Slow Drain

[mjdfarm]

Any suggestions to remedy a slow sink drain in a 98 coleman?  I have seen vent systems and larger drain hoses.  What works best?

Its not obstructed just slow....

The easiest way to get it to drain faster is to lift the galley a little bit and shake it.  Not always possible.  I have installed a vent and that has helped.

Yes with 5 of us in the camper our galley is usually full of stuff.  I am considering building a vent system out of pvc.  I was hoping maybe somone had a photo....

I may have a picture in my webshots account.  If not I can get the pieces out over the weekend and take some pictures.

I checked your photos but did not see one.  Ill check back this weekend.  Thank you

The first thing to do is look at the tubing from the sink to the wall connection. the vast majority of slow drains have a droop in the tubing which forms a second trap. The fitting in the base of the sink includes a trap so the second one causes quite a slowdown.
The next "fix" is the outside hose. Again if it droops enough to form a low spot that can fill with water you have a second trap that again will slow down draining.
And lastly make sure there is some kind of venting on your gray water container. If the air can't get out, water can't get in. The air will be displaced back through the hose to the sink to allow romm for the water and so again slow draining.

Thanks Mike I will check for these things.  I never thought of the double trap issue.  I thought it was a vent issue at the fitting coming out of the camper....

That is where my issue was.  I don't have the double trap issue.

I went to ace hardware and bought pvc fittings to attach to the sink drain to vent the drain.  Working with pvc is like putting together a puzzle.  We will try it this weekend at Florida Caverns State Park this weekend.  I will let you know how it goes.

Here's the setup I've gone with.  
 
 original setup:
 
 
 After realizing I quickly fill up the 6 gallon grey water tank, I decided to pickup another 6 gallon tank so I split my connection to give me twice the storage.  The valves allow me to turn on and off each tank so they can be dumped

That is the same setup I concoted (minus the split).  Im glad to see it actually works for someone.  Thanks for the great pictures.  Ill let you know how it goes.

Hello, My neighbor has a 98 niagra and he has the same problem. When you lift the galley slightly, the drain empties. The elbow at the drain has a trap in it. My 99 sunvalley just has an elbow at the drain (no trap). Perhaps there was a common problem with these drains and to "remedy" the problem, Fleetwood removed the trap at the drain. Just a thought.

Actually your right why is a trap necessary. I could see having one when hooking up to a sewage line where you can actually get sewage gases making its way through the plumbing back into the trailer but when connecting to a  couple of gray water tanks does it really mater.

Your dealer may have removed the trap, but Fleetwood certanly did not.
