I am looking for input, suggestions, experiences etc. Pro and Con for using a separate black water from grey water tank vs just one tank for both. Also any suggestions on venting the waste water tank Thanks Les | ||

We have just the one 100 gal. tank for waste and gray. I don't know why some use two tanks and have no experience with that. I like having one tank to help flush out the solids. Ours is vented at the top, rubber hose running down the side to underneath the bay. It seems to work for us, so no need to change it. | ||

2 tanks are the norm with one tank you take more risks being exposed to Hydrogen Sulifide or Methane gas P traps splash all the water out from the drains when traveling with 2 tanks the black tank is the only place where Hydrogen Sulifide is present and the toilet water seal and vent takes care of that. Everybody does it different and it works for them I just never took the chance after seeing a methane expolison it was always 2 tanks for me (Message edited by luvrbus on September 16, 2010) | ||

I would go with one tank, simple. Although 2 tanks allows you to dump some grey water here and there if you can. JC | ||

I don't have "bays" on my bus and underfloor volume is very limited. I want about 100 gallons of fresh and there's room for an underfloor tank no bigger than 70 gallons; for this reason, I'm putting in a 30 gallon grey tank with an "overflow". After used washing water fills up the grey tank, it will overflow into the underfloor tank. When I've used 50 gallons, the grey tank will be full and the black tank will have 20 gallons in it. When I've used 80 gallons, the grey tank will be full and there will be 50 gallons in the underfloor tank. When I've used all 100 gallons of the fresh, both tanks will be full. At that point, I drain the underfloor tank (which has a mixture of grey and "black") and then pull a flush valve that runs the 30 gallons from the grey tank down into and through the underfloor tank. Won't that "help flush out the solids", Paul? If I had room, I'd probably go with a single tank. But I don't have room so I have to use what's practical. Gary Throneberry found some really neat gauges from a company called WECO (my bus wasn't built with a fuel gauge so I had to add one of those, too); they're "marine" but no more expensive than parts from NAPA. They have different designs for fuel, fresh and grey water, and black water and I expect that they'll help me manage my tanks. (Of course, it would be pretty rare to wait until the tanks were absolutely full before emptying, but I'm just trying to be descriptive here.) | ||

We've had both, w/TempBus being a single tank & Pray-vo being the two, and hands-down I like the single tank better. We can go about a week on our tanks and we always fill the grey way more than the black, and I prefer more, um, well, like my investments, I want a certain amount of liquidity there, haha. As for sloshing water out of the traps, haven't had that happen in a bus...now that little class c we have....maybe more likely, but Larry's so smooooooooth, that, back in his service-tech days, he used to forget and drive all over town with his flashlight laying on the bumper of the box truck, haha, and it wouldn't roll off. All of our buses ride smoother than that old truck for sure! You could always use deep traps when plumbing, which would be my choice anyway, if this was a concern. We've never just let the grey drain, so I guess if you planned on doing that, you'd pretty much have no choice but two. With one, you don't have to try to figure out what goes where and account for the difference in usage between short trips & long ones, boon docking v.s. hookups, etc. Me, I got running water, it's a running shower & possibly a bath for me, limited water...well, I can go military style like the best of 'em!

we have 1 100 gal for bk/grey vented to the roof. between the dishwasher the clothes washer and 2 showers a day there's no competition with all that water and any little "fishies"..We are mostly at the dock with the valve always open. this way for 5+ years never a problem PS. If we didn't eat it, It doesn't get flushed (no paper,no plugs,no exceptions) Pss....All drains have traps on them When we do need to dump our tank we always run water down every sink and shower drain during the procedure to reduce the chance of any unplesant aromas (Message edited by steve wardwell on September 16, 2010) | ||

I also have limited under floor space. In my bus I will be mounting the throne on top of the black tank (with the black tank actually inside the coach) My thoughts on it are that the throne is then higher (which in olden age is always a good thing) and of course, it wouldnt freeze. On my prior s&s I had 2 tanks and liked it. The way it was set up is that the black was under the throne and the grey was under the shower. When the grey would overflow the shower pan would get water in it. The valves outside for dumping were set up so that I had choices. I could dump either the black or grey individually or I could dump the black and then have the grey water rush through the black to clean it out. Of course water can and should always be sprayed into the throne when cleaning out the black tank to flush it all out. The neat thing with this kind of set up as well is that I could always dump the grey most anywhere (there was also a nozel on it for hooking up a garden hose to dump the grey) I didnt have to drive around with the extra weight of grey water! When I stripped my s&s I took all this stuff to put into my bus. | ||

Code issues aside, and having had both types, single tank hands down. With two it is at best a guessing game to size them so they both end up full at the same time. Of course there is always plumbing the gray so you can dump it into the black if full but if you are going to do that why not just build one tank in the first place. There is the issue of black tanks not draining and needing to be 'flushed' with the gray, a problem you don't have with combined. If you have problems when hooked up with either system, close the drain valve and open when needed to keep things moving. Much less plumbing and venting. If you really think you will be someplace where you can get away with leaking gray, a diverter valve before the tank would be easy. Don 4107 | ||

