Hey, Fred:

No worries.  I'm capable of some pretty dumb stuff!  On this trip, I left the keys to the trailer behind--Doh!  Fortunately, we had keys to the trailer we're selling, and it turns out the storage locks are the same--and we hadn't locked the main door--so all was saved, included any $$ for a locksmith.  I'm sure there is/was something pretty simply going on.  I just wasn't there to see it.

I have a note on my dash that reads 9' 6"!!!

Afraid I might forget and drive under a low bridge! Smile

One other place to check is behind the access panel to the bathroom sink. Bedside of bathroom wall. Look for wettage.

I think of 10' as the lowest I will go. Allows a couple inches of bounce space.

If you put city water to the backflush you will fill the black tank, if the water pump check is failing to close you will put city water in the FW tank. Do you have the common drains, where the gray and black drain from same drain? Normally the gray tank gets water from the shower and two sinks.

There SHOULD NOT be any path from the FW supply to the gray tank that doesn't involve a faucet. That said, never underestimate the creativity of the FR shop assemblers. We've seen strange wiring and loose/backwards plumbing but this is a new one. Keep us posted.

Yeah, got the BW flush figured out.  I'm thinking a faucet must have been maybe a little open and I didn't hear it because of the AC.  With high pressure on the line from the hose, that might have pushed a fair amount of water out, eventually filling the tank.  Now, some water did flow out over the shower pan, but virtually all of it seemed to drain out underneath.  The floor inside the trailer only had a small amount of water visible--like easily mopped up with a towel.  Is there a secondary drain under there?  Should I worry about water damage?  The weather has been hot and dry, and we did a three + hour drive home in 90+ temps the day after the incident.  I think it's pretty darn dried out now.  What should I check?

Thanks.

Hey, Podsters:

There IS a potential pathway for freshwater to the grey tank.  Dig this hot off the presses from Forest River:

Scott,

        It sounds like the check valve in your water pump may have gone bad. Typically if the check valve in the water pump goes out, the city water will end up filling the grey tank.

So, folks, any tips/tricks/guidance to accessing and servicing this valve?  Will I have to replace the whole pump?  Thanks.


Scott
