I would like to know how to install and plumb a flush toilet in an RV that has a holding tank toilet now.?
Question:I live in a fifth wheel RV in a permanent spot and would like to replace the existing toilet with a regular house type toilet. I have a septic and a pipe open for it, but have no idea how to even start the plumbing from the rv to the septic pipe. Or what I need to change on the RV itself to make room for the new toilet. Someone said I have to take out the holding tank first, is this correct? I know somewhat how to plumb the water to the toilet, it's the pipe going out I am not sure of. Or what materials I need to get it started with. Any ideas or help would be great as I am a silly lady determined to do this myself. Thanks
Answers:
I'm going to assume the holding tank/toilet is a gravity operation, hence creating a natural flow to a holding tank. That holding tank must also have a gravity feed/release, or do you have to get it pumped?
I'm also trying to imagine the RV toilet being vastly different in size to a regular house toilet. (No offense, but it is a toilet)
The plumbing will have to be simialar or The size of household sewage drain,,,3 to 4 inches, have an exit point under or on the side of the RV, perhaps using an exit port already in existance? Then plumbed with that same pipe, to the septic. A decent plumbing supply house will be able to correctly supply you. There should however be some hardware, pipe, fittings, etc, already in existance that may be viable. Once a toilet is flushed, it's a relatively straight shot to City sewage disposal drains, and/or a septic. You might also visit a store that sells specifically to Mobile Homes,,,very likely a similar situation in construction and sizes. I live in a mobile with a regular size Standard toilet.
While I understand you say Permanent, you might want to consider (If it still rolls) that one day you might be moving the RV.

Your going to be facing two problems. Plumbing! The holding tank will have to be bypassed somehow or just left in the circuit. I really don`t see a need to remove it. It`s already plumbed to the outside and vented. But the real plumbing problem will be whether or not a typical flange can be installed properly.
The other problem is available space. More often than not, the layouts of RV`s are very stingy when it comes to "extra room". This a calculation you`ll probably have to make on your own.
Gotta ask!! Why fix something that aint broke?
In addition, what you have existing is more than likely less costly and more efficient.
