Thank you everyone. Great suggestions and we can look Friday and let you know what we see. I did look at the manuals but unfortunately it doesn't give me enough info. We did locate another handle under the slider by tires black handle. Manual doesn't say what it is. I was afraid to pull it as I thought it is a manual lever to disengage the auto slider. Old biscuit I think this is what your referring to. I'm going to pull it. One question should it stay open? Thanks you.
Handle look just like the other dump valve handles?
It is most likely the dump valve for galley tank (kitchen sink).
Tank is FULL.
Tank full and kitchen sink NOT backing up means water is running out of:
*cracked drain line from sink to tank
*loose fitting on drain line from sink to tank
*out of top of tank where drain line from sink connects......grommet/gasket bad/pushed out of place.
Drain the tank......you can leave it open (unlike black tank.never leave open). Just be aware that "sewer flies" can come up hose and set up house in the tank, odors can come inside rig IF sink 'P' trap goes dry or 'air admittance valve' should stick open (small vent device on sink to tank drain line just after 'P' trap)
Until you open the underbelly cover ( 3 sided window) and locate WHY water was leaking out/fix that problem) you need to either leave the galley tank drain valve open OR dump tank frequently so that MORE water doesn't leak into underbelly.
