You may want to check the heating elements first. Where I live there is a lot of lime in the water that can coat the elements.

You will need an amp meter. I suspect that the lower heating element is out or the thermostat.

Most water heater have a upper and lower element. The bottom is the main work horse.

Take the lower access door off and you can get to the wires to use a clamp on Amp meter. You should get a reading of 10 + amp if it is working. You can check the thermostat with the volt meter also to make sure you are getting voltage to the element . You should have 220 volts across the two wire attached to the element. The elements are not to hard to change. You will need to shut the power Off and the Cold Water off. Drain the tank to get below the bottom element and you will need to get a special wrench to unscrew the old element out of the tank. Hope this Helps

Why does my hot water go hot and cold on my gas hot water service


When water feels cold at tap, check water heater TP valve and drain valve to see if water is hot at top and bottom of heater
Maybe you have bad single-handle faucet cartridge

Another possible cause is bad dip tube

Water only stays hot for about 5 min or


Gas or electric?
Electric water heater ... then test for crossover, check for water leak, replace thermostats, test elements
Gas water heater ... test for crossover, check for water leak

water leak: turn off all taps and put ear against pipe and listen for water leak... check if water meter advances when all water taps are off.

Water won't stay hot long


1) Thermostat may be bad, or out of calibration. Set temperature higher, and/or troubleshoot by type of gas control.

Low water pressure


Hi Bob,

You can determine if the tank is the problem by connecting a garden hose to the drain that is provided on most water heaters. Before doing this, be sure to shut of the electrical supply to the heater - otherwise you can damage heating elements if an electric type or waste fuel by heating an empty tank if a gas / propane fired type.

If you get a slow flow out of this drain, it means that somewhere in the cold water supply side to / in the tank - there is a problem. Inside the tank, the cold water is delivered by a "dip tube" that distributes the cold water to the bottom in the tank. Dip tubes are used in both electric and gas / propane fueled heaters. Here's a cut away view of a typical tank:



6_29_2012_9_57_32_pm.jpg

If the tube is clogged, or there is build up, scale or debris in the supply (cold water) side of the heater, flow rates will suffer. Likewise, if there is a problem with the output of the tank, it will directly affect flow as well.

If you get a good flow rate from the drain, then the issue is going to be on the hot water output side of the heater. Again, the same build up, scale, debris issues on the hot water out put pipe will cause problems with flow. Typcial tanks do not have dip tubes for the hot water side of the tank - as taking hot water from the top of the tank is most desireable and is furthest away from the cold water that rushes in to make up the hot hot water going out.

There's nothing really in the tank itself that can cause issues with flow outside of the dip tube, and piping to and from the tank.

Good luck!

My reliance natural gas water heater overheats causing scalding water to come out of my faucets. I have had authorized service companies come out three times to replace and retrofit different controls and...


Information below is for tank-type electric or gas heater only.

There is a condition called stacking.
This might apply to your water heater or not.
Having authorized service people to your house 3 times suggests more complicated mix of problems.

Stacking is caused when there are repeated short draws of hot water.
As you know, each time any hot water is drawn out of faucet, cold water immediately enters bottom of tank through the dip tube. The dip tube is connected to cold water inlet and runs to bottom of tank.
So all cold water enters bottom of tank close to the gas water heater thermostat.
See illustration of dip tube, that also shows copper thermostat sticking into tank that is connected to gas valve.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html#flushelectric

Let's say your water heater if fully heated and burner is off.
A short draw of hot water causes cold water to enter tank.
Another short draw. And then another short draw, each draw happens close to same time as other draws.
Water at top of tank is plenty hot, but bursts of cold water get near thermostat and cause thermostat to turn on burner.
Burner heats water and more hot water rises to top of tank. Water at top of tank becomes overheated each time stacking occurs.

Again, a stacking situation may not be the cause of your problem.
However, remember if single-handled faucet is opened straight upward, then that draws both hot and cold water. And cold water immediately enters tank.
Only when the single-handled faucet is lifted with the handle all the way to the right, does it draw only cold water. Even so, some single-handled faucets have bleed-over between hot and cold sides, so hot water is drawn anyway.

Another possibility is that the dip tube ends at or near thermostat, instead of going all the way to bottom of tank. The dip tube should go straight down from cold water inlet, but dip tubes are made of plastic, and some self-cleaning tanks have a curved dip tube or dip tube with perforations that create currents designed to stir sediments off bottom of tank (although this is not proven to be effective deterrent to sediment formation).

Water heater heats but not to same temperature


Try shutting off the gas, shut off the water, and drain the tank to remove any sediment that may interfere with heat transfer from the burner. If that doesn't do it, check the dip tube to make sure it is still intact. The dip tube directs incoming cold water to the bottom of the tank and the hot water is tapped from the top of the tank. If neither of those turn out to be the problem, check the thermo-couple. Since a gas water heater typically survives about 6-9 years, you may be better off just replacing it.
