RELIEF VALVE WATER HEATER : WATER HEATER
RELIEF VALVE WATER HEATER : WEIGHT OF BALL VALVES : 22 SOLENOID VALVE.
Relief Valve Water Heater
- A device designed to open if it detects excess temperature or pressure. Commonly found on water heating or steam producing systems.
- safety valve: a valve in a container in which pressure can build up (as a steam boiler); it opens automatically when the pressure reaches a dangerous level
- The relief valve (RV) is a type of valve used to control or limit the pressure in a system or vessel which can build up by a process upset, instrument or equipment failure, or fire.
- a heater and storage tank to supply heated water
- Water heating is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to steam have many uses.
- An appliance for heating water above its ambient temperature, generally for domestic use
Romex clamp, if qualified
CAUTION: Only qualified individuals should be allowed to work with electricity. Do not peform the actions seen and described here unless you are qualified
CAUTION: After you've made all your solder joints and reattached the pressure relief tubing, open your home's water valves and the valve to the tank and allow water to flow. It may take several minutes for your faucets to stop spitting out air, and flow water continuously. Run the faucets on both the hot and cold, until your system is fully charged with fresh water. Failure to do so before re-wiring and turning on your new heater, will void the warranty and cause it to burn out.
Here we are attaching the romex clamp by turning it onto the nut underneath. We do not need to turn the nut, so much as the top portion with the screws, using a pair of channel locks. Performing this, and all work, should be done with the statement "in a neat, and workman-like manner" in mind. Meaning for instance, these screw heads should be facing a logical direction when done, such as perpendicular to a wall, and not such that you need to hold your screwdriver over by the water pipe to get to the screw heads. The same goes when putting in all valves. Take the time to think, and position each piece so that there's neatness and strategy behind it. Another example of this strategy might be how I positioned my shutoff valve to face the opposite way of the pressure relief tube. That way, if something happens and the relief tube is blasting out hot water. I may be able to go to the OPPOSITE side of the tank, to turn off the valve, since that's where I strategically positioned it.
Old pipes cut, not reusing valve
Old water heater after being cut with a tubing cutter, for replacement with the new unit. I believed the valve on this old unit to be bad, so decided not to re-use it. Which by the way, supports the reasoning for shutting the water off in more places than just at this valve! It is also NOT adviseable to re-use a pressure relief valve, since they tend to be corroded with minerals inside that can cause them not to shut off all the way after being operated.
