 Rusting mounting toilet bowl bolts
Author: jeffb (FL)

The bolts that hold the toilet bowl base in the floor keep rusting away on me. I have replaced them twice; I see no water leaking what so ever or smell. I do drain my saltwater tank water changes in this toilet; but if it is sealed correctly water should never get to these mounting bolts; could it be my wife's cleaner; or is it leaking and I just don't see the water? Thanks Jeff

You should be using 5/16" solid brass closet bolts & nuts and snapping the caps on. The metal (steel) washers that come with the set should not rust if protected.

It could easily be the combo of humidity and acid cleaners causing the rust. Have you considered stainless steel bolts?

Bet you wish the plumber had used poly closet bolts.Maybe a good plumber could reset your toilet using them.

I know a lot of very good Plumbers and none of them use plastic closet bolts.

E plumber...YET...Like many you may not see a plastic bolt popping the metal flange off or cracking the bowl.They are not weak.And no not rust decay or give way.the square shank makes the install almost to easy.Never seen one of the bolts break.many pvc flanges though.
