Advice/tips on changing a toilet? Grey water drain cleaners?

Hey everyone,
I have a two fold question. My first question is about replacing a toilet. I have a 19 ft Hi Lo from 1985 that I am about to swap out the original toilet for a new one. In fact I'm installing this toilet.

I've changed many a toilet in a standard home and I'm wondering if there are any differences? For example do I need a wax seal? If so is it a special wax seal or the standard will work?

Also does anyone know what the grey semi flexible piping is called? The entire trailer is plumbed with it and I need to make some changes to it so I can install the new toilet. The flush pedal is on the opposite side on my new toilet.

It appears really straight forward but past experience has taught me that with RV's it rarely is as it appears.

Second question is about using drain cleaners for my grey water lines. My local hardware store has a formaldehyde free drain cleaner for septic systems that uses only natural enzymes. It says it's safe on any surface that isn't harmed by water. Anyone have any experience with this? I'm just trying to avoid having to special order the drain cleaner and pay shipping on it.
Thanks in advance!
  • I would avoid Sharkbite-style fittings. I've personally not used them, but people on the Airstream forum have found that the only thing separating you from disaster is one O-ring which tends to get eaten over time. Some of these fittings are getting better, using two O-rings, but the issue does still remin.

    The Flairit fittings don't use O-rings, so seem to be something good for the long haul.

    Of course, the best way to do it is to use Uponor PEX tubing and expansion fittings which stay on for good, but the tool for those is very expensive.
