Replacing Water Pump – How to get to it

vairman

I have the same problem with others and my fresh water tank is filling up. For others who have removed their pump, how did you get to it. I tried moving the wall but that didn’t get much more access. I am contemplating removing the outside water panel to gain access but I was hoping there is an easier way.

Between the wires and hoses, it seems impossible to get to without removing all water and electrical connections and on 2013 LS 36FW, there is a lot of connections.

In my career, I spent time as a maintainability engineer. This design would have failed miserably.

Thanks in advance for any insight.

I replaced ours recently…. it is a job. I basically unwired and rerouted everything I could to make the area neater. I disconnected the fill line, the vent line to the tank and removed them from the convenience center. Then I disconnected the lines for the outside shower and pushed them up out of the way. This gave me enough room to remove the pump from the front wall, once down, I unhooked the water lines to it. Disconnect your city water first and drain down the water system at the low point drains. I turned off the water heater as well. I built a shelf that I mounted the new pump on and mounted it in the main compartment above the little sliding access door. Rerouted the water lines to it making future replacement easier.

I had the same problem with my water pump in my 35SB3. I was going to get a rebuild kit but it was going to take to long to get, so I just bought a new pump and installed it. It too was a bear to get out and the new one in. About a month later it started doing the same thing as the old one was doing, letting the water bypass the internal check valve and filling the tank. My solution was to put a small brass check valve in the suction line just on top of the winterizing valve. I have not had a problem with it since in well over a year and a half.

if all else fails, do what I did after replacing the pump and installing a check valve that blew directly between the outgoing water line and the pump. After the pump, install a shut off valve. This will not let water back to the holding tank and you can open it when the pump will be used. You will need some conversion hardware to change from one type of tubing to another, but it does work great.

Wow, that’s quite a job. On my 37IK it took about 20 minutes for me to change it out. Unfortunately the RV designers don’t have to work on ’em…

I’ve also experienced back-leakage thru the pump causing the FW tank to overflow out of the fill connection. To stop the backflow til i could get the pump taken care of I repositioned the winterizing valve at the suction of the pump. This isolates the FW tank from the pump suction and lines up the winterization hose to the FW tank so you’ll need to either cap the hose or ensure the hose end is higher than the level in the FW tank. Also, you don’t want to run the pump while it’s isolated from the FW tank. I put some reminder ‘stickies’ on the pump switches cause i know how ‘good’ my memory is.

Thanks all. Shadow, I did exactly what you did to make sure that I was not filling the FW tank but now it is time to make a more permanent solution. Jim, I have already scoped out the new location and that is a perfect solution. I need to find a warm day. We are in Atlanta now and the weather has been horrible, temp wise. That will also allow me to clean up the mess of wires and piping.

Thanks again for all of the great help. I knew you guys would come through.
