Trail-Lite RV has pump and electrical issues


gary-736Dear Gary,
I recently purchased a 2007 R-Vision Trail-Lite RV. I live in Iowa and am trying to winterize it but when I put the RV antifreeze in, I can’t get it to circulate throughout the system. Am I doing something wrong or do you think I have a bad pump? The owner’s manual has very sparse information. I also have a couple of plug-ins that don’t have any juice. Do you happen to know where I can get an electrical diagram for this camper? Thanks! —Bill A.

Dear Bill,
rv-antifreeze-rv-doc-rvt-769The easiest way to induce the RV antifreeze into the system is to pour a couple gallons directly into the fresh water tank and allow the 12-volt pump to pump it through the system. Are you saying your water pump won’t operate at all? You can also empty the tank, disconnect the hose leading to the water pump inlet and insert that hose into a bottle of RV antifreeze, but that still requires the RV’s water pump.

There are also kits available that attach to the kitchen faucet where you can “back fill” the system using a manual hand pump. Some RVs are equipped with a “tee” fitting and valve located between the tank and pump that permits a short section of hose to be inserted directly into the bottle of RV antifreeze. These types of kits can easily be added after the fact. Some even come equipped with a separate, permanent tank for the antifreeze. But if it pumps water, it will pump antifreeze.

gfciI’m assuming the “plug-ins” you refer to are 120-volt AC receptacles. If all the circuit breakers are turned on and you do have power at other receptacles, check the GFCI mounted in the lavatory or galley. It’s likely tripped and is protecting more than just that receptacle. Simply push the reset button and then check those other receptacles. GFCIs are usually configured to protect the bathroom and/or galley circuit plus all other receptacles installed downstream of that one.

Personally, I do not have source for an electrical diagram (if one even exists). R-Vision does, however, have an active club online at this website. But, alas, you must be a member to search the forum. I’d suggest you join that organization (it’s free) and see if any of the members have access to the diagram you are looking for. Individual brand RV clubs are great sources of information, from owner to owner. Almost certainly you’ll gain additional help from that group.

I had the same issue this week with my 2000 Trailite Travel Trailer when I tried to winterize it. The pump just hums softly and can not get it to pump water. I also could not figure out how to get the antifreeze I put into the potable water tank out. Am I missing something I can not find a drain plug.

I blow down my water system with air (30-35 PSI) hooked to the city water connection and then winterize with antifreeze pumped via my 12 volt water system pump. If you don’t let the air out of the system the pump will not pump up the antifreeze. Release the air off the hot and cold water side and try again.

My son had the same issue when he did his RV this year.
