. Also, builders often place the valves in or around main, ground-level bathrooms, which could mean that it’s not necessarily on an outside wall but could be in a closet near the bathroom.

Excessively hot water can scald the skin. The maximum hot water temperatures at tapping points such as faucets or shower heads should therefore be limited. Because skin damage occurs within minutes at a water temperature of between just 45 and 51°C, within seconds at 51°C and above, and within a split second at over 70°C. In buildings with sensitive uses such as hospitals, care homes, schools and nurseries, but also within in hotels or apartments, the hot water can be set to a safe maximum temperature with the JRGUMAT thermostatic mixing valve.
In addition to understanding how to turn off the water to your house in an emergency, you can also learn more about fixing common toilet problems or what to do if you're dealing with frozen pipes.

The thermostatic mixing valve works without outside energy. When integrated into a circulation system, the amount of hot water needed to cover heat losses is fed back into the storage tank or hot water generator. The rest is fed directly into the mixer.

There are two types of water shut-off valves for typical city dwellings: the outside water shut-off valve controlled by the city and the one that you can control inside the house. The city’s valve is always located on the streetside of your water meter, often near the edge of your yard. Since it is not advisable to tamper with the city’s valve, we’ll only focus on locating your indoor valve.
The JRGUMAT thermostatic mixing valve is also used as a thermal switch, for example in heat exchangers and hygiene storage tanks with different water temperature ranges.

Locating water shut-off valves indoors can be a bit tricky. Hopefully, locating yours is simple, and you can easily find the knob or lever on a border wall. However, if it’s not so easy to locate, you’ll need to play “plumbing detective.” (Note that it won’t be under a sink or next to the water heater.) Your valve is likely in one of these places:
Imagine this scenario: You’ve just walked in from a long day at work only to be greeted with the sound of running water and squishing beneath your feet. You have a burst pipe. And, therefore, you have a big problem on your hands. Rather than let the water continue spewing out and making the damage—and your cost to fix it—worse while you wait for the plumber to come, you’ll want to close your inside main water valve to ensure the water stops flowing.
Whether you're faced with leaky pipes or conducting general repairs, American Home Shield can walk you through how to turn off water to your house.
The JRGUMAT thermostatic mixing valve is an open architecture, proportionally regulating three-way mixer made of gunmetal. The blended water temperature is transferred to the thermostat. This compares the temperature with the set point. If the blended water temperature does not match the set point, the volume in the thermostat changes. This causes the valve slide to move across the pin so that more cold or hot water can flow in as required, until the blended water temperature matches the set point.
Thanks to their high control accuracy, JRGUMAT thermostatic mixing valves can be used for special applications, as regulating elements for maintaining temperatures or for processes requiring a constant water temperature. Wherever hands are not free to individually adjust the water temperature via a mixer tap, blended water set to the desired temperature comes in handy.
Likewise, if you plan to do any remodeling to your home or dive into any plumbing ventures, such as replacing old pipes, you’ll want to make sure to turn off water to the house during the projects. This way, water buildup won’t occur as the result of a burst pipe during demolition or construction.

The housing of the JRGUMAT thermostatic mixing valve is made of low-lead gunmetal. This alloy complies with the current EU lead limits and may be installed without hesitation until 2036 and used afterwards.
