Hi, W/D here.
Check the breaker. If it is on, trip it to the off position, and back to on. The reason for doing this is that the breaker is a double breaker, and pulls 115 volts from 2 seperate power supplies (busses) in the breaker box to give you 230 volts to your water heater. If your heater is equipped with a service disconnect panel or box in the heater cabinet, or near the heater, make sure that it has been re-energized. Wait about 30 minutes and feel the water outlet line for heat.
If this does not cure your problem, you'll need to trip the breaker/service disconnect back off. Open the connection panel on top of the heater where the wiring enters, and check the connections. Make sure that they are wired correctly, and that the wire nuts are tight, and that the wires are making good contact under the nuts.
Next, open the sheet metal covers that are over the heating elements and thermostat, and check that the wires are connected and tight. Press the red reset button in the center of the plastic shield. If you are familiar with the use of a multi-meter, you can test the power at the terminals. Close up the covers and re-energize the power and check as before for heat.
Best regards, --W/D--

It could be any one of many different problems......You never said what kind of water heater is it gas or electric......In any event it takes awhile for a water heater to heat up 40 gals of cold water. For a gas heater is the gas turned ON did the pilot lite? Is the thermostat set to normal operation and not on vacation. Is the top knob set to on and not pilot. On the Electric heater are the breakers turned ON. Are you getting 220 Volts to the heater. Is the thermostat set right. Hope this helps alittle.......

Can i use my old vent pipe i had for my old 40 gallon water heater


If you are installing new tankless in place of 40 gallon gas water heater, then you CANNOT use same vent pipe.
You must use larger diameter pipe that is specified by instruction sheet, and the pipe must be approved plastic or stainless steel to avoid corrosion.
The vent pipe must also have a condensate trap to catch acidic water that drips back down the vent pipe.
The reason is that tankless burn more gas than regular tank-type heater... because tankless must raise temperature quickly as water passes in a pipe.

Why do we need to have to continuously adjust the temperature of the water when we're taking a shower. We have a new Rheem gas .hot water tank


It *may* not be a problem with the water heater itself necessarily. When you say "keep adjusting the water temperature when you're taking a shower" I presume you're talking about turning the shower hot/cold knob(s) and not the temp thermostat on the water heater itself.
If so, when it starts to run colder, turn the knob all the way to full hot. Is the water then very hot? If so, the water heater is working fine & doing its job, and the problem is likely to be in the shower faucet mixing valve itself. Sometimes a faulty one will expand the inner seals/cartridge as hot water flows thru it, and starts to (wrongly) restrict the hot water flow, thus causing the constant need to "turn the dial up a notch".

My Grohe Aquatower 3000 shower is wonderful BUT after 5 or 6 minutes, the water starts cooling off. Is there some adjustment to keep the water warmer for 10-15 minutes?


You are lucky that your shower is lasting as long as it does. If you have a standard 40 or 50 gallon water heater, mixed with 30% cold water as it comes out, you can expect about 60 gallons of hot water, give or take a little bit. Each of those showerheads on that Aquatower is rated at 2.5 gpm. Even if you are just using the body sprays, you could be using 10 gallons of water EACH MINUTE. There is really only two things you can do, and that is to raise the temperature of your hot water heater by 5-10 degrees so you are mixing more cold water with the hot. The other thing is to buy a bigger hot water heater, or supplement the one you have with another water heater in series.

I have a 40 gallon rheem water heater for a mobil home that is leaking from the top.


If water heater is leaking, then open following 2 links to avoid tank rupture and troubleshoot leak:
http://waterheatertimer.org/Emergency-steps-for-leaking-water-heater.html
http://waterheatertimer.org/Water-heater-is-leaking.html

Open following link if you want to install your own gas water heater:
http://waterheatertimer.org/How-to-install-gas-water-heater.html

40 gallon electric heater at Lowes costs 207, and is easy do-it-yourself using same basic information shown in link above for installing gas heater, except less work.

To have gas water heater installed, can run $2-300 for installation plus cost of heater.
40 gallon natural gas water heater at Lowes starts at $300+, and tanks with longer warranty cost more and last longer.
Trailers require specific type of gas water heater, so be sure to request correct model.

If you maintain the tank: keep chemicals out of same room as gas water heater, attach bare copper ground wire between hot and cold pipes, flush tank each 6 months, clean gas burner each year as shown in manual, read the manual entirely for specific information about your model, and inspect/replace anode rod every 2-3 years then basic 6-year tank can last much longer.

I have a Rheem 40 gal. tank that is leaking water front the top where the vent stack is. It is pouring out. Can it be repaired?


A leaking water heater cannot be repaired, assuming it's the tank leaking and not nearby water pipe.
http://waterheatertimer.org/Water-heater-leaking.html

First thing is to protect your property from catastrophic tank failure where tank ruptures and water runs until it is shut off:
Tanks are under pressure when they are hot.
Close cold water shut-off located above tank.
Turn control knob to 'pilot' so pilot is lit but burner will not turn on.
Open hot side on tub for few moments to relieve tank pressure.

Now your property is safe.
You need a new water heater.
In mean time, gas water heater makes 41 gallons hot water per hour.
Shower used 5-9 gallons hot water.
Bath uses 10-15 gallons hot water.
You can turn on water heater for short stretches and limp by until you get a new heater.

Energy smart hot water heater not giving ample amount of hot water both elements ohm at 12.5


element-connection-450.jpg
For images and product information
For manual


You checked ohms, did you check for 240V across lower element when lower element is turned on?

Energy smart electric water heater
has a control box on top of unit. Water heater does not have typical thermostats that can be tested and replaced. Temperature sensors located above each element send information to control box through small black and red wires. Temperature sensor sells for about $40, but there is no test listed that shows how to determine when sensors fail.

Potential problems:
-Temperature sensor is not reading correct temp
-Control box not processing correct temperature information
-Selector on control box set to 2, 3 or 4
-Thermostat temp on control box set lower than 120 degrees F
-Sediment build-up starting to surround lower element so water doesn't circulate (see if drain valve runs full-open

My Reliance 606 40 gallon water heater only heats up enough hot water to fill a bathtub. We've drained it, the pilot light is fine, it heats up the water really hot, but it just doesn't seem to be able to...


How big is your bathtub? Is your water heater set on the hottest setting? What is the temperature of the hot water at the tap?

Keep in mind that hot water can cause severe burns. Children and those with diminished mental capacity can be seriously harmed by hot water.

The "40 Gallon" rating on the water heater is usually the amount of hot water the unit can produce in one hour. So the tank, and the amount of immediately available hot water, might be smaller than 40 gallons.

My bathtub is 2 feet wide by 1 foot deep and 4 feet long. This is 8 cubic feet or almost 60 gallons. So a 40 gallons of water at 120 degrees, mixed with 20 gallons of cold water (60 degrees), fills the tub with 100 degree water. My January cold water is 42 degrees, so it will take 40 gallons at 129 degrees to fill the tub. If the tub is cold to start it will take even hotter water.

So the water heater might be just fine.

Possible solutions:
1. turn the temperature up on your water heater- or the temperature control could be malfunctioning and not getting the water hot enough.
2. insulate your hot water pipes so that the water loses less heat on the way to the tub.
3. bigger water heater.
4. smaller bathtub, or less full bathtub.
