Loading Water in Boondock Mode

[HDRider]

It loaded about 1 gallon, but would not load more.

 

Can someone suggest troubleshooting steps?

 

The pump is running and the valves are properly set.

 

Thanks

I assume you are trying to fill your fresh tank from a "container" using your rear boondocking port to suck in water through the on board pump.

Q) Was the pump able to pump any water out of your tank before you started? It may have lost prime.
If you lose prime you can often get it to reprime by either removing and checking the water filter (near the pump) or by opening and closing each of the valves and ending back on the boon docking configuration.

Our 2019 Has this Valve Configuration...not sure if it's the same for you but just as a cross check for sucking in thru our rear port.

How long is the hose you're using to the container? It works best with a short piece of hose.

I've pumped from our 35-gal aux tank in the truck about 30 times. Only once it would not pump. My son was using the Oliver and he's new with RV stuff. He kept trying the water. Normally, when we here a first gurgle from the pump, we stop and refill the tank. Yes, when you loose prime, water will not pump regardless of the valve configuration.

To fill water that one time, we had to tow to use a pressurized hose. I filled the FWT, then primed from the boondocking port and finally attached the hose to the City Water inlet to prime all faucets, the HWH and toilet. I wanted everything full!

Also, we pump often when the truck is attached or at a distance, so I connect the 10 ft plus 25 ft hoses we carry, from truck bed to boondock port. Length of hose has not mattered in our case. However, OTT installs a basic water pump which we replaced with a REMCO US-made variable speed pump, with a little PSI and GPM bump over th OEM pump. 😎

I suspect that is what happened.

It is less than two feet.

Assuming the valve set up is correct, and the pump screen is not plugged, them many have found that the boondock hose seal was worn or the boondock hose fitting was not FULLY and FIRMLY tightened.  As a result, that connection sucks air and little or no water moves on board.  

Suggest double checking that connection and raising the boondock container as high as you can so reduce the hydrostatic head to the pump.  This will assist in getting the pump to self prime.  Ours takes about a minute a gallon to boondock onboard.  

Hope this helps

sucks air

I carry a backup pump and have had to use it to fill through the normal fill port (not the rear suction port.)

If you ever want to build a backup pump system...here's our article on that topic.

Hope some of the comments like  the one above about checking for air leaks have helped.

Let us know your outcome.

It had lost prime.

 

I connected city water to boondock connection.  Turned on water for 20 seconds or so.  Connected my boondock hose to boondock port.  Turned on pump.  Sucked up a gallon of water lickety split.
