Question about Rheem 40 Gallon FVR NATGAS Low WATER HEATER 6YR 22V40SF

1 Answer

Rheemglas Low Pressure Gas has Dirty Water

We are experiencing dirty water coming out of our hot water cylinder, which was installed new in 1990. It is starting to clog our tap mixers. After flushing it, it contains many flakes of dirt, or is it rust?

Does this mean that the inside of the cylinder is starting to rust. Is this the end?

You've done well with having a water heater lasting much longer than the average. Most water heaters will last anywhere from 10-15 years with normal water conditions, somewhat shorter with mineral and sediment issues, etc. Since you've already flushed the tank, which is always the first thing to do, I think you've taken the right steps.

That being said, I believe your tank is failing and you should replace it soon, as having the contamination issues continue will reek havoc with your laundry and could ruin a lot of clothes.

Yes, getting 19 years is pretty good, but the time has come to replace it. Hope this helps you with your decision. Best Regards!

What can cause Hot/Cold spikes on an RTG74-XN


Crossover, low hot water flow, low water pressure, sediment in water lines or heater, heat exchanger needs to be de-limed, water filter needs to be cleaned, water heater temperature set too high, incoming water temperature too high or too low depending on model, MUD or PUD districts with pressure spikes, dirty faucet aerators, loose wires, bad sensor, faulty PD-board, bad venting, dirty burner and combustion parts, etc.

Crossover

Pilot light will not stay light


1) Open following link for how-to resources, illustrations, and service manuals for some brands of heater.
http://waterheatertimer.org/How-to-install-gas-water-heater.html#troubleshoot

2) Many things can cause pilot problems, including bad thermocouple, air in gas line, low gas pressure, negative pressure in house, bad venting, very hot attic, lack of combustion air, dirty combustion parts and dirty pilot tube, bad gas control, reversed polarity on electrical outlet.

3) If pilot flame is clear blue and strong, then next step is check that thermocouple sits in the flame, and then change thermocouple. This is start point. Following step would be reading service manual for exact troubleshoot and testing steps.

4) If pilot flame is yellow-or-orange or weak, then clean dirty combustion parts including pilot tube and air intake. Might want to change thermocouple while combustion parts are removed for cleaning.

Kenmore Water heater, Model # 153.339462, Pilot lights, burner burns for approx. 10 - 15 minutes then both go out. after which it is more difficult to light the pilot. I need ideas please


Clean combustion parts, clean air intake, get more air to water heater and see if problem continues.
Look at color of burner flame and pilot flame: if flame has yellow-and-orange instead of clear blue flame, then combustion parts need cleaning.

Pilot and burner problems can be caused by bad thermocouple, thermocouple not sitting in flame, weak pilot flame due to dirty tube or low gas pressure, air in gas line, no draft up vent, backdraft coming down vent, dirty combustion parts, clogged air intake, insufficient air, insufficient air quality, hot attic, bad gas control valve, etc.

Open following link for pdf resources, and illustrations for cleaning combustion parts, and some service manuals:

Suspects include bad thermocouple, thermocouple slipped down and not in pilot flame, dirty combustion parts and pilot tube, dirty air intake, backdraft caused by other vent fans pulling air down water heater vent, water dripping down vent because of poor venting, air in gas line, low gas pressure, bad gas control valve, hot attic environment, tight house not allowing enough air:

Rheem 22V50F1 pilot won't stay lit. Changed thermo couple & it lit, ran then went out. Let it sit overnight & it lit, ran then went out. What next? p.s. The unit is 5 years old. Thanks


If pilot lights and flame is robust and clear blue, and pilot goes out later, then some suspects can be excluded: air in gas line, low gas pressure, thermocouple is overtightened (finger-tight + 1/4 turn), thermocouple not positioned correctly in the flame, dirty pilot tube.
If flame is yellowish and small: then clean pilot tube and combustion parts.
http://waterheatertimer.org/How-to-install-gas-water-heater.html#clean
Remaining suspects can include: air in gas line, low gas pressure, bad gas control valve, tight house so household vent fans pull air down water heater vent that blows out pilot, hot attic with inadequate ventilation, water dripping down vent.
