Water heater: warm, not hot
Suburban water heater intermittently gives hot shower water, but mostly warm. I replaced the anode rod in the spring, thinking that would help but it didn't. Now that's it's getting colder... doub...

As posted ..anode rod has NOTHING to do with water temp. It is a sacrificial rod to provide protection for the STEEL tank Suburban uses and help minimize corrosion.
Water temp is a function of HEATING the water
Propane has its own set of t-stats to control temp of water
Electric has its own set of t-stats to control temp of water (if WH has electric)
Both control water temp to 130*F/Normal
IF the corresponding normal t-stat FAILS then water can be over heated. Hi Temp T-stat/ECO shuts down heating at 170*F
Typically normal t-stat issue result in too hot or NO heating----not warm heating
So water S/B HOT inside WH TANK and output temp is getting diluted by Cold water mixing with the HOT out.
Bypass valve cracked open....water from cold inlet goes directly to hot outlet
Shower (inside/outside) not shut off via cold/hot knobs but just with 'button' on shower handle---cold/hot mix inside shower faucet.
Either one...result is luke warm water. Can be bursts of HOT when first opening a faucet then it goes warm
Cold mixing with HOT...check all valving etc.
