Toilet seals aren't an issue unless you just dump bleach in the loo and let it sit there. So don't do that.
Holding tank gate valve seals, like Valterra's, are also probably made of Santoprene.
Wrong. After putting disinfectant in the fresh tank, you fill all the plumbing with it. It ends up in the loo and waste tanks. Duh.
You're right. For those once or twice a year RV plumbing sanitizing, the bleach/water solution will be in the system several hours each time.
I guess this is why we keep hearing so much about those catastrophic neoprene gasket failures in RVs.
