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!

SOURCE: My Rheemglas fury 21DV50 hot water heater pilot

It could be a thermocouple but first take the whole pilot assembly out and disassemble it. Clean it very good (compressed air is ok) especially the orifice inside the pilot horn. You may just have a weak pilot. If the flame is in good contact with the thermocouple and problem still exist, then change the thermocouple. I believe in doing the free things first.

Rust in water, ao smith promax


It may be what is called iron bacteria it will sometime grow in a water heater. It is present in some water and will actually thrive in water temps up to 120 degrees.if this is the case one solution is to increase the water tempurature of the heater to 130 -140 degrees this will kill the bacteria that is causing the rust problem.You Must install a tempering or mixing valve which will add cold water to temper or cool the water back to 120.
hope this helps.

Insinkerator instant hot water faucet


Insinkerator stainless tank does not have anode rod to protect from rusting. So these water heaters rust out at welds. And must be replaced. And this is frequent problem.
Copy following link for installing under-counter water heater and see manuals for various models available. Non-insinkerator water heaters have anode rod to protect from rusting:

Replace rusted tank

Prevent rusted tank.
If nipples are leaking, and they did not leak before, then tank has most likely rusted out and needs replacement.
Cause for rusted tank is depleted anode rod.
Inspect and replace anode each 1-3 years.

My water heater is leaking and only 4 years old. Will the use of a water softener void the warranty?


The warranty should not be void by using water softener, BUT read product manual.
http://waterheatertimer.org/Water-heater-manufacturers.html

1) First thing: Why is water heater leaking? Where is the leak?
http://waterheatertimer.org/Leaking-water-heater.html
For example, if you have electric water heater leaking from element, then replace element.
Replace leaking TP valve.
If water is leaking down vent pipe, and combustion chamber rusted out, then vent problem must be corrected.
These are not covered by warranty.
If tank is rusted out, then read below.

2) If water heater is rusted out after 4 years, you might have stray current corrosion.
This happens when hot and cold pipes are not connected together with a ground wire, and/or if cold water pipe is not grounded to earth.
This might not be covered by warranty.

3) Read water heater instruction manual for advisories.
Tanks rust out when anode rod is depleted. Softened water depletes anode rod faster.
Instruction manual says to check anode rod each year.
Checking anode rod is like checking oil on an engine. If oil was never checked and engine burned up, the manufacturer will not honor the warranty.
If anode rod is depleted, and tank is rusted out, the warranty might not cover the rusted tank since owner was supposed to check for anode depletion.

4) Anode rods can also be covered with calcium deposits and stop working.
This night not have anything to do with water softener, but anode stops working and tanks rusts out.
In any case the owner's manual probably says to check anode rod to prevent leaking from rusted tank

Bubbling water at pressure releaf valve on top of valve. valve is rusted. rusty water in pan. Unit was installed new two years ago. Offer suggestions. Thanks


Rusted water usually means anode rod depleted and tank is rusting. Change 570241 anode rod every year or so.
Boiling water could mean bad thermostat causing run-away heating so water is released out of TP valve. Replace 994062 thermostat for 4 gallon.
Leaking water at TP valve could mean bad TP valve: replace TP valve with generic valve from hardware store.

I have a Reliance 501 electric water heater ... Everything works great but below the water out. Be rusty? How can I fix it?


The tank is rusting. Replace anode rod or replace water heater.
Once the anode rod depletes, then the tank starts to rust.
IF you can replace the anode rod, it will stop rusting, and then flush the rust out of water heater.
This might buy more life with same tank, but old anode rods are pretty solid and even impact wrench might not loosen it up.
http://waterheatertimer.org/Replace-anode-rod.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html#flush

Loosen anode rod on new tank before installing, and then inspect every 1-3 years, and 1-2 years if water is softened.

GE gas water heater smart shield manufactured date 10/2004. Water is rust colored. Have drained heater twice and it clears for a day or two and the rust color returns. Suggestions?


Anode rod is depleted and tank is rusting:
New anode rod will stop tank from additional rusting, but will not repair rust damage.
http://waterheatertimer.org/Replace-anode-rod.html

If rusting has been going on for a while, the steel tank could be weakened, and maybe rupture.
http://waterheatertimer.org/Water-heater-is-leaking.html

I suggest replacing water heater, loosening anode before install, and then checking anode rod each 2-5 years so tank last longer. Also add a ground wire between hot and cold pipes to avoid water heater deterioration from stray current.
Buy new water heater from local hardware or box store and offer 10% less than price, or have them install.

We have a Reliance 501 (40 gallon) natural gas water heater Model 5 40 NORT0 Serial F94799798. Does it have a glass liner?


Your Reliance serial number shows your water heater was made in July 1994.

Except for the Marathon water heaters, and copper-tank water heaters, all tank-type water heaters are made of steel. That steel has an enamel coating which people call a glass liner.

So in that sense, there is a glass liner.
See a photo of the liner:
http://waterheatertimer.org/images/Enamel-coated-steel-290.jpg

Also inside the tank is an anode rode.
The anode is made to protect the steel tank.
Anode is made from lower noble metal than steel, so water reacts with the lower noble metal first.
The water eats away the anode rod instead of rusting the tank.
Once the anode rod is gone, the water begins rusting the tank.
The enamel coating does not protect the steel from rusting.
The tank rusts away and begins to leak.
