Removing black tank for septic system

to do it correctly you'd need to know the plumbing rules. and, if you take out the black water tank at some point i'd think you will sale the trailer and it won't have a tank...replacing it would probably cost $1300-2000.

i'd suggest just leaving the tank alone and figure out a dumbing schedule, i.e. every two weeks or so.

emoving tank could also cause smells.

I vote with Ed. Bunch of work for little return.

Lots of people who have their trailers on a permanent site at our RV park have done it.
It is relatively simple to drop the tank and take it out,but the big consideration is hooking up the vent pipe to the sewer pipe.
I'll probably be doing it with our 2018 trailer as soon as I have a problem with the toilet

Why would you want to do it, what are the advantages?

^Hes going to use it as a cabin and not move it.
To the OP, you doing the same with the gray tank or still plan on dump ing it?

It would just depend on the configuration of things once you pull the tank. Every trailer is going to be setup differently so it's tough to give advice. The biggest headache is going to be disturbing the underside to remove the tank and rework the waste piping. I don't think it's a ridiculous idea as long as you are going to keep the trailer stationary for a long time. Holding and dumping every week or two would get old quickly. Once you setup the waste piping correctly there's no reason you can't install a residential toilet.

Just remember the only two things that matter when doing the work - "stuff" only rolls down hill and don't chew your nails :)

Yes i gather that i was just wondering if there are advantages other than not having to dump the tank. My father inlaw just moved into one (86 years old!) and is loving it for two years. He fills the tank halfway or so and then dumps which is about once per week.

No more dumping
No more flushing out the tank
No more chemicals

the first bit of trouble I have with mine I will do it too

Thank you,

I thought I knew something about TT but coming from a FEMA TT with a residential toilet and a septic tank I'm used to once I was done with my business and paper work it was gone, never to be seen or smelled again. Using this new TT again as a stationary unit I'd like the same experience and do not want to worry about fumes seeping back inside or dealing with black tank maintenance if I don't have to.

As far as resale, I'll keep the tank and try to make any work I do reversible but I'm not to concerned about the next owner as much as I am the current owner.

Not sure if I'd need to with the gray tank. My thought is to just leave it open.
