Will the brass fitting in the picture pull suction from a water bladder?
We will be boondocking after Christmas and intend to use a water bladder to refill when I donít feel like moving the coach!

Hard to say by the picture but there is only one way to find out. Hook up a hose into a bucket of water and turn the pump on.....see what happens

Yes, remove brass cap and attach a short hose, then turn on the water pump. It should suck water from a bladder or bucket. This inlet is also used to suck RV antifreeze from a container thru to all the RV's plumbing and water pump to "winterize" RV.

That will pull water from an outside container, but it won't refill your fresh water tank if that's what you intended.


As posted, it is used to winterize the system. Turning the valve to INLET connects the fitting in your picture to a point between the fresh water tank pipe and the pump, but that point shuts off the flow of water from the tank to the pump and replaces it with the connection to the inlet.


Drawing water in through the inlet and then through the pump will fill the system and pressurize it, but no water will flow into the tank because of the CITY WATER valve. If it's set to CITY, it isolates the pipes in the system from the fresh water tank. If it's set to TANK FILL, the pipe to the fresh tank is open only to the outside fitting for filling, not to the pipes from the system that are fed by the pump.


I suppose it's possible to move the CITY water valve part way between the two positions, creating a "leak" at the valve itself, allowing pressurized water from the pump/system to leak back into the tank. It will not come out the CITY fill connection due to a check valve.


Look at this diagram, specifically the upper right corner and the area by the pump. Your system is probably similar.

Many of the snow birds use a stand alone pump and get power from the trailer light plug. This way you can pump water to where you want, can help out a friend that may be short on water.

I use that to add water to my tank with some modification. I modified the outside shower to connect it to the water inlet.I open the cold water and turn on the pump.The water goes into the pump, out the shower and into the tank.When thru pumping close the shower and switch back to normal.
