Sometimes the toilets are installed with "carriage bolt" head machine screws that are adhered in place with Sealant during installation. (Mine was.) If that is the case, a wrench won't work inside. If you do have a 6 point head on the bolt you're lucky. When I replaced my toilet, the threads were corroded, (like most,) and I wound up taking a 3" air grinder to them to remove them. I will offer a caveat on this procedure...You will undoubtedly dig into the plastic of the toilet base if you use this, or any type of saw, but since I was replacing the toilet outright, it didn't matter as it went in the trash anyway, when I installed my Sea-Land 511 Traveler porcelain bowl toilet to replace the crappy Thetford plastic piece of junk the trailer came with. (Note: Not a Scamp
, but a Casita
Also, not sure about the "wax ring" as my toilet had a rubber seal gasket, but then, it's not a Scamp
, so I'm not sure what you'll find when you get it off.
