There should be a big trap in the sewer line just before it exits your house
My home on city sewer and my cabin with septic does not have a main line trap . If you place a trap at the fixture and in the main line you will be double trapped and that is illegal in most areas and unnecessary. The waste water on a trailer is only trapped at the fixtures ( sinks , shower ,toilet ) and not at the tanks. There is often a back flow preventer on the main sewer line to stop sewage from flowing from the main sewer in the street back into your home
Years ago the used what was called a running trap.

Last year my campsite neighbor washed their dishes at the back of their RV and then dumped the water in the bushes a few feet behind us.. even though a very nice dish washing station was at the bath house all of 50 feet away from them!

My house, built in 1958, drilled well and septic tank, has cast iron sewer pipe in the basement and out to the 1000 gallon tank. There is a trap at the basement wall where the cast iron goes through. Please don't call the sewer police on me.

Interesting you said that. At the LBL rally last October, I asked at the ranger station if there were a place to dispose of water used to wash dishes. After giving me an incredulous look, he said "Ya, in the bushes behind your Campsite.

Let me elaborate lol. If one showers in the campground shower and washes dishes and hands in a sink bowl then waters the trees when bowl is full then the 32 gallon gray tank stays empty.

On to the toilet and if it is only used for #1 ONLY but has some TP in it from the wife (sorry if I'm too much info but it's needed for the subject lol) then on a long trip the 8 black gallon tank can fill fast.

So if I pull both valves then essentially the black tank will drain into the grey tank. Then we can empty the black 5 times before dumping. This is due to gravity with black tank higher than grey. I realize when I do eventually drain that some will spill out as soon as I uncap.

What's the consensus? Is this crazy? Will the TP cause an issue sticking in grey tank? What am I missing that makes this a bad idea? The only thing I can think of is maybe it's a better idea to put the tp In a trash can to keep everything 100% liquid. Have u done this?
First thing is please don't put water that you have washed your hands in or dishes in on plants. It is illegal in 99% of the places I've been. If caught you can be fined. It seems like a good idea but it causes a smell, can damage plants and also attracts bears and other animals. There's soap in the water. Second never put black water into a grey water tank. The reason the hole for grey water is smaller is because it is for water only. The black water is for solids and paper, etc. If you throw paper into a trash can think of the bacteria, etc. you are putting into your trash and that is in your trailer. You are thinking but it's a poor idea.

I would guess from your post that taking a bath in the lake is out ? and thanks , now I know why my trash gets sick , I've always wondered .
In my area the people who pump septic tanks , legally spread the waste out on fields so it breaks down naturally , so I am not worried about a little bit of wash water getting spilled on the ground..

I have LOTS to reply but I won't!! Thank you to those that understand!

I must say tho I completely dont get how my original post ended up as using my FRESH water tank for grey or black then switching back. That was NEVER stated nor an option. Thanks for letting me know not to do that! uuuggggg

I think I'm done with this thread. I will think 3x before posting again. Thank you everybody for your replies! If a moderator is reading, this entire thread can be deleted LOL.

You asked for opinions and you got them.
If you don't like them, don't read them.
Meantime, others are having a discussion.

Joe, your question was fine and I've never seen it come up before and was answered by many early on. It was pointed out that some builders do use one tank for both. Like tires, TW, bearings and such, some threads seem to go a bit sideways . Hope none of the mods delete all of it, or a least leave your original question/responses, someone else may have the same thoughts.

I would think that a problem would arise where the liquids would drain off into the gray tank, leaving a mountain of solid waste in the black tank, unless useing alot of water while flushing.
While working in a campground, Housekeeping would make mistakes and leave the black water tank valve open, on a rental unit, and maintainence would have to go in and break down this mountain of waste with a stick and lots of water...not a fun job.
Also my gray tank has only an inch and half outlet where the black has a 3 inch outlet.

The National Forest in Maine and New Hampshire will not let you wash dishes of self, at or near, the potable water pumps and tell you to wash at your site and throw water into woods.
The Question is, if it ok to throw this water from a wash basin, why can't I just let it flow out the gray water hose?

If that is a true statement, then I would conclude you haven't been in many places. And I will have to start wearing latex gloves when it rains for fear of rain water dripping off of my badly contaminated hands and landing on the pristine ground that birds and other wildlife never sully with their feces.

I do understand your question, and I would tell you that it is your trailer, do as you wish, although I would personally get a blue tote. That way you can dump whenever necessary. Even if you were to combine your two holding tanks, fresh water obviously excluded, at some point in time they would fill up and require dumping.

What I don't understand, or condone, is your response. As Glenn stated, you asked a question. If in doing so you open up a can of worms, the worms are going to get out. Some people may please you by baiting your hook, while others will simply refuse. This has been a good discussion with lots of varying opinions, some biased, put forward. It is your right not to post again, but I perceive that approach somewhat the same as when an adolescent doesn't get his way and announces that "it's my ball and if you won't play by my rules, I'm going home." I also perceive that the "negative" responses have hurt your feelings somewhat. I surely hope that you don't believe you are the only person on this forum that has ever felt "persecuted." It happens all the time. The vast majority of people here are NOT malicious. They only state their opinions on topics that arise. Just because some are "passionate" in the way they respond doesn't mean they are right or they are criticizing you for your question.

I totally agree and apologize. I think I felt a little piled up on and many even took my original question and added to it like the fresh tank comment or people talking about solids. We have never used our rv for going #2. So when it got further into doing things I never even asked or intended I felt piled up on, or had an "I give up" moment. Anyway I agree my reply was wrong. And yes, I did ask! Please don't delete this.

I must also add we are probably the most respectful camp neighbors you would have. I would never dump food out period, or even a pan of dish water close to anybody. We have septic at home and know food gets scraped into the trash before dishes washed. If I were to dump a pan of dishwater out it would be in a remote area. Most of the places we camp are rustic and rural, not concrete jungles all packed in.

Anyway again I apologize to all for my short remark. And thank you for your thoughts!
