no
try contacting the manufacturer for the part or talk with a plumber supplies shop ( where plumbers get their supplies and parts ) to see if it is available
it will be a sacrificial rod to prevent the tank from corroding out especially around the heating element fittings

Why does the water suddenly runs COLD after many minutes of running hot?


Unless you are using a tankless hot water heater, there is a limited amount of hot water available in the tank. Electric and gas water tanks need time to recover after use, and if you are using heavily, it can exhaust the available supply. That said, there are a couple reasons why you may have less hot water than seems normal. In both electric and gas water heaters, silt can form in the bottom of the tank. This will build up over time and displace water. It also reduces the heating efficiency of gas units. There is a drain valve on the bottom of water heater tanks to allow for purging of this silt periodically, but few ever do it. You could also have, in the case of an electric hot water heater, a bad element or thermostat. Most electric heaters have an upper and lower element and thermostat. If one fails the other will still work, but the water takes longer to get hot and will deplete faster.

My reliance 501 is leaking at both entry hoses ports and also is very hot to the touch near the electrical connection port on the top of the water heater.


Emergency steps:
Turn electric power off.
Release tank pressure by opening bathtub faucet on hot side.
Turn off water supply to heater.
You can turn water heater ON for short periods (1/2 hour) to make some hot water until repairs are made.

It sounds like runaway heating caused by shorted element, possibly caused by leaking water. But I cannot tell for certain what the problem is. Read following links and/or call plumber.
http://waterheatertimer.org/Leaking-water-heater.html
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Over-amping:
Look at watt rating label on side of tank.
For example 4500 watt water heater requires 30 amp breaker and 10 gauge wire.
If you have 20 amp breaker and 12 gauge wire, then change elements to max 3800 watts. Tank will heat more slowly.

You have to fix leaks, and I cannot see that problem. Call plumber or repost question with clear description of leak.

Water heating not heating water


The Emmerson W152 is ordinary 1-year warranty 120Volt electric storage water heater, except with bronze tank. The bronze tank will not rust, and therefore tank does not have anode rod, and tank has 5 year warranty.
http://waterheatertimer.org/pdf/Emmerson-point-of-use-water-heater.pdf
Actions to take:
1) Check circuit breaker.
2) Emmerson plugs into 120V outlet. See if outlet works for other 120Volt light or can opener.
3) Turn off power and do following:
4) Open cover on water heater, and press in reset button.
If reset will not reset, then replace thermostat with ordinary generic thermostat from hardware store.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
5) If reset button is not tripped, test element.
6) Emmerson has 1500 watt element, and correct ohm reading at 120 volts should be around 9.6ohms
http://waterheatertimer.org/How-to-test-water-heater-element.html
7) This element is 7" long, and is also generic, and should be available at hardware, or plumbing supply, or Google-search 'Emerson appliance water heater element.'

Why does my self cleaning gas water heater make clicking noises?


zdriscoll-

All tank water heaters make some amount noise, clicking and "snapping" sounds, particularly after much of the hot water in tank has been used (like after a long shower) and has been replaced by cold water that is being heated vigorously.

If the noises are accompanied by poor or erratic performance, or obviously if something malfunctions, you may require the services of a repair connection.

Hope this helps.

How do i change the element in my water heater


The most important step is to turn the power off. If you still have the manual it is the best to follow the instructions provided in a book.

If not, learn about electric water heaters, how to test the heating elements, how they work and are they OK, than follow the instructions:

Once the power is off, turn the water supply off, attach the hose and drain the water heater.

Unscrew the terminals from the heating element and unbolt the elements from the water heater.

New heating elements has to be with same specs as the old one.

Before turning the water heater on it is VERY IMPORTANT to refill the tank.

Hot water does not last long. Model 82vh40-2 mnf. 05/2005


If the lower heating element burns out the upper element will heat the top part of the tank then shutoff. homw depot/lowes etc should carry elements. 1 turn off breaker, remove element access cover (the 2 panels on the front of the heater) test for electricity at the reset button ( uppermost device in upper panel) to make sure power is off. 2 turn off water (I usually turn off the cold water main to stop water cross feeding into hot supply line back into heater) 3 disconnect the 2 wires on the lower element, test with continuity tester. shhould be no continuity between terminals and tank, but around 10 ohms between the 2 terminals. Check the thermostat for continuity if tank is cold thermostat should be closed ie zero ohms across the 2 terminals.
If stat is bad replace stat; disconnect wires push it up out of the spring clip insert new stat reconnect. If element is bad: drain tank. connect garden hose to tank drain valve, open tank drain valve turn water main on to clear rust sediment and get water flowing. Next remove filter screen from a hot water faucet then turn on ( a hot faucet upstairs or higher than tank drain). Now turn water main off, air will now go in through hot faucet and tank will drain, takes about an hour. Use a water heater element wrench about$10 to remove element(s) make sure no bits of rubber gasket are left in element opening- dig em out with a screwdriver if needed. Insert new element with its gasket and tighten. reconnect wires DO NOT TURN ON ELECTRICITY! BE SURE TO FILL WATER HEATER WITH WATER ! Turn water main back on -air will come out of the hot faucet for several minutes. When water runs without any air sputtering, turn off faucet and replace the faucet filter screen. check element(s) for leaks. turn breaker back on.