We have a single 100 gallon combination tank. we do have a diversion valve on the shower drain that allows the shower to be drained on the ground, depending on our location. Since the shower is the largest source of grey water, diverting this to the ground allows about 3+ weeks without dumping. We also installed an auxiliary dump on the passenger's side of the bus as well as the standard dump on the driver's side. Buying one big tank is usually cheaper than buying 2 smaller tanks with equal capacity and less plumbing is necessary. Just "our way", YMMV Jack (Message edited by JackConrad on September 17, 2010) | ||

I can see were a 1 tank would work just fine but to me it looks like the bus people are the only ones doing it. In all the years owning a RV I never had a 1 tank system is there a standard for the RV manufactures to use 2 tanks ? they way those people cut corners looks like they would have one tank. I do it for safety and that only because building sewer treatment plant I do not like sewer gases of any type and using your fixtures I can see where the traps would stay full. I have had buses come to the shop where they been on the road for days nothing and has been used for several days and the traps are dry and it will gag you when you open the door and the people have got so accustomed to the smell they don't even notice it till they stop . I know on the later model seated coaches with restrooms those have a sealed tank with a power vent and a monitor for the gases. I'll stay with the 2 tank setup | ||

My TT has a 30 gal black & a 30 gal grey. I'm guessing they put in 2 tanks due to space resrictions. Not to mention the weight distribution issues that the light weight vehicles are more sensitive to. We're like Steve - if we didn't eat it, it doesn't go in there. We've never had an odor issue from the black tank & never rinse or use chemicals. The grey tank is the one with the odor issues. | ||

If you vent under the bus, you WILL have sewer gas under your bus & since it is lighter than air, it will travel up. So, there is a greater chance the sewer gas can find its way inside when it is under the coach than if it was already above the coach. | ||

It depends on your desired space use. In my Eagle 10 I put a 48gal tank in each OEM AC evaporator compartment for my gray water. It dumps by electric valve to the black which is in the bottom of the back bay. The curbside gray tank is my shower and vanity and I have a 3/4" valve to dump to the ground if allowed. They gray tanks dumping to my black agitate the solids and flush the black tank very well. Total is 96 gals gray, 58 gals black, 130 gals fresh water The engineering is pretty much your choice. I vented my street side tank and black tank with a 2" pvc pipe through the roof. The curbside gray tank is vented with a 1 1/2" pvc pipe through the roof. The 2" pipe has one of those venturi gizmos I got from Camping World that is supposed to draw the gases out of the tank while traveling down the road. House plumbing codes dictate a vent above the highest drain fixture in the structure and that it terminates above the roof and not under a soffit or eave unless it has an anti siphon valve on the vent pipe. I've seen those on some laundry room add ons where they couldn't get outside and up with a pipe. I would avoid going down if possible I'm not sure what applies in an RV. Someone with a code book may chime in with more expertise. David (Message edited by davidanderson on September 17, 2010) | ||

Kyle, we have probably hashed this out many times in the past but why is t you said, "you WILL have odors" if you vent under the bus? Mine has been vented under the bus since I installed my black/grey tank and NEVER HAVE had odors of any kind, sitting idle or travelling. Now I know MY stuff don't stink ([)) but what gives with the statement that it WILL if vented underneath? I know of a few that are this way and they claim the same. | ||

Tom; Shouldn't be problem because of 1/4" slope in drain pipe. I generally open black 1st and when it is almost empty I open Grey valve. Grey is behind Black and black has a 4 inch opening with twist screw in sewer cap on top which I put in Black hose and spray out the whole tank while it finishes draining. I also put in female hose connections at top of both tanks with clear hose connected coming out to face of bay and I attached to the plywood face. I can just hook up hose and clean both out until water run clear. I very rarely dump both at once unless in a hurry which is also rare. Also got a clear 45 degree bayonet fitting at Wally World that has the hose and anti-siphon valve built into it and you can shoot water up the 3 inch outlet pipe to clean it also. So ya we believe in clean and No odor. 2" vent out the roof with the tee cap. Dave | ||

ace, what I said was: "If you vent under the bus, you WILL have sewer gas under your bus & since it is lighter than air, it will travel up. So, there is a greater chance the sewer gas can find its way inside when it is under the coach than if it was already above the coach." See, nothing at all about odors. The fact is that the waste tank vents sewer gas. Logic leads me to believe that where the vent opens to the atmosphere, you will have sewer gas.  If placed in the right spot, the gas will dissapate with out notice. If placed wrong, the gas may collect in an undesireable location with unpleasant results. Obviously you don't have a problem with odors & probably have a tight bus, Glad yours is working well. | ||

This is one of those questions/answers that always has a "depends" in it (no pun intended). That you can see from all the different opinions and setup variations. I am mostly a weekend user of the coach with 4 or 5, week long trips each year. I went with the two tank setup. 100 gallon gray and 80 gallon black. Both tanks have seperate valves that feed into a common tee, the output of that tee has another valve that goes to the hose/dump connection. I dump the black tank first and then use the gray to wash out the tee/valve and the hose. Another reason for the tee set up is, if the gray fills up (which it always will first) I can move some of the gray into the black through the valving. I have done this many times while boondocking or where I didn't have full hookups. Anyway, this works great for us, maybe not for you. I have 120 gallon fresh on board. | ||

