Honey wagon question

So as not to high jack another post, I'll ask my question here.

I'm reading to my DH about honey wagons using vacuum to empty RV holding tanks and tanks possibly being damaged. He says it can only work with vacuum since the truck tanks are higher than the RV tank. Otherwise the RV tanks will not be emptied. How do they work?? Do they use a pump of some sort vs. vacuum? We've never used a honey wagon service.
  • The safest way to do it is to slurp it out of a bucket.

    Otherwise...lay the sewer hose out on the ground. Have the service man pick up a couple of feet of hose, insert his suction wand and pull his valve part way. It can't get enough suction to collapse a tank etc.

    You pull your sewer valve part way. The trick is that you don't overrun the suction wand.

    I was taught this by an old-timer in north Georgia; we could slurp out tanks in a minute or two complete with water rinse as possible. My cut was $10 per tank plus a freebie for me.

    every rv has atmospheric vents from the waste tanks. There are no one way (check valves) valves that could permit a vacuum while the tank is being suctioned.
    Your tanks and piping cannot be damaged by a pump out service unless you block the vent.


    This.



    Absolutely incorrect.....

    I have 30+ yrs of DIRECT involvement with 'Vacuum' and personally know what is necessary to establish vacuum and what it can do.

    Even with a fully functional 1/1/2" vent line a small vacuum pump can collapse a plastic waste tank.

    Why do you think 'opening the toilet flush valve' is recommended when using a pump out service?

    To provide an additional source of venting (which is same size as drain line)

    Check out this post made yesterday.

    Is that the post you didn't want to hijack? Short answer, yes, they must use a pump. It's going to depend on the particular service you choose as to how 'much' pump that'll be. There seems to be a disagreement in the linked post as to whether the vent will handle it. Black tanks drain pretty fast on their own, so I'm not quite sure why these guys have to use such powerful pumps.


    They run the pumps as slow as they can. They do use these wagons to pump up "goo" from many feet below then, ie septic tanks and such, so they do need powerful pumps to do their job.

    How about holding open the toilet valve when emptying? This would give LOTS of air to the Black Tank, and also have an opening in case the vent was plugged.

    :S
    How about just making the lazy septic tank drivers do it the CORRECT way to prevent damage to your RV?

    I guess the choice IS yours if you like standing there watching a process that will damage your RV.

    That would be much easier than trying to explain to a lazy septic tank driver how to do his job properly.
  • I'm often puzzled by the number of "lazy" workers that some people seem to attract. It seems like they are consistently burdened by these "lazy" folks that are hired to do a task they don't want to do. The solution may be to hire and train their own, personal worker that is highly skilled in a number of tasks. That way, they will know they are getting service from someone that is adequately trained and is motivated to their own specific level of industriousness.

    Here's the problem with that. Not everyone is a full timer, and the dump schedule may be when your gone.

    Our CG dumps on Sundays and Thursday's. Most of the time I'm long gone before they get to me. Very few CG's dump at the campers convenience.

    If you are not there to 'hold your toilet open':R to prevent damage to your RV then what? Not to mention the sewage stank that will fill up your entire RV while you stand their holding open your toilet that has NO p-trap.

    The original OP on the original post stated he HAD 'damage' done to his RV.

    Forum members explained how/why the damage occurred.

    Yet some still want to try and adjust, hold open toilets, etc, etc to accommodate the 'incorrect' way a septic company is 'draining' their holding tanks.?

    The septic company is contracted by the CG. If no one tells the CG owner how this company is incorrectly draining the holding tanks that can and will cause damage it will never be rectified. Then IMHO you'all probably deserve to have to repair damaged toilets and cracked tanks. Just saying have a nice day. :C
