RV Water heater

Agree. No noise on electric. If the weather is cold we run the WH on both electric and propane at the same time to improve recovery rate. And the electric keeps the water hot enough that the propane never comes on unless we are using enough hot water at the time to require propane to help reheat the water. So no noise at night.

If it's electric and propane run it on electric.

What Brand AND Model????
ONLY Suburban uses an 'anode rod' ----NOT Atwood

To drain/flush
Turn water supply OFF
Relieve system pressure by opening a Faucet Hot/Cold Sides-----leave it open
Remove drain plug ---water WILL flow out emptying the WH Tank
I turn water supply back on ---turn faucet off and let water Blast out WH TANK drain hole. CAUTION: Stand Back as it will BLAST out

Turn water supply back off....install drain plug (new anode rod if Suburban) and open faucet hotside to bleed air out of plumbing system and allow WH Tank to fill.
Water flows/no air from faucet-----done


Nosey FLAME on water heater
Atwood has an adjustable air shutter
Suburban no air shutter so could be dirty orifice, dirty burner tube etc

WHAT water heater do you have????

Yep. Just shut it down.

I’m not “afraid” of my TT water heater but I’ve never left it on, propane or electric, overnight. Yes, the fridge is on however. Fill and drain twice is the only flushing I’ve done, once a year or so.

I never turn mine off when camping, but then mine isn't next to my bed, but if it were, I'd agree with the others and just turn it off before retiring.
Do I assume it's only noisey when on propane ? I've never heard mine when on electric.

Sorry to be a pest but what is involved in cleaning out the water heater? Open the PSV and flush?

Maybe it needs cleaning or adjusting. Otherwise just turn it off at night.

Speaking for myself, I turn it off at night so I don't have to listen to it run.
Water will stay hot for quite a while, and still plenty warm in the morning.
I just flip the switch when I get up in the morning to make my first coffee and let it cycle.

The anode is not related to the sound it makes running.
