I'm not familiar with your RV but siphoning is usually caused from the tank not venting air when it's filled. If you have a valve that allows you to turn it, when hooked up to city water, to fill your tank, then there may also be a separate filler inlet to use a hose to gravity fill directly into the tank. I have two different ways to fill the tank and the gravity fill has to be open to vent the tank when using the valve knob switched to "Fill Water Tank". Hope this makes sense. If you check the manual, it will tell you if you have the second inlet. If you don't have it, then the vent hose needs to be adjusted or you can put the shut-off valve on the overflow pipe. Make sure to open it when filling or your water tank will expand and can be damaged. My Cardinal fifth wheel didn't vent properly and the tank would "balloon" when filled!
