Dumping the RV holding tanks is a nasty little job, but it’s part of the fun of traveling around in an RV, and we’ve all gotta do it. It’s really not all that bad when it’s a shared job, but of course that’s easy for us gals to say, because it’s usually our male partners-in-love-and-life who get to do the bulk of the dirty work.
Sometimes, when we go to an RV dump station, I am amazed to see a woman remain in the passenger’s seat of her truck or motorhome for the whole duration of the job. I’m not sure how these women have negotiated that arrangement with their significant other, but I figure they must be incredibly good cooks to be able to chat with a friend on the phone or check the latest on Facebook while their hubby is grinding it out with the sewer hose, the splashing water, and all that muck and mire.
I wish my skills were so awesome in the kitchen that I could be exempt from doing anything at the RV dump station. But alas, in our marriage, I need to be a participant in this dirtiest of deeds to win brownie points for other aspects of our life together. Nonetheless, it took me a few years to find things to do while we were at the RV dump station that were truly useful and helpful.
Too often at the beginning of our RVing lives I found my best efforts to help with setting up the RV sewer hose or screwing in the water hose ended up with me underfoot and in the way of the general flow of things. Mark had his methods, and I couldn’t read his mind as to what came next.
Few people are in truly sunny and radiant moods when they don their rubber gloves at the RV dump, and too often I found that my most valiant attempts to be helpful resulted in tensions rising between us.
Then one day I discovered a way that I can be of significant help and get some important jobs done at the same time.
GIVE THE BLACK TANK A BOOST FLUSH
For starters, I fill two 5-gallon water buckets with water and carry them into the rig to dump them down the toilet after the black tank has been emptied. Even if an RV has a black water flush system like ours does, it is still surprising just how many little bits of gunk and human waste solids get flushed out when two 5-gallon buckets of water are poured down the toilet.
I fill the buckets while Mark gets the sewer hose out and attaches the clear elbow so he can see when the holding tanks are fully drained. Then I can scoot out of the way and carry the buckets around to our RV’s door before he begins attaching the black water flush hose between the rig and the water spigot. This way we don’t end up stepping on each when we first start working at the RV dump station.
The buckets are heavy to carry around to our trailer’s front door, but I don’t mind a little bit of a shoulder and arm workout, and I take them one at a time. Maneuvering a heavy bucket of water up stairs is excellent exercise for both balance and strength.
I grab the inside of the doorway with my left hand for extra balance, tighten my abs so I don’t throw my back out with the uneven weight distribution of carrying a heavy bucket, and I leverage myself up and set the pails down inside in the kitchen.
For those who can’t carry the buckets, your partner will likely be happy to carry them for you since this really helps ensure the black tank and toilet get a complete flush. Also, filling the buckets only half way or three quarters of the way can help not only lighten the load but keep the water from splashing all over the place and all over you.
CLEAN THE BATHROOM
The other task I tackle is cleaning the toilet room from top to bottom and cleaning the bathroom vanity and kitchen sink. I figure that if my sweet hubby is dealing with the darker side of RVing outside at the RV dump station, I can deal with the same stuff on the inside..
This insures the bathroom gets cleaned on a regular basis and also means that when we arrive at our next campsite not only are the holding tanks empty but our bathroom is sparkling clean and smells fresh.
So, once I get the water buckets inside the rig, I begin assembling the things I will need to clean the toilet and the bathroom. When I hear Mark’s knock on the wall, I know he has finished emptying the black tank and it is time to dump the buckets of water down the toilet.
Since the buckets are just inside the RV door, it takes me a minute to grab one and empty it. Then it takes a few minutes more to go grab the other one and empty it too. Having a few minutes between flushes is helpful because then Mark can monitor whether the water from the second bucket is running clear or is still flushing solids out. If there are still chunks coming out, then, depending on whether anyone is waiting to use the RV dump after us, I’ll fill another bucket or two with water and dump them down the toilet.
Sometimes I have the water pump turned on as I dump the buckets of water down the toilet and sometimes it’s turned off. Having it turned on means even more water flushes down, which is great, but it also uses up water from the fresh water tank. So, whether or not I have the water pump turned on depends on whether there are people waiting behind us at the dump station, as it will take a little longer for us to fill the fresh water tank if we flush a few extra gallons down the toilet as part of the dumping process.