I want to thank all of you for your input on this issue. I have decided to go with one tank for both grey and black water with a top mounted manifold to rinse out the tank when dumping. I am still not decided on the roof vent or rolling the dice and going out under the coach. It is very tempting because it is a lot easier and doesn't necessitate another hole in the roof of the coach. I have the worst luck with roof leaks on our old s&s motor home. I have found some long, narrow tanks that will go almost from one side of the bay to the other. Because they are narrow I can put two of them across the rear compartment and still have room for the pumps etc. The rear baggage compartment in our 102 is only 38 inches wide at the door so to get two 120 gallon tanks that will fit is a big bonus. | ||

Folks, A few years back, when I was designing the bus plumbing, I read on this forum about folks venting under and/or in the engine bay to avoid poking holes in the roof. Good idea, I thought. WRONG! I have vents into the engine bay and many times I get smell in the bus. It happens that I also have the W/D in the back of the bus and often I can smell the fumes in and around the washer. I also have a Kool-O-Matic fan in the roof that pulls air out FAST. That contributes to drawing in the bad fumes. When I get really ambitious I will poke a hole in the roof and vent UP to avoid this problem. Do it like a house and it will work. BTW - I have 1x 200 gal combined Blk/Gry tank and would never dump just gray anyway. It's MUCH easier to deal with. Randy | ||

We have one 100 gal black and grey tank with a diverter valve on the grey pipe to dump it on the ground before it reaches the tank. We dump grey on the ground at home, friends places, and going down the road. In short, everywhere but campgrounds and paved parking lots like Wal Mart. I realize that it is terrible poluted stuff to the EPA, but then to them, the rain water that runs off the cabin & deck of a tugboat is "polluted". They need to lighten up. I'ts legal to wash your car or your dog on the grass, but not to allow your soapy shower water or hand washing water on that same ground. Billions of domestic animals pee & poop on the ground. Don't let the EPA get ahold of that or they will force farmers to provide facilities & document that the animals are using them! So many absurdities in modern life. | ||

Randy, You're the first person I've heard of to vent in the engine compartment? Air currents there are wild and unpredictable so I'm not surprised you have odor. Most bottom vents are through the floor, as is mine, with no odors. If you reverse your Kool-O-Matic fan it might solve your odor problem. Do you have a drain trap on your W/D? If not, it needs one. | ||

If done sparingly/ slow enough so that the water sinks into the ground long before it has a chance to stagnate, I don't see a real problem. The problem arises when the runoff creates issues for others. Kinda hard to know what's going on outside when you're in the shower . . . . Without a through discussion, some might think dropping the grey water is a task that needs no consideration of others. Here's hoping that everyone who dumps grey on the ground does so with full consideration for others who may be affected. | ||

Because I started this thread I thought I would let you know what I decided to do. I will use only one tank (120 gallon) for both my black and grey water. I am going to try venting under the coach because it will be so much easier but will have an eye for the possibility of changing it to the roof in the future. Part of the reason I want to avoid venting up thru the roof is to reduce the leak factor by one hole. Just a little confession. I have dumped grey water on the ground and once in an emergency I dumped black as well but it was in a very rough ditch and I had no chemical in the black tank..... Did have my mother in law on board. Again thanks to everyone for the input. It made my decision easy Les | ||

Les, I'm sorry. I got so caught up in my rant I forgot to mention the other half of my comment. Our combined tank is vented through the floor of the bay. It was done this way by the previous owner. If we are camping and the breeze is NOT from the "awning side" of the bus (passenger side), then we have odor as we sit under the awning. The tank makes fumes and they have to go somewhere. I will be converting ours when I can and I urge all of you to go up through the roof. You can use a lead flashing or a rubber one on the roof to seal the vent. I have one of the rubber ones on my house (metal) roof I can send a pic to if you want to see. It does not leak and it's been there for about 25 years. It is also easy to change if needed and it would allow you to use some kind of tee or "extractor" on the vent if you wanted to though you don't need one. | ||

OK Jim you have me rethinking my vent once again. I would like to see pictures of the seal you mentioned if it is not to much problem. Just a thought, where on your coach does the vent come out?

Les...I'm with Jim! I, too hate to put holes in the roof...a number of reasons, but for a sewer vent, I would do it in a heartbeat!!!...(use 2 inch venting for sure). A venturi cap is wise. PL for Roof Flashing is a great product, so is SikaFlex...you should have no problem with either of them. I have three 6 inch "skylights" in my roof sealed with PL. No problems in 9 years. Even with a rubber gasket, I would use it. FWIW. RCB | ||

I found the sewer 2 inch vent pipe a really EZ way to lead the output from the solar cell into the coach. The Trace controller is in the head , so multiple times a day its easy to keep track of how the batts are doing. NO,, a bunch of lights showing simple voltage is not a substitute for a good SOC meter, but frequent checking can't hurt. If you have to knock a hole in the roof (as required for a NO STINK coach) simply use the hole as many times , for as many purposes as you can. FF |
