Has anyone else noticed a problem with the sink drain (main sink next to the stove) not flowing well? I took off the trap and everything is clear. It appears there might not be enough change in height after the trap to generate good flow. Would shortening pipe going to the gray water tank help? Thanks!

Have you done the "Grey tank vent" mod yet?  That seems to cure the problem and it's a simple and easy mod.

I'm with Neal. venting. You can get an air trapped bubble just below the drain....just for the heck of it wile it is draining slow take a popsicle stick or similar and try to break the air bubble just below the sink drain opening

To Joe, there is a plate just under the drain. Liquid goes down and around it, I suppose to prevent objects from going down. I prevents me from inserting anything down the drain.

 

To Neal, what is the "Grey Tank Vent" mod?

 

Thanks gents!

Here is a link to one example.

Just happened to think.....  does the bathroom sink drain easily? Just wondering if your gray water tank is full....... Can't find the capacity for the 13' trailer but I'm sure it is much less than my 17'.

Not sure what year his 13' trailer is but my 1994 13 footer had a 13 gallon gray tank and a 9 gallon fresh water tank

It's a 2014 13'. Bathroom sink drains fine and gray tank is empty. I even had drain valve open and cap off hoping to create equal pressure from sink to outside. It was still stopped.
After I took took the trap off (which was clean) and put it back on, I ran water and sink drained. I'm going to try Joe's approach and see if there might be an air bubble being created right under the drain in the trap. I'll see if I can get a flex tie down in there when it stops up.

It's going to be an air bubble because the vent tube is pretty far from the kitchen sink as opposed to the bathroom sink..... to me it's no big deal as my 17' model does that in the kitchen.... so i either poke it in the drain with a thin object or just don't turn the water on strong enough to make air bubbles form just below the sink screen.....simply turning the faucet so it is off to the side will also eliminate the air pocket

My little buddy is parked up in the woods so I won't get to try this out until next weekend, but it sure sounds like the explanation and the solution! I'll let you know. Thanks, Joe!

okay.... first off try turning the water spigot off to one side and run slowly so not to  gurgle in the drain and i think that will do it.

  Let us know as others may have noticed the same thing

 

My post above i stated a 1994 13 footer but i mis typed as it was a 16' My 2010 13' model did that... my 16' had the vent mod.

 The 13' and 16' model is a little tougher to do the vent mod because of an angle iron getting in the way which makes a dip in the line that could fill with water.

  there is a way to remedy it and will explain it if need be
