Building / Plumbing noise

[tacogrande]

In a building that is twenty years old (since remodeling), there is now some plumbing noise when toilets are flushed. This is the largest use of water within the building, so it is the water lines making the noise as they fill the toilet tank, not sewer. Any idea what could be causing such?

The toilet fill valves are designed to make a noise so that you know when the valves are leaking. If the noise is about the normal running water level, see the link:

I think that it is a toilet's fill valve problem. When the diaphragm gasket inside the top cap of the fill valve goes bad, it loses elasticity and becomes hard. When it tries to shut off, it bounces in micro vibrations sending a shock wave back into the piping. So you will check toilet's fill valve or contact with any plumbing service provider company for solving this problem. visit
