Midbath March 15, 2022, 02:49:02 am While trying to learn the pros and cons of each model, and reading old posts, a new question came:Since the Midbath has two different valves (one for the gray tank and one for the black tank) is it harder to keep the sewer hose clean?
Re: Midbath Reply #1 – March 15, 2022, 03:05:03 am No. You just do the Black and then move it to the grey. I now have a class A with both valves dumping into one outlet. So it is a very marginally bit easier because you do not have to move the hose. But I never found that a problem and the plumbing is much simpler if something goes wrong. Just an opinion. 2 Likes
Re: Midbath Reply #2 – March 15, 2022, 03:36:50 am Hi, Sam-When you visited, I'm sorry we didn't go around to the side with the dump. There are two different valves but only one sewer hose hookup on my 2003 RK with a mid-bath. Hook up the hose, dump the black tank first, close the valve, then dump the gray tank. The water from the gray tank somewhat cleans out the sewer hose. When I unhook the sewer hose, I then rinse it using a dedicated garden hose. I definitely would not want to move the sewer hose after dumping just the black tank!This is my third RV. All three had the same system: two valves but one sewer hose hook-up.-Judy 1 Likes
Re: Midbath Reply #3 – March 15, 2022, 08:32:41 am The cleanliness of the best dump station must be a collection of unimaginable nasties. Without any exceptions, I wear latex gloves while dumping. But wait … there’s more. After rinsing the dump hose, I spray it and the ground connector with a disinfectant spray. And I give the soles of my shoes a shot of disinfectant too. We simply want to limit as much as possible introducing those unimaginable nasties into our home. And that’s our dump station routine. 4 Likes
Re: Midbath Reply #4 – March 15, 2022, 12:32:44 pm Always dump the black water tank first then do the grey water as it flushes out the hose. Also, do not leave your hose hooked up, it provides a path for critters to enter you rig and is less smelly. 2015 MB, Silver Fox SeattleIan Walkerianwalker858@aol.com 1 Likes

I love the people that dump in their flips!!! Yuck!! They need to spray bottom of feet. Spray on shoes is good idea. I usually change shoes. When camping with the kids I was amazed how quiet they were during dumping….guess they didn’t want to be drafted for helping with the dump!! Hahaha 2 Likes
Re: Midbath Reply #7 – March 16, 2022, 10:14:22 am just a couple more tips to ensure sanitary conditions apart from the ones above:to prevent poopsies, make sure all sides are properly connected. phonically touch each of the four round parts on the end of the hose and ensure that they are inside the hook on the RV connection. it may appear connected when 2 or 3 are good, but a fourth one can make a mess!to make sure the hose is not nasty when moving between black and grey: close the black tank, fill the toilet bowl with water and flush two times and then open the black tank again. I do this twice and on the second it just has water coming out.
Re: Midbath Reply #8 – March 16, 2022, 10:56:16 am New (and not so new?) RVers might want to look at a venerable collection of RV wisdom called "Phred's Poop Sheets". Phred Tinseth passed away a few years ago, but his advice lives on at this site:Macerators and Other Sewage Stuff by phredThe link above deals with RV sewage. Other sections of the "Poop Sheets" contain a great deal of basic, still-valid, relevant information, but some of the information, e.g., solar, communications, etc., is outdated. I suggest reading the entire collection, then checking additional credible sources for currency of information, equipment, products, etc.YMMV, as always. 2 Likes
Re: Midbath Reply #9 – March 16, 2022, 02:51:12 pm SamOne of the few drawbacks to the MB in my opinion is having two separate valves for the waste. I use a clear elbow with a hose attachment. After the black tank I rinse the inlet, close the valve to rinse the out side then drain the sewer hose as well as possible before moving on to the grey tank. Bit more of a hassle but doable.Ken
Re: Midbath Reply #10 – March 16, 2022, 07:32:25 pm It takes a little longer, but I follow some advice I received when I first got my motorhome. I always use see-through fittings on both ends of my sewer hose, and first fill the black tank with water and then after dumping it, I refill it with clean water at least once and dump it again until all the flush water runs clear. I don't have to guess if it's thoroughly cleaned. The gray tank gets dumped next and then the hose washed out with clean water. I do have a hydro flush fitting too, and for the MB that works best on the gray tank. For ten years, using a good enzyme there's never been any smell at all nor any problems. Did replace a sticky valve though. So far, so good.Kristin 4 Likes
