A question was asked under the General/Technical section on an easy way to fill the fresh water tank other than through the City Water connection, i.e., via a funnel, etc. I did the funnel thing for several years until I came up with the idea of adding a water pump to move water directly from our jerry cans to the fresh water tank. After I posted the following solution in response to that question, Joe suggested that I also post it under this section of the Forum.
Basically, I used a Flojet Quiet Quad II water pump from Camping World ($70) because it was easily available, designed to pump water, and is self-priming. We have an EB-50 with a water heater so I mounted the pump inside the water heater cabinet. The piping configuration was based primarily on the availability of various couplings available at the hardware store. The inlet to the pump is connected to a female water hose fitting which extends through the water heater cabinet. From that fitting, I can attach a 2' long piece of reinforced water hose and to that, a piece of 1/2" PVC. That lets me insert the PVC pipe into the jerry can and suck water from the bottom of the jerry can.
To use the setup, I hook up the 2' long hose and PVC pipe to the connection at the rear of our van, turn the SMB valve on the water tank to the "fill" position, and turn on the pump.
Here are some photos of my installation. The first photo shows the rear of the van. The white box is the cabinet for the hot water heater. The connection to the water pump is the brass fitting on the lower right. (There is a female cap on the fitting to keep dust out.) The switch for the pump is in the upper left.
Here is the same view with the hose hooked up. The short hose connects to a piece of PVC which is inserted in the jerry can. The PVC has a valve on the upper end which allows it to be "turned off" to keep dust out; there is a PVC cap on the other end when stowed.
Here is the system ready to pump:
This view looks inside the water heater cabinet. The pump is bolted to the rear wall of the cabinet. Power is fed from a 12v source with the hot lead wired into the toggle switch. The inlet side of the pump is connected, via flexible hose, to the brass fitting visible in the first photo. The outlet of the pump connects to a flexible hose which snakes through the cabinets to the water tank under the sofa.
Here is the connection to the water tank. I removed the SMB-provided cap and replaced it with a 90 degree street elbow fitting. The hose from the pump attached to this elbow.
Although not directly related, here is the jerry can basket after the locking bracket is back in place:
