clooged sink

Is your grey tank full?Are you pulling the right valves?

My grey tank is hooked up to sewer and water is flowing from all other sources. Not sure what you mean by valves. Thanks

Maybe a stupid question but is this a new RV.
Do you have more than 1 gray tank?

on some of those models there is a galley tank the handle will be behind a wheel next to the belly

It's a 2012. I've put about 27k on it. Just one grey tank.

there has got to be another tank i have done so many service calls on this and everyone was a galley tank they did not know was there

I really don't know what a galley tank is. Where would it be? What is it's purpose. Thanks

You really need to get your manual out and educate yourself on the workings of your RV. YouTube is also a good source.
A "galley" grey tank is just that, it holds the waste or "grey" water from your kitchen sink. You may have separate galley and bath grey tanks or the kitchen may just dump into the grey tank for the bath.
It sounds like you need to empty what ever tank you have.

Lets start all over.........

Kitchen sink clogging.......but 'P' trap clear and snake down 6' clear.

So what do you mean by clogging?

When you go out to your 'service center' where you hook up city water, connect sewer hose and have dump valves for holding tanks.......how many valves?
Do you have a clear adapter (after market purchase) connected before sewer hose so you can see what/how draining is going when you open dump valves?

I'm assuming you are having backup problems in kitchen sink cause grey tank is not being drained and is full......over full.

Galley..that would be a second grey holding tank that kitchen sink (galley) only drains into and will have it's own drain valve. Usually within close proximity to kitchen sink (outside)......so IF and big IF you do have a galley that valve might be in another compartment separate from service center.

Get a different snake to go beyond 6'.
