Toilet water porting problem. What to do?
There are two toilets in my residence that smell badly.
Toilet #1: Discolored water in bowl. Stinky.
After scrubbing the toilet tank and bowl with a disinfectant, the problem seemed to go away for a day or two. Then the water in the toilet bowl was discolored again. And stinky. Stinky like poo, not like sulfur.
While shopping at Home Depot I asked about this problem in the plumbing department. A gentleman also shopping there concluded that this is a toilet water porting problem. The toilet flush does not take away all of the contents of the toilet bowl.
FYI The water in the toilet tanks is clear, and has no bad odor.
The sinks and tubs in the bathrooms with stinky toilets produce no discolored or smelly water. No other water using appliances in the entire house produce discolored or stinky water.
The toilet in a third bathroom does not produce discolored or stinky water.
Question is, what to do about it? Do the toilets need to be replaced? Thank you.
