Buy a pressure gauge at hardware store that screws onto hose connection.

Test pressure on outdoor spigot.
Test pressure on water heater drain valve.
This will tell you if the pressure problem is before -or- after the water heater.

If problem is before the water heater, then the shut-off valve located on cold water line is suspect.
If problem is after water heater, it could be in the hot water outflow pipe on top of water heater, or a nearby elbow.

Can I install a 19 gallon hot water tank to a 120 volt breaker?


Anon, It would only work if that was meant to be hooked up that way. Check the specifications in the manual or the plate on the heater itself. Check the attached links,instruction and guides, 1st link shows typical wire hook up on both 120 and 240 v. Good luck .

My electric hot water isnt workin! My unit is 10 years old GE10074 240 volts AC only-45 gallons. 4500 WATTS. The cold water runs fine-NO HOT-what could it be.GE model#:GE38S06AAG Serial#305D10074


Hi LiLo

Is this unit designed to pre heat the water to a given temperature or is it On-Demand. Eg the heater turns on only when a tap is turned on?
Either way, you need to check if AC is getting to the heater by using a multimeter of a Neon Light tester.
Once you find out if it's got AC at the heater then it's a simple matter of following the AC to the actual element.
If the Element shows 240v across the element but does not heat up then the Element is open circuit and will need replacing.
If there is some control mechanism stopping the element from getting 240v then you've found the problem. The Control circuit or temperature sensor.


Good Luck

How do you winterize Model GE20P06SAG? There is no drain at the very bottom...?


Thank you for including model number for EZ identification of water heater
To drain tank without drain valve: Remove TP valve at top of tank and siphon out the water. Then reinstall with correct pipe configuration shown in product manual.

Product manual shows drain valve is not supplied with this unit.
http://waterheatertimer.org/pdf/GE20P06SAG-under-counter.pdf

Product manual shows the Installer should add both shut off valve and drain valve on cold water inlet line.

Where is the combustion shutoff system on a Rheem 30 gal moble home hot water heater


Disproportionate number of water heater problems are Rheem-related, yet Rheem is just 1 of 3 major water heater manufacturers.

If you have Rheem tank-type gas water heater, and the combustion shut off has tripped the FV system, then there is a broken glass vial located under the burner.
Rheem does not post service manuals, and they may or may not send the glass vial for replacement. Depending on model which appears on label on side of tank. Year of manufacture are 3rd and 4th digits in serial number.
And they may want you to contact a qualified service technician (plumber)
You will have to replace glass vial, and clean the arrestor screen and clean the combustion parts, check gas pressure, and check venting.
Other companies post service manuals and do not rely on the glass vial.

Rheem warrior glass serial num r0296b08705 model


You need to first determine if the burners light or not.

As long as the unit wasn't run with a dry tank the unit should not have been affected by continuous water running, unless it got hot enough to damage the thermocoupler which is an easy replacement. That is the part that your pilot/ignitor warms so that the gas valve will open the gas line to the burners.

Can i replace 4500watt elements with 5500watt on a 606 model


1) Manufacturer's warranty will be voided, and I've never seen recommendation that suggests better heating or saving money from replacing 4500W with different wattage element.

2) That being said, you have 240V water heater.
4500Watts divided by 240 = 18.75 amps
5500Watts divided by 240 = 23 amps

20 amp circuit breaker with 12 gauge wire is rated for 80% of load = 16amps
30 amp circuit breaker with 10 gauge wire is rated for 80% of load = 24amps.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html

3) You can use 5500Watt element if you have 30 amp breaker and 10 gauge wire.

The water won't get hot on model 81v52s 50 gallon. is there a rest or how to diagnose.


The reset button is located behind top panel on water heater.

If you have some hot water, then reset is not tripped, and tank has different problem.

I suggest a complete 30-minute troubleshoot using multi-meter from hardware or home center.
When test calls for checking voltage, rotate multimeter dial to 240-250-277 VAC
When test calls for continuity or testing elements, rotate multimeter dial to Ohms
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html

Follow troubleshooting steps from top of page to bottom, and water heater if fully repairable by homeowner.
See label on side of tank for wattage of element.
Second two digits on Rheem serial number are year of manufacture.
Shown below are Rheem 4500 Watt element and Generic upper thermostat.

Rheem warrior glass serial num-rh1098154699 model num-71-40d b That is all the information i collected off my hot water heater we have no hot water at all and i dont know how to fix this problem...


The label would also say if water heater is gas of electric.
That would be helpful information that could lead to troubleshooting.
Serial number tells us water heater was made on Nov 1998, which tells us the manual will not be on the Rheem website.

So if you have electric water heater, and no hot water.
There can be 4 causes.
1) Circuit breaker is not delivering 240 to water heater. Test top two screws on upper thermostat to see if tank has 240V.
2) ECO red reset button is tripped. Open top cover on tank and push reset button.
3) Upper thermostat is bad. Replace thermostat.
