Where is it: Gravity Feed 39R12

[TBKHomeworld]

I feel horrible for having to ask this, I've looked all over with no success. I am trying to locate the gravity feed for our fresh water on the 39R12 but I can't seem to find it. The dealer was unaware if it had one when we purchased it.

Does anyone know if the 39R12 has one?
If it does, where is it located?

Thanks!

Some RV's don't have a gravity fill port on the fresh water tank. My trailer has a hose connection separate from the city water, others use the same connection for city water with a diverter valve to direct the water to the fw tank. Some RV's have the water connections inside a door with the diverter valve lever. Sometimes the diverter combines the city fill, fw fill, winterizing or black tank flush all in one valve.

If you post a picture of your water connections we could help you better.

My Mirada motor home has a hose connection for the fresh water tank that has a back flow feature built into it. The only way to fill the tank is from a pressurized hose. You need to have enough pressure to overcome that valve.

Took some photos as requested.

This is what I'm figuring mine has as well. I was thinking about buying a drill powered water pump and putting a hose connector on the output side. Hopefully it can build up enough pressure to overcome the valve.

I don’t have a MH but my camper is the same way.. I ended up buying a replacement water pump that I have wires hooked up for battery or plugin that I pump from jugs to camper. Seems like a stupid idea not to have a gravity fill but this works for the few times I’ve used it.

My thinking was, if original pump went out, I would have a replacement. I just keep the hoses and pump in a storage box.

It doesn't take a lot of pressure to unseat the check valve in the fw fill. If you use one of the hand pumps, that you would use to add antifreeze from the bottle, it works. You could use the same hand pump to add fresh water if you don't mind using a little elbow grease. It will empty a gallon jug of antifreeze with just 10 or 12 pumps and very little resistance. Or use it as a back-up in case your made up electric pump fails.

You will connect your pressurized water hose to the connection I circled in your photo to fill your fresh water tank. You do not have a gravity fill port.

I have no clue how your dealer didn't understand this. Shame on them

I don't have such a fancy rig but my little pea brain says to remove the black cap from the "fresh water fill" and attach a hose. (If that's what I see in the picture) But I have been known to be wrong.

Thanks everyone for the responses!! Greatly appreciate the info and help.

All of my other travel trailers and my friends trailers have always had a gravity feed. I just found it odd and was confused since it looks like high pressure, can't just pour water in, etc.

Pretty obvious for the seasoned but I was curious if maybe it was stuck under a cabinet, behind a panel, etc and I was just unaware.

Thanks again.

I have a feeling that they use this type of connection because the fresh water tank is at or above the level of the connection. If they used gravity flow w/o the check valve you would lose too much water just by driving around.

Is that all the inlets in your Wet bay, or do you have an antifreeze inlet as well? If you have an antifreeze inlet, you can use that to fill the FW tank as well. Just do this:

1) Put a hose from anti-freeze inlet to water source.
2) Flip the switch to draw from the antifreeze inlet.
3) Connect the outside sprayer hose to the tap shown below the tank valves in your second picture.
4) Connect that hose to the FW inlet connection (middle one in the top picture)
5) Turn on the water pump, pressurize the system
6) Open the cold water on the tap

This should then use your onboard water pump to draw from the antifreeze inlet, through the outside tap and into the FW tank. Minimal outlay other than a length of hose and maybe a couple of couplers. Then,

7) Once the container is empty shut off the tap, shut off the pump, and then disconnect everything, switch back to normal usage.

Any idea as to how I would sanitize? Add bleach/water solution to the fresh water tank?

That’s what I do. Sanitizes the FW tank too that way.
