I have been having a recurring problem in my Drake II toilet. There is apparently a biofilm growth in the siphon area of the bowl. After flushing you can see small to medium fibrous looking deposits exit from the siphon hole as the toilet is refilling. I have tried all of the usual remedies - bleach, enzymatic/bacterial cleaners, hydrogen peroxide, etc. with no luck. It keeps coming back. I've also tried to get into that area with a brush, but I really can't do it effectively.
We have 3 other Toto toilets in the house and do not have this problem any where else. Also the tank is completely clean, so the problem isn't in the water coming in or from the tank. I'm at the point of replacing the toilet unless I can figure this out. It's very unpleasant to have things float up from the bottom of the bowl after you flush - and this is the main floor guest bathroom.
Any suggestions?
