Question– “After flushing the toilet, the water in the toilet bowl is clear. The toilet is not used everyday, and the water in the bowl starts to turn a brownish color.”
Answer– In our opinion, if you’re not that concerned about it then we would recommend putting a bleach disc in the tank and this should keep the water clear. However, if you think you may have a bigger problem (ie. you’re seeing this problem in other areas like faucets or other bathrooms) then we would recommend calling a water quality company to come out to evaluate your water.
