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.

OK, that warning label is telling you that the valve is protecting the appliance from both over-heating and over-pressure (combination). The part about removal from point of installation is a warning that relocating it to another part of the system will not provide adequate protection (back in the day they sometimes located a pressure-relief valve on a pipe outside the home). You can remove and replace it. Pull off that plastic cover so you can see the threaded part. Get a bigger wrench, at the factory they use a pipe compound that sets hard. Your tank is iron and unlikely to be damaged

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.

JRGUMAT 3400 thermostatic mixing valves are currently available with factory-set standard temperatures (25/40/48/55°C). The individual settings range from a minimum of 20°C to a maximum of 65°C. Other types covering additional temperature ranges are available. It is possible to change the blended water temperature setting within the specified setting ranges of the respective thermostatic mixing valve.

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. Click here for more information on the conversion of the product range to lead-free materials.

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.

First, try to tighten the relief valve to break the hold of the dope and threads. It should be easier to tighten than to remove. You only have to move it a little to break the thread hold . Then remove the safety valve with a bigger wrench, say an 18" or 24" crescent wrench. The tightening is easier since the strain on the threads is in the direction of tightening.

I have the below T&P valve, I'm not able to remove it to replace a new one. I saw there has some declaration above the valve which said it's the combination of the water heater, does this mean I can't remove it? If no, how to remove a very tight valve. Thanks a lot.

Superlok relief valves open at precise pressures to regulate fluid of gas pressure flawlessly. Adjustable between 10-225 PSI.

If the TP valve is bad, you have to replace it, even if it's risks damage to the threads. I had the same problem and borrowed a long pipe wrench to get it off. You can try to break it free a few ways:

Thermostatic mixing valvetemperature setting

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.

·The JRGUMAT can protect against scalding where set to do so. The high control accuracy also ensures safety in production processes with defined temperature specifications.

•Connects to copper, CPVC, PEX, LPDE, MPDE, HDPE and polybutylene tubing; •Easy to install no tools or tube inserts required connections ...

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.

With the JRGUMAT thermostatic mixing valve from GF Piping Systems, mixed water with a constant temperature can be ensured in an energy-efficient manner - wherever this is desired or required. It is used in different system sizes and applications. The JRGUMAT thermostatic mixing valve is extremely durable and has proven its worth for decades.

On farms, for example, the JRGUMAT thermostatic mixing valve regulates the water temperature of drinking troughs for livestock or during feed preparation.

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.

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.
