This may be the case. If you have a check valve installed on the heater to prevent the hot water from backing up into the inlet or cold water side this may happen. A hot water expansion tank at the heater or water hammer devices near the fixture itself should cure the problem.
One question, how high is you water pressure?

    I think you solved your own problem, just by reducing the pressure you should not overcome the spring on your safety relief valve and see any water squirt out. While I'm sure that 105 psi makes for some exhilarating showers, it can cause negative problems in fixtures not designed to handle pressures that high.

    Glad you found a solution.

Is the honeywell wv8840B1109 like a smart meter. I was concerned after they installed this on my new water heater. It's basically an alarm for if the pilot shuts off. Seems awfully big to just be for that....


Thanks for photo link. Not a smart meter.
Just ordinary water heater gas control valve, with small circuit board to support error codes:
Copy following link for handy resources:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent
http://www.thetankatwaterheaterrescue.com/forums/forum3/
http://waterheatertimer.org/How-to-replace-Honeywell-gas-control-valve.html
How the newer gas control valves are different: Old water heater had thermocouple which supplies very tiny current to gas control valve. When pilot light blows out, the thermocouple no longer sends tiny current and gas control valve shuts off gas to heater.
New gas water heaters have thermopile (just like modern furnaces and stoves), which is basically several thermocouples bunched together. So thermopile sends more current to gas control valve, and supplies enough current to power small circuit board. The circuit board records error events and issues simple error codes. If pilot blows out, then thermopile no longer sends current and gas control valve shuts off gas to heater.
Moreover, the new gas control valve can be repaired and replaced without removing from tank. So tank does not have to be drained... saving time and repair cost.

Would high winds and rain cause pilot light on a rannai tankless water heater to go out?


Yes.
High winds can cause reversal of air flow down vent pipe causing pilot flame to blow out.
If situation happens frequently, then special roof cap has to be added.
Have plumber check natural draft up vent pipe.
Other things can cause same problem, for example if vent fan is located in same room as water heater, or house is tightly insulated, and vent fan is ON, then it will draw air down the water heater vent and blow out pilot.

If you'r really lucky you may find a leaking fitting on top of the water heater thats draining down inside the shell and out the bottom, otherwise its time to replace a rusted out water heater.

Brand new unit model G6A-8E. when i first hit the switch it comes on fine and heats water. at a later point (and it seems to be intermittant), when it goes to re-ignite to reheat the water it will not...


Check and adjust igniter probe(s) so that they are in front of the flame good. When you say it goes to re-ignite, can you hear, or see spark happening at igniter, but burner just won't catch?

1992 Reliance electric water heater model 501 has two 4500 watt heating elements , there is no hot water.


Check the breaker and top thermostat and make sure they are not tripped. Move onto replacing elements if above is not the problem.
Turn water and power off to heater and attach a water hose to bottom of heater to drain down tank. May have to open hot side on a facuet to get it to drain.
Once drained remove elements with 1 1/2" found at local hardware stores. once elements removed and new ones in place. Turn water on and get the air out of the system. Once water is flowing from the hot side from all of facuet's in house.
Once all air is out now yaou are resady to turn power onto heater.

When water heater is off a strong gas odor is present. checked by closing or shutting valve control assembly to off positon, where no gas ordor is present.


Hello,
You may have a leaking gas valve control. Make up a squirt bottle of soapy water (use dishwasher soap and water) and spray the On-Off-Pilot knob for leaks, as well as the pilot button. Look for bubbles forming. Also check all the gas line fittings and connectors hooked up to the water heater for leaks. If you are smelling gas, do not attempt to relight the water heater. Close the shut-off valve on the gas line and see if the gas smell goes away. If it does, you may have to replace your gas valve. Depending on the age and condition of your water heater, it may be more cost effective to replace the control or buy a new water heater. Reliance is a common brand sold at stores like Lowe's. Typically, parts like your gas valve will usually only have a 1 year warranty. Check the manufacturer decal on the tank to see what their actual warranty period is. If you find a leak on the gas line itself, you will have to turn the gas off at the natural gas meter before disassembling the line to fix it. Use a soft setting teflon based pipe dope for the pipe threads. If you are uncomfortable doing the work yourself or don't know how to proceed, then call your local gas supplier for help. Douglas
