Water System Issue

[digNbubbs]

My one year warranty must be up - having a couple of issues.

In the past couple of weeks, we left Texas and went to Colofreezing. We left there Sunday (the warmest day of our stay...) and drove to Santa Fe. After work today, drove from S.Fe to Flagstaff.

Two of my three issues didn't show up until today. When leaving today, I was filling the fresh water a bit and walked back to turn the hose off at the hydrant. When I released my quick disconnect on the regulator there was a bit of pressure, and more water than usual was draining from the hose. I went back to the wet bay and heard the water pump going. I closed the fill valve and the pump kept running. It was filling the hose and pumping out - out through the in door.

I changed positions of the fill handle, cycled the pump several times, many combinations of things. They all turned out the same. Needing the water pump for the road trip, I put a shut off on the end of the hose and turned on the pump. It filled the hose to just over 40psi and shut off.

I figured there must be a check valve that diverts whatever is supplying the system with pressure. I rigged it for the drive, and it actually worked out because the hose acts as a big expansion tank

The above events happened on the one time I broke my normal pattern for disconnecting my umbilicals. That'll teach me to stray the course.

My other issue is that we came back into the bedroom and it really smelled of exhaust or fuel - mostly exhaust. It has never done that in 22k of our miles. I think I will go out now and have a smoke and look around for more fuel dripping...

I won't get started on the door issue.

Any thoughts about the check valve? In the manual? I will call tech support tomorrow. Just figured I would give the voice of experience a try first.

Hi Kev,
Hmmmm....that sounds wierd. It does sound as if there is a check valve in your fill system. It also sounds wierd that your water pump was running. I always shut mine off when I fill. Actually it's usually off anyway because I'm usually hooked up. But it does make sense to me that a check valve is stuck open, hence the pump running. I learn something new every day I'm on this site. Keep us informed and good luck.

Hi Kev and Ang!!
Kev, you may want to check out this thread concerning the exhaust smell.
It is on the cat C7 but may also pertain to ours. Smlranger also links to another post that shows a good pic. </div></BLOCKQUOTE>

Hey stranger! Thanks a lot for the link. I am going to check out those items before we leave this afternoon.

Yea, I do too. I think Ang may have kicked it on sometime in there, anticipating the water being turned off. I should have checked better when I was doing all of that, but didn't. I will next time

My check-valve dribbles a bit, but not bad enough yet to get around to hunting it down and fixing it. I've been told the check-valve is in the pump-assembly base itself and also told it was in the line before the pump. Sorry if this isn't much help, Kev, it's one of the few things I've not disassembled yet, but my vote is within the pump-base.


Know what you mean about disrupting the normal sequence of events. I get so absorbed at docking/undocking time that I'm sure people have talked to me but I'm so absorbed in going thru my routine that I flat-out don't hear them (at least that's the story I'm sticking with when my wife calls me!)
