RV Popup foldable camper exterior sink drain coleman

You are bidding on one homemade non OEM exterior popup camper drain.  The first picture shows you how I use it, the second picture shows you the measurements. We have a 2005 Coleman Bayside popup camper.  Like most Coleman popup owners, we have had issues with our interior kitchen sink draining.  Basically what is causing the problem is a lack of venting for this drain.  I have made an item using PVC tubing and garden hose attachments that will provide additional venting to this line just beyond the exterior elbow that is used to connect the drainage hose.  I have been using this item for the last few months and I can honestly tell you that our sink now drains at a normal quick rate.  We have had no slow drains whatsoever.  My wife loves it.  Having said that, I cannot guarantee that this item will work with your popup camper, but from what I have read on quite a few forums, installing an exterior vent for your drain will in most cases solve your problem if you are having sink drainage problems.  As you can see from the pictures, this item has a female garden hose attachment that connects to the exterior elbow drain and then it has a male garden hose attachment at the lower end for you to connect your drainage hose.  I suggest you set it up at a slight angle as I show in the picture, this seems to allow more air to mix with the water as it drains.  The item you purchase may have some stamped ink writing on the tubing as these pieces were picked up at a local plumbing store.   If you have any questions concerning this item, please feel free to ask. 

I have placed a Youtube video online to show you how this item works in my coleman popup camper, if you would like to check it out, please go to this link:  http://www.youtube.com/watch?v=fTsAmZxC3KQ

I have sold several of these in a previous ebay listing( ebay item # 160617312565) and everyone has been pleased with their purchase.

Here is a message I recieved from a purchaser of this item:

Dear toshlito,

We have a 2008 Fleetwood E2 That the sink has never drained well, fair at best. We used your sink drain vent last weekend while camping & it worked great! Camper sink now drains like our household sink. I was trying to figure out how to put a vent in the drain when I found your vent on ebay. Thank you for the excellent product.
