  • Grey water question

    Posted by Roy on January 30, 2020 at 9:41 pm

    Then you are parked for 2-3 months (winter in Florida) does anyone create a P trap with their sewer hose and block open the grey water drain valve?

    I have see some do this by putting a block of wood under the dump hose creating a high enough hump to work the same way. Just be sure that you leave ONLY the grey open and to close it up a day or so before you are ready to dump your black so you can get a good flush.

    Why would you need a P trap in the hose?

    All fixtures and devices in the coach should have their own P trap to prevent odors and it doesn’t matter if odors get into the holding tank because it already stinks.

    RV Sewer Flies and Gnats
    are most attracted to the black tank, but the gray tank is also a home for these pests too. Once they get into one of your tanks, getting rid of them is very difficult. They will actually traverse the plumbing and end up in your coach. Bottom line, just keep both valves closed.

    Jon,

    in our arid climates, left used appliances, say W/D, “P” traps dry out. As well a driving in heavy Wyoming winds, which can suck the water out of your “traps”, we do create a sewer hose trap with a piece of something to “kink” the sewer hose to hold previously dumped tank water. Never heard of sewer gnats, tho. We just do this to prevent sewer vapor from ground connection being sucked into Coach tank from breezes blowing over roof vent by vacuum

    I have a single tank, but if I had split tanks I would still keep the valves closed and dump black first and gray second just to scour the hose. With the valves closed no need for a kink or trap.

    Ditto on the sewer bugs, they’re a bitch if you get them in the tank. I actually had some come out the lavatory sink overflow.

    Did i understand your comment? You have only one tank, no separate tank for gray and black water?

    Is this because the petal dispenser injects petals into tank to infuse contaminants diffuser?

    Why don’t other converters adopt a petal dispenser and eliminate dual tanks?

    All joking aside, I really like the way Liberty has the ONE holding tank setup. We have a separate grey water bypass if we want to use it.

    As we all know, the black tank needs a good bit of water and having one tank solves that issue. You can put more into ONE tank than into TWO. The rose petals don’t take up a lot of room.

    If allowed, we can release water directly on the ground or connect a hose to the bib and run the hose to a tree, etc. It’s a nice option.

    We also have the genius of Liberty’s single tank, grey water bypass, and rose petal dispenser. Love all of it.

    I have had a two tank set up and on the last 2 coaches a single tank.

    By far the single tank is the easiest and makes the most sense for me. If I am allowed and trying to extend the tank capacity I use the gray water by-pass. But that is rare.

    Most of the time when I need to refill my water tank the holding tank needs to be emptied so I do both at the same time. I never ever add water without dumping and I don’t have to wonder if one holding tank needs dumping first.

    Why the shock concerning a single tank design?

    You’ll love your single aluminum tank until it starts to leak, then you need to have Jeff on standby.
