The Waste Treatment Tank (The Black & Grey)

I do not plan on explaining how to dump the grey and black tanks on your RV.  What I would like to do is to explain how to stay out of trouble in dumping your tanks and dis-spell some of myths on when to dump your tanks.






So what is the main differences between a sticks and bricks waste disposal and your RV.  First there is no worry about getting rid of the waste at your sticks and bricks.  You let water splash into the sink and it just disappears down the drain.  No matter how much water you put into the sink.  You flush the toilet you never have to worry about sewer smell coming back-up  and if the toilet gets clogged up you just plunge a few times and presto the waste is gone.
None of the above is true for your RV.  If you put too much water down your sink, you will over fill the grey water tank and the waste water will flow into your bathtub or shower.  If you leave your waste slinky hose hooked up with the open/close valve on you RV open you will invite sewer gas from the campground into your RV.  Because your toilet is on top of your black water tank there is a limit to how much waste you can put down there as well.  Also if it gets plugged up, plunging it will not help!
So what to do.  For the smell problem that might occur in the grey water tank I use Grey Water Tank Smell Killer.  It works.

As for the water back-up you should dump your grey tank every two days while camping or sooner if the water starts to back up.  This is the tank you can dump before you leave for home.
The grey water tank should be the last tank you dump before you head for home.  After dumping it you need to add approximately 1 gallon of clean water back into it and one of the grey water tank smell killers and you are good to go.
BLACK WATER TANK
Now the black water tank the scourge of RV camping.  There are a lot of does  and don't about this tank so let's get started.
No matter what you hear or read most all of the sensors that are supposed to tell you how full the black water tank is, do not work.  I have been told and it has been proven that the sensors mounted on the outside of the tank do seem to do a better job than those sensors that are inside the blackwater tank.  Most of the crazy ideas floating around about how to make the sensors inside the black water tank work also do not work.  To fix the problem of , how full is the blackwater tank.  So how do you know when it is time to dump the tank?  Look down inside the toilet and if you see blackwater, hear gurgling, and stuff floating, it's time to dump the tank.  So what can you do to improve how the black water tank works.
Use only quick dissolving toilet paper in this tank.  Toilet paper made just for RV is fine such as RV 2ply Toilet Paper or septic tank safe toilet paper.  But you can use just about any toilet paper that will quickly dissolve.  To test any brand of toilet paper to see if it can be used,  take a glass jar with a lid.  Fill the jar about 3/4 full and add a single sheet of your toilet paper to be tested.  Put on the lid and give the jar three quick shakes.  If most of the sheet of toilet paper is broken up and coming apart you are ok to use the toilet paper tested.

We have safe paper what next?  How about something to get rid of the smell and help break down the waste. I would suggest Black Holding Tank Deodorizer and Dissolver

This should be added to your black water tank regularly.  I add one tablet after each time I dump my black water tank and another during hot weather if there is a smell problem.
Oxy-Kem 


Here is another possible black tank treatment Oxy-Kem that comes highly recommended.  I have not tried it so I can't comment on how well it works, but I do plan to and will let you know.

Here is an all natural black tank cleaner that really cleans the tank as well as the sensors.  I have not tried it myself but all of the reports I am getting say it works.Unique Black Tank Cleaner



Do not dump your tank unless it is full or near full.  I know what you must be thinking but we never fill it over a weekend trip.  I realize that maybe the case but, you need to fill it up manually and dump it before you leave the park.  You do not need a hose or make this a big deal just flush the toilet and insert one of these things.
 Johnny Chock


Johnny Chock
          
Let the toilet run for approximately 10 to 15 minutes depending on how full your tank is.  If you can see the water in the black tank from the toilet that is full enough.  Remove the Johnny Chock and store.  Now dump the black tank like you usually do.  Add about a gallon or more of water (you can run the toilet with the Johnny Chock for 2 to 3 minutes and that should do it.  Drop in one of your black tank tablets and you are ready for the next outing.

Never leave the black tank drain valve open.  You are just asking for the smells of your neighbor's sewer to come up into your RV.  If you dump your holding tank to frequently you will have a build up of solid waste called the black pyramid of death (just an expression).  This is a problem you do not want and could cause an very expensive repair.  To prevent the "pyramid of death" you need to flush your black tank when it is at least 3/4 full and refill it so that there is some water splashing inside as you  drive back home.

One of the things you hear and I have tried is to add one cup of cheap dish washer liquid soap to break-up waste and Calgon to lube the inside of the tank.  Does it work?  I have been using it and have not seen much of an improvement.  I plan on using this in the grey water tank next to see if it makes a difference to that tank.
