toilet parts

[Gerianne]

yesterday, there was "Niagra Falls" in my bathroom from the back tank.
maintenance men came, replaced a number of parts and now I have a "singing toilet" every half hour.
I am still waiting for a complete resolution.
when the water + air aren't working together, there is an imbalance.
I have learned quite a bit about Air Conditioning problems and solutions when I have them.
Plumbing problems are a bit more complex.
