Water pump for water barrel...

[OregonTRX4]

I have a 55gal water barrel that I use to fill my water tank since I keep my trailer off grid i the mountans on private property. I was thinking i could hook a 12v pump to the barrel and then to a hose to wash the trailer. Anyone have any setups like this our suggestions? Thanks

Why don't you just put a threaded end on a interior faucet, and pass a hose through the window?

Just put a threaded 3/4" connection on low point drain.......hook up hose, turn on pump open low point drain valve and wash away.

Thanks for all the great ideas everyone! Another reason I thought having a pump on the tank on the truck would be for possible help if a small fire were to break out.

A normal RV water pump can take water from 4' below the pump location. It helps if the pump and tank water level are close while the pump is taking in air, and getting primed, but it is not a requirement to have the pump below the water level while pumping, because it is a diaphram pump, and can take in negative water pressure up to about 10' of suction depth.

So I would get a normal 12 volt RV pump, attach a 10' hose to both ends and pump the water either into the fresh water tank in the RV or into the fresh water inlet. You can even get really clever and mount a additional tank on the RV roof, then fill it with the pump, and have a valve going to the fresh water tank, letting it gravity fill as you need it. In theory, you could fill the 55 gallon tank 3 days a week, and fill the fresh water tanks in the RV (including a new roof one) only a few days per month, saving time.

RJsfishin, how much would that waterboy cost? It looks interesting. I can't find any info on that site. Tahnks.

If you already have a good size 12v to 120v inverter in your trailer I would go for a 120 volt water pump, many pump options at a good price. That way you can use regular extension cords and go much longer distances if needed, 12volt dc wire runs need to be fairly short.

I have a pump and setup for pulling water out of a stream or lake and decided to go 120 volt.

Have seen several set ups like this over the years.. You have two choices in the 12 volt pump.

1: Standard RV pump.. Advantage this method... If your main RV pump ever conks out on you you can pirate the barrel's pump as a spare till you get to town for a new one.

2; Harbor Freight has some 12 volt pumps as I recall.

3: use a 120 volt pump (Small one) many sources.

I have that setup to pump water into my fresh water tank from 5 gallon jerry cans while boondocking (2 cans, 4 trips fills the tank). Works like a champ.

Side benefit, if the pump in the RV ever dies, I have a spare on board already since the pump I use is the same one that was installed OEM.

I have a Nomad Portable 12v pressure washer.. works great, uses less water and good pressure
check it out Nomad website

They sell those barrel pump assys here in Quartzsite.

I myself use this,...works good

I bought one of these Harbor freight 12v utility pumps a few years ago. It will move a good bit of water but I don't know what kind of pressure you can develop. Shur-flo sells a variety of 12V diaphragm pressure pumps. I have one on my tractor spray tank and use it to spray trees. It develops enough pressure to spray vertical up to 30'.

I used to use a 45 gallon barrel and now have a 50 gallon container(agriculture) that goes in the bed in front of the 5th wheel and fits under the tonneau cover when not towing.There is a tap installed on the bottom end of the container. I also have a 45 gallon collapsible container(from Camping World) and that goes behind the 5th wheel cross ways with a furniture blanket under it so it doesn't get damaged by whatever gets in the bed of the truck. We use it because we also camp off the grid a lot. I used to use my air compressor with the 45 gallon barrel to move the water from it to the 5er but now use a 12 volt pump. It works very well and is a lot faster than air pressure.I tried gravity feeding it but can't always get the tank higher than the fill. I had to rig up a double female, end hose to go from the container to the pump. My three kids also use a 12 volt pump to transfer water. They all have the collapsible containers. I found a plug http://www.princessauto.com/pal/en/Other/7-pin-Trailer-Plug/8462558.p that goes into the rear receptacle of the truck and I put plug ends onto the wiring of the pump and a cigarette lighter end which plugs into the receptacle of the truck. No more long extensions to get 12 volts.

Yep, I have the same for filling our trailer with fresh water except I use a 75 gallon water bladder. I bought a rv water pump and have a extension cord to go to the trailer batteries. Work great.
