We purchased a 2022 Winnebago Travato 59K in October 2021. We took it on one small trip to see if everything was working and now we’re on our first big trip. The first thing that’s gone out, and I’ve had nothing but problems with, is this new water pump all in one unit. I’ve had the technicians come up and look at it twice now. Each time they’re able to get it to prime and to work, but when it gets on the road apparently something goes wrong with one of the levers and we cannot get it to prime. We put the fresh water on and made sure that there was no air in any of the lines, including the shower, the kitchen sink and the bathroom sink.
It seems to me this unit is more trouble than it’s worth. We figured out how to attach an angle brass fitting, run a small hose, and put a hose bib on the outside of the van. For some reason, Winnebago decided to make something that you couldn’t put your hose in. You’d have to leave the back door open, which is the stupidest thing ever.
RV has to go back to shop because water pump doesn’t work again
Now it’s going to have to go back to the shop because the first day of our trip it no longer works, so I have no water. Do you have any suggestions on these new units? From everything I’ve read, this seems to be an ongoing problem with these white boxes that you change the valve on the direction you want your water to flow. I understand why Winnebago wanted it to be more all-weather, but in doing that they’ve created something, in my opinion, that is nothing but trouble.
This is our fourth RV and on all of our RVs we’ve never had as much trouble trying to get our water pump to work than we have with this. I would greatly appreciate any tips on how to prime this thing. Thank you. —Peni
The first step is to call Winnebago Customer Care and get the situation documented before it goes out of warranty. The “white boxes that you change the valve on the direction you want your water to flow” is a simple set of valves used when connected to city water to change the flow either to city water to provide pressurized water to the faucets, or to the fresh water tank. This allows you to fill the tank without removing the hose and putting inside a gravity fill. It does not do anything to the pump. There are also valves to draw in a sanitizing solution or RV antifreeze, which I’ll talk about later.
Description of the water pump
Your water pump is a Shurflo owned by Pentex and there are a few items I would suggest looking at. First is the screen that filters the incoming water on the inlet side. If the fitting is loose or the bowl cracked, it will draw air and not allow it to pump.
Next, make sure you do not have the winterizing or sanitizing valve open. This valve switches the draw of the water pump from the fresh water tank to the tube. That allows you to draw RV antifreeze to winterize the plumbing pipes or draw in a solution of bleach and water to sanitize the tank.
The water center (controls)
This is your water center with the valves to direct water for dry camping, winterizing, filling the tank, sanitizing, and using city water. This is the setting you want for dry camping and using the water pump. If you have the valves set for winterizing. it will switch to allow a draw hose to be connected to the fill valve and draw antifreeze by sticking the hose in a jug of antifreeze. If there is no hose connected and no antifreeze, the pump will draw air out of the fill valve.
Below is a photo of the center with the valves in the winterize position. Even if you do not have a hose and the cover is on, it will still try to draw from there and not the fresh water tank and will draw air.
If you have the valves in the dry camping configuration and it still does not prime, try installing the hose and put the hose in a bucket of water. If the pump does prime, the valve is bad. However, if it still does not prime, then it is the pump.
Water pump could be replaced
I contacted Winnebago Customer Care and they did indicate there were some issues with the pumps losing prime due to an issue with the diaphragm. They will replace the pump under warranty if that is the case. Make sure you contact them and take it into a certified Winnebago service center.
