2900LE hot water tank

[Bigstatik]

Noob question....

How do I "fill" it?

ETA: nevermind, I understand it now.
Turn on a hot water faucet and let it fill.

[rgarner]

If your hot water tank has an electric switch (often on the outside access) in addition to the 'gas', you will want to check and make sure it is off if the tank is ever empty---as this can quickly burn up the heating element.

The water tank fills (if it was empty) as soon as you turn the pump on or connect to city water if the valves at the back of the water heater have not been set to bypass it.

Clarifying question. Does it fill (if empty) by just turning on the pump or do you also have to turn on a hot tap?

Even though I am a noob I would think the tap would have to be open to allow the air to escape to make room for the water.

ps: previous owner didnt tighten the heating element after a winterization.
do I need to put antisieze on it? and how tight?

[MotocrossCamper]

It's easier to just open the release valve on the water heater when your filling it. Pushes all the air out as it fills and you don't have to deal with spitting water out of your faucets.

Was that the element with wires or the other plug holding the anode rod? Use non hardening pipe dope and tighten till it doesn't leak under test pressure. No more than that, you'll have a hard time getting it out next time.

[Bigstatik]

I believe its the plug with anode.
havent had time to go check it.

[Bigstatik]

ok, more help please.
I have the water heater filled and would like to test for hot water.
propane tank is empty, what exactly do I have to do to get it heating on electric.
there are the two rubber buttons above the anode but they are dry rotted with holes, cant read em either.

[rgarner]

Mine is more of a switch; however, it is likely the case that one is "on" and the other is the "off" electric for your water heater. (Of course, also not likely good that they are 'rotted' as this may indicate that they may not make 'contact' to properly function.) You might be able to tell which one is currently depressed by feeling; however, if you do not have water getting hot after a little while, push the other one and that should be the "on." (Assuming that the contacts are not corroded and neither of them function.)

Hope that helps!

thanks.
going out there to try now. I dont want to get zapped because you cant press the rubber button with your finger going through the hole in the rubber.

Hot tap has to be on, or da water has no place to pump to.

ok, those rubber buttons are the reset. its a plastic flip switch near the bottom. elec water works, yay.
red led rocker switch inside that says "heater" is just for propane water heater?

some heaters don't have electric, some have a switch inside the camper, and some have a small switch below those button you are talking about.

Those buttons are probable the limit switches not the on off switch.

[RvBill3]

Electric switch is on the heater itself, accessible from the outside. Lower left corner somewhat hidden. Inside switch is for propane. Both can be used for faster recovery as propane is faster, otherwise use electric from campground and save your propane.

Those buttons are 'reset' buttons for (I think) overtemp protectors. WRT using electric heat, once tank is filled, you'll find a switch nestled behind the pressure relief valve labeled on-off. Turn it on with a/c power on coach and the heater should heat.
