Temperature and Pressure Relief Valve

WARNING

Explosion Hazard

If the temperature and pressure relief valve is dripping or leaking, have a qualified person replace it.

Examples of a qualified person include:￿ licensed plumbers, authorized gas company personnel, and authorized service personnel.

Do not plug valve. Do not remove valve.

Failure to follow these instructions can result in death, or explosion.

For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening marked “T & P RELIEF VALVE” (see Figure 15A). This valve must be design certified by

a nationally recognized testing laboratory that maintains periodic inspection of the production of listed equipment or materials as meeting the requirements for Relief Valves and Automatic Shut-off Devices for Hot Water Supply Systems, ANSI Z21.22. The function of the temperature and pressure relief valve is to discharge water in large quantities in the event of excessive temperature or pressure developing

in the water heater. The valve’s relief pressure must not exceed the working pressure of the water heater as stated on the data plate.

IMPORTANT: Only a new temperature and pressure relief valve should be used with your water heater. Do not use an old or existing valve as it may be damaged or not adequate for the working pressure of the new water heater. Do not place any valve between the relief valve and the tank.

The Temperature & Pressure Relief Valve:

•Must not be in contact with any electrical part.

•Must be connected to an adequate discharge line.

•Must not be rated higher than the working pressure shown on the data plate of the water heater.

The Discharge Line:

•Must not be smaller than the pipe size of the relief valve or have any reducing coupling installed in the discharge line.

•Must not be capped, blocked, plugged or contain any valve between the relief valve and the end of the dis- charge line.

•Must terminate a maximum of six inches above a floor drain or external to the building.

•Must be capable of withstanding 250°F (121°C) without distortion.

•Must be installed to allow complete drainage of both the valve and discharge line.

T&P Relief Valve and Pipe Insulation (Some Models)

1.Locate the T&P Relief Valve on the water heater.

2.Locate the slit running the length of the insulation.

3Spread this slit open and slip it over the T&P Relief Valve. See Figure 15B. Apply gentle pressure to the insulation to ensure it is fully seated on the T&P Relief Valve. Once sealed secure the insulation with a section of tape. IMPORTANT: The insulation or tape should not block or cover the T&P Relief Valve drain opening. Also the insulation or tape should not block or hinder access to the T&P Relief Valve manual relief lever.

4.Next locate the hot water (outlet) & cold water (inlet) pipes to the water heater.

5.Select one of the sections of pipe insulation and locate the slit that runs the length of the insulation.

6.Spread the slit open at the base of the insulation and slip it over the cold water (inlet) pipe. Apply gentle pressure along the length of the insulation to ensure it is fully seated around the cold water pipe. Also ensure that the base of insulation is flush with the water heater. Once seated, secure the insulation with a section of tape.

7.Repeat steps 5 through 6 for the hot water (outlet) pipe.

Its construction typically includes high-quality materials that resist wear and corrosion, contributing to a longer lifespan and dependable operation.

The W10100910 part often refers to the dryer thermal fuse, a critical safety component that prevents overheating. When the dryer temperature exceeds safe levels, this fuse blows to cut off power, protecting the appliance and the surrounding area from potential fires. The reliable operation of this fuse is essential for maintaining safety standards in the home and extending the life of the dryer.

Both parts feature user-friendly designs, allowing for straightforward installation. Usually, homeowners or technicians can easily replace them without needing extensive tools or specialized training. This accessibility makes it convenient for individuals looking to perform DIY repairs, ultimately saving time and money on professional service.

In terms of technology, these components highlight Whirlpool's commitment to innovation and quality. For instance, the water inlet valve is engineered to accommodate variable water pressures, ensuring consistent performance even in different home plumbing situations. The thermal fuse utilizes advanced material engineering to ensure rapid response to temperature increases, enhancing the safety protocols of modern dryers.

Overall, the Whirlpool 315420-000 and W10100910 are excellent representations of the brand’s dedication to customer satisfaction and appliance longevity. Their main features focus on reliability, ease of installation, and safety, making them essential components for maintaining optimal performance in Whirlpool washing machines and dryers.
