So glad we found this forum on toilets!
We have American Standard toilets with the yellow colored floats in our 4 year old house. 2 issues I hope you can help me with:
- We get dark brown algae-like stuff in all our toilet tanks (not bowls). I would install in-tank cleaner tablets but I heard it breaks down the components. What can be done?
- One of the toilets is extra noisy and seems to take a bit longer to refill. When I watch the toilet refill it appears that the yellow float has water leaking from underneath it into the tank. Is it simply broken and needs replacing? What is the yellow knob on the float for?
I should add, not sure it matters, that this toilet is connected to our in-hour fire sprinkler system too. It's obviously not the water supply for the sprinkler system but I remember the builder telling us the water supply to this particular toilet is connected to the sprinkler system. Maybe it slowly refills the water loss?
