    I have researched this on the site, but wondering if this would work for me? As you know sink drains very slowly. My pup has the drain underneath the camper. Has a hose bib type connection so you can attach a garden hose for gray water. Why can't I just put in a tee fitting under the sink with a hose (same size as the sink drain) and take this up to above the level of the sink. Attach it to the counter top just like your home kitchen sink? All it needs is an air relief for it to drain quickly.
    Your thoughts?

    There are two main issues with slow drains in PUPs.

    The first is the 'lay' of the drain hose under the sink. It needs to be a continuous downhill run to the drain on the wall. Many times, it gets kinked up and ends up with a 'high' spot where gravity starts messing with you and slowing things down.

    The second issue is the lack of a 'vent'. An easy mod is to build a vent stack that goes on the outside of the camper. This will speed up the draining substantially. Here is the one I built a few years back:

    Our Coleman Mesa's drain is also under the camper (drains through the floor)and we've never had a problem with a slow drain. The only time it had drained slow was when I forgot to remove the vent screw from the gray water jug.

    I would check the routing of the drain pipe to make sure there aren't any kinks. If it's a new to you camper I would also consider the possibility that there may be a clog from the previous owner.

    I saw this when I searched, but mine is npt this type. it drains through the floor to a hose connection underneath as I stated before. There are no kinks in the line and is not plugged. needs an air gap. thanks
