There is a lot of controversy over this. The reasons that you may want to do it are because of cathodic erosion. If the water has high mineral content it can shorten the life of the tank. If you are using plastic pipe in the house it can affect the situation also. All that aside, the reason for the grounding is found in the National Electrical Code and is in section 250.140 . The reason is that the code calls for grounding of all other metal piping systems that do not carry water. That would mean the natural gas line! The reasoning is because if something happens and energizes the gas line and it is not grounded it could cause a fire or an electrocution hazard. The code calls for a ground wire of sufficient size to handle a stray voltage of the amount that would be most likely found in the application. So you have 220 VAC in most residential applications. That would mean that you should use something in the neighborhood of about # 8 to # 12 AWG as a ground. There are charts to determine the exact size. IT depends on the length of the run.. The wire should be connected to the area closest to the control head if the head is not insulated from the pipe and then run to an electrical ground nearby. The installation has to be done by an electrician and not a plumber unless you do it yourself IF YOU ARE THE OWNER OF THE HOUSE AND IT IS NOT A RENTAL.

Should ele and gas work to gether onwater heate .dont now if we used water or gas.or bouth


Some RV water heaters are both gas and electric, depending on what hookup is available at campground.
Otherwise, water heaters are electric or gas.

Gas water heaters have a 3" to 4" round vent pipe located on top.
Electric water heaters have electric wire connected on top or side of heater, but no vent pipe.

We have a reliance sta kleen 805 lp water heater that we installed used and it will not let us go through the start up procedure. i assume its in some kind of lock out mode, it does not respond to hot...


Used, Reliance 805 is power vent gas
10 year old water heater that is newly installed.
Unknown gas control valve.
I'm not a fan of installing old power vent water heaters.
Usually these things are so expensive that old one is only replaced when it fails.

120Volt Outlet must have correct polarity and unit must be grounded between ground prong on cord to manifold tube connected to bottom of gas control valve. Test for continuity with multimeter.

Is this an early FV model with air intake located on bottom?
If air intake is clogged with dust, then combustion chamber overheated and tripped FV system. The older heaters need replacement parts and new gas control valve, or entire heater must be replaced.

Replace gas control valve.

AO Smith Water heater FPSH50-260 keeps blowing fuses


FPSH series is a power vented residential gas water heater.

1) The blower is plugged into 120Volt outlet. If blower has short, then it will trip breaker.
Blower could be Fasco model 7021-10195, or 7021-10770. Call AO Smith: 1-800-527-1953. They will need model number and serial number located on label on side of tank.

2) Before calling AO Smith, check outlet with circuit analyzer. Outlet must have correct polarity and must be grounded. Unplug cord to water heater and run continuity test from ground prong on electrical plug to manifold tube on gas valve.

3) Also if a fluorescent light fixture is on the same breaker, that can cause burner to short cycle.

4) Connect water heater to different outlet and see if problem continues.

5) AO SmIth has service manuals for the FPSH series that download to your computer:

High water in basement, the push button temp indicator reads both leds lite on both ends. i dont know who to reset


1) Call service technician.

2) If water heater flooded, contact insurance company for possible replacement coverage.

3) Manufacturer's suggest replacement of any flooded water heater.

4) Be very careful around wet or previously wet water heater.
Insulation inside tank will stay wet. Household electricity is grounded to water pipes that are connected to gas or electric water heater. Touching wet water heater can be fatal.

5) Read label on side of tank for product identification.
Read manual for possible part replacement.

1) Electric heater, do not touch electric heater that is wet or has been wet unless power is 100% off.
2) Gas heater: Same applies to gas heater if controls are electronic, or if electric is grounded to hot water pipe.

3) Manufactures suggest replacing water heater that has been flooded.
Warranty is voided.
Set next heater higher.
http://waterheatertimer.org/How-to-install-gas-water-heater.html

4) Electric: You can replace thermostats and elements, but if insulation is wet, the unit could short and be continual electrocution danger >>> and you can't operate electric heater with covers removed because cool air will keep thermostats from reading correct temperature.
5) Gas: You can clean out combustion chamber and replace gas valve and burner assembly, but new heater from local hardware or box store will save time and possibly money.

6) Use old heater as tempering tank if incoming water is cold:

It is the same as all the other appliances in your house, they should be earthed (grounded). You can run a new earth wire from the meterbox to the hot water heater or pick up an earth anywhere in the house and run it to the heater. The earthing conductor connecting to the hot water heater should be the same size as the active and neutral conductors or no less than 2.5mm square.

Rheem water heater model #82V661 serial # RH0106D11663 leaking water at lower panel. Water is coming from above wiring and control panel. Is this fixable or need to be replaced? Mfg date is 01/2006


You have 240volt electric water heater
Check both elements for leaking.
Check top of tank for leaking pipes.

If water heater is leaking from side of tank, then tank is rusted out and could rupture.
This tank must be replaced.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html

My friend welded his tank to get more life out of tank, but he assumed the risk.

Hot water heaters are under pressure from heated water which expands.
If tank ruptures, water will flood out of tank and water will run until shut-off is turned OFF.
This causes major damage inside home.

Protect yourself first, and then let's talk more.
1) Turn off water at shut off located on cold water line above tank.
2) Turn off power to water heater:
Gas heater, rotate valve to 'pilot' so pilot is lit but burner does not turn ON.
Electric heater, turn off circuit breaker.
3) Open tub spout on hot side and let run a bit to relieve pressure.
4) Now your property is safe.

You can limp along with failed heater if leak is slow.
Turn heater ON when you need hot water.
Typical Gas heater makes 41 gallons hot water per hour.
Typical Electric heater makes 21 gallons hot water.
Shower uses 5-9 gallons hot water, bath uses 12-14 gallons hot water.
http://waterheatertimer.org/images/Water-heater-reference-guide-2.jpg

If you are going to install heater yourself:
Look at label on side of old tank to identify size and particulars.
I buy ordinary heaters from Lowes and Home Depot and always buy scratch-n-dent models when possible, because superficial damage to outer tank does not lower lifespan of heaters I have installed.
Buy same size heater if it worked fine before.
Buy new flexible water connectors.
Set water heater in drip pan.
Offer 10% less than price shown. Make them deal with you. Shop Ace hardware, Lowes, Home Depot. Kick the tires since you have a bit of time.

I know you have electric heater, but many folks read these answers, so I include info on gas too.
#1 rule) tankless heaters are a rich-man's toy, because tankless will never pay you back, and will become major money pit if you encounter 1 repair. Electric tankless heaters require larger electric service box. Gas tankless require larger gas line (larger gas line, more gas consumption, bigger bill unless you cut consumption)
2) How to install gas heater:
http://waterheatertimer.org/How-to-replace-gas-water-heater.html
3) How to install electric heater:
Read link above because many of same steps apply to electric.
The difference with electric, is turn off power, disconnect wires, and reconnect wires exactly like before. Set electric heater directly on insulated surface like dense blue styrafoam. Cut styrafoam in circle so it fits inside dip pan. Wrap entire electric heater with insulation blanket, except don't cover TP valve.
4) Connect bare copper jumper wire between hot and cold pipes to prevent stray current corrosion which will shorten life of tank. Make sure cold water line is grounded.

It sounds like you need to replace it, Actual cost can very widrly depending on your location but I would say $350-400 is probably close. Plus installation unless you can do it yourself. Hope this helps. Thanks
