Power filling from containers

Was dry camping with a friend of mine, who stopped for a water fill and managed to put 30 gallons into his fresh tank only to have it run out the bottom (he'd neglected to close the fresh tank drain, AND it was raining cats and dogs at the time).

Having had to refill the fresh tank while camped (and not wanting to move the trailer simply for water), it occurs to me that - IF PROPERLY EQUIPPED - you can attach a hose end to your antifreeze intake, and go:

container of water (to) antifreeze intake (to) water pump (to) showermiser (to) fresh water tank

and get an onboard-pump-powered fill to your fresh water tank without having to hold the container and pour into the fresh tank via the gravity fill on the side.

(granted, you prob want to make sure the antifreeze fill is clean and sanitized, having sanitized-then-flushed-with-fresh-water when you opened the trailer in the spring. You DID remember to do that, right?)

Things to make you go "hmmn."

make sure whatever you're pumping water FROM is as high as possible...
like in the Truck bed makes pumping easier for the pump

It may work when the FROM is on the ground but might be a lot slower

BUT ... if you can get the truck near the water IN port
you could just gravity feed it using a siphon
save pump usage and power especially if you boon docking

12v diaphragm pumps do NOT like to be pumping for extended periods.
tried emptying my boat's fresh water tank... by pumping the water out motor got real hot

If it was me... 2 or 3 of gallon water jugs from Wallyworld will be sufficient till I get to a fillup point.

Pay the money for one nights stay at a campground fill up
and while you're at it.... empty the black/gray tanks recharge the battery and do the laundry

PS.... Try not do any sweaty type exercises or manual labor until your water situation improves.

I do this quite often. I routed a hose to the outside shower area from the antifreeze winterizing valve. I rest a water container on a bumper storage box to gain height. On my outside shower, I remove the shower head and place the hose in the gravity fill port. I just use my regular water pump to transfer 6 gals at a time - takes just a few minutes. It works fine and I just fill up another jug whenever it's convenient for me. I agree that it might be hard on a pump to run a long time.

Every Thanksgiving we spend a week dry camping. In the past, would use spare water pump to transfer water into the RV. This time was the first time with this rig. Valve set to Winterize, Shower mizer on, short hose(4-5') from inlet to stick into the jug, and it worked GREAT! Turned the pump off between switching jugs, I had NO Problems. Transferred probably 60-70 gals, 6 or 7 gals at a time depending on jug size. I think I did it twice, so 5-6 jugs at a session. Pump never got hot.

Forgot, I just set the jug on the ground next to the compartment, sucked up fine.

I have an impeller pump set up with a length of wire and alligator clips that I connect to the tongue battery and pump water from a tank in the back of my tow vehicle.

I think the winterizing hose is a great idea though. I may abandon my method!

We don't have a shower miser, and as our trailer needs the fill to be pressurized, we use a spare water pump to pump into our trailer. We've done it from 5 gallon jugs, and even a bucket that a garden hose was filling.

I use a 12 volt transfer pump that I wired to a 7 pin connector so that I could easily power it using my truck. I bought it at Harbor Freight but I've heard of others that buy a water pump identical to their camper's pump that can be used as a spare in the event of a pump failure. I leave the water jugs in the truck and can fill my water tank in less than 10 minutes. It's much easier than holding the containers while pouring into the fill port.

Will the antifreeze input port really fill the freshwater tank? Why? No antifreeze is needed there.

35 water tank from the "Farm Store" (Tractor Supply, etc.) and a 12v water pump handles this chore for our dry camping treks. Fill this tank and pump it our right from the bed of the truck or the back of my SUV. Daily after breakfast chore for me is to tow the waste tote to the dump station, empty it, and fill and return with this tank full of fresh water. Tank weighs about 300 pounds full of water.



The water pump we use is the original, noisy pump from the Roo which was replaced by a much quieter pump -- you always wanted a quiet pump so here's the justification.

The "magic" making this particular fill possible with no additional stuff to purchase (for properly equipped travel trailers) is the Showermiser water diverter - which is designed to recirc water being supplied to the shower into the fresh water tank (handily reducing water usage, such as if you are "waiting" for the shower to get hot).

Antifreeze port (to) water pump (to) showermiser diverter (to) freshwater tank.

I DO like the siphon idea, too, especially for larger, truck mounted tanks 'n totes.

Your mileage may (and likely does) vary.

With no shower miser, on board power fill isn't an option for us. So for now, we're using the 5 gal collapsible jugs but I have no intention of holding them. The bed rail of my truck is plenty high to gravity fill, via a short length of hose.

If we decide that ten gallons at a time is unacceptable, I guess we'll get a bladder and a pump matching what is in the trailer, for a spare.

Sounds like you're all set (and a siphon from the truck bed sure seems easy)!

Of course, if you can fit a hose/end over the outdoor kitchen water water supply line, it seems like you could actually go:

antifreeze port (to) Water pump (to) outdoor kitchen (to - via a long hose) gravity fill port.... but that seems to be getting ridiculous, involving three of the four corners, and a long hose run.

I didn't see an outdoor shower on your 252RBLE, but it's possible to also use that as a water OUTPUT source.

Just my .02. Hope this helps.

Yeah, no o/s shower but there is an o/s spray port to do as you mention. Just seems a lot more hassle than a short hose from the bed rail.

WAY more hassle. Mostly, it's just an exercise in figuring solutions to things that cause more problems than they solve. Good times in camp!

I have a 20 gallon tank approved for drinking water. I cheated. While approved it is actually a tank for a spray rig from the farm store. It has a hose attachment. I use a 5' hose connected to the antifreeze inlet and use the power fill setting. It works great. Definitely better with the tank on the tailgate than on the ground.