Now that the black tank is completely flushed, Mark begins emptying our kitchen gray tank. We have two gray tanks, one for the kitchen and one for the shower. We empty the kitchen tank first because it is dirtier and has more things in it (like broccoli bits) than the shower gray tank which is just sudsy water.
While he works on emptying the two gray tanks, I get to work cleaning the toilet.
Since we have a hatch in the toilet room that we leave open a lot, the toilet lid and the floor often get dusty in just a few days. So I remove everything from the toilet room and clean everything, including the floor.
Over the years we’ve found that the toilet bowl — more so than the black tank itself — can be a big source of foul odors. Unlike household toilets, RV toilet bowls are basically dry except during flushing, so urine can end up drying in the bowl and producing an odor.
Also, the flow of the flushing water doesn’t necessarily rinse every inch of the bowl, so some areas simply don’t get rinsed all that well, even when using the toilet’s spray nozzle. So, I go to town on the inside of the bowl as well as everything else.
We use two enzyme/bacteria based RV holding tank treatment products: Happy Campers RV holding tank treatment has worked best for us in extreme temperatures (very cold and very hot) and for controlling tank odors. RV Digest-It holding tank treatment has worked best for us in moderate temperatures to break down the solids in the tank.
Because these are both basically solutions of living critters, the toilet cleaning products we use can’t be too toxic or the colonies of feces-eating bacteria can’t get established and become self-perpetuating. I’ve been using Murphy’s Oil Soap for the last few years with good results.
This is the soap that is recommended for cleaning the rubber roofs on the tops of RV’s, which is why we had it on hand to try on the toilet a few years ago. In addition to being biodegradable, what we like about it for cleaning the toilet is that it assists in keeping both the seals in the toilet bowl and on the black holding tank valve lubricated. I used white vinegar for cleaning the toilet for a while, and after a few months the black tank valve got really sticky. Since switching to Murphy’s Oil Soap a few years ago, that valve hasn’t gotten gummed up.
Periodically, we’ve found the seals in the toilet bowl have stopped holding water which meant the bowl drained completely dry between flushes. This allowed foul odors to come up from the black water tank. This problem is usually due to mineral and gunk build-ups on the seal.
So, I give that seal a really good cleaning too. The critical areas are on both the top and bottom surfaces of the rubber seal, that is, between the seal and the toilet bowl (the top side) and underneath the seal where the dome flapper (the “waste ball”) closes up against it.
I make sure the water pump is off at this point and hold the toilet flush lever down so I can get at the underside of the seal.
Often, the build-up is due to having hard water in the fresh water tanks which is very common in Arizona and other western states where the fresh water comes from deep, mineral rich aquifers.
At this point, depending on what Mark is up to outside, I’ll move on to other cleaning projects. If we have nearly emptied our fresh water tanks prior to coming to the RV dump station, it may take 10 minutes to refill them. Also, sometimes the potable water spigot is a little ways beyond the waste water dump area, requiring Mark to move the whole rig a few feet forward.
So, if there is time, I will clean the bathroom vanity sink and then move on to the kitchen sink. Depending on our plans for the next few days and depending on how much time I have at the RV dump, I may also add the holding tank treatment to the black tank, via the toilet, and add it to the gray tanks via the bathroom sink, shower and kitchen sink.
Sometimes, however, I prefer to wait two or three days until those tanks have some liquids in them before adding the holding tank treatment. And sometimes I add just a half tank’s worth of holding tank treatment at the RV dump station and then add the other half a few days later once the holding tanks have become partially full.
Of course, we add a capful of bleach to our fresh water tanks every few months, and that totally obliterates any colonies of anything that have started to grow in any of the holding tanks (including the fresh water tank) as the bleach water works its way through our plumbing system from the fresh water tank to the gray and black waste water tanks.
So, for us, creating fully self-sustaining communities of healthy organisms in any waste water tank is not 100% doable. But by using non-toxic cleansers we can help them along in between bleach blasts.
So, all in all, there is a LOT a girl can do at the RV dump station. We find we are both much happier about the whole process when we each have a set of tasks to do when we get there that are not only similarly grungy but are equally important and that take place in different parts of the RV.
The best part is that when we leave the RV dump station to go set up camp in a new, beautiful location, not only do we have empty waste water tanks but our bathroom is clean and fresh too.
