I have a Toto Soiree toilet (CST 964 CF). Some minutes after flushing it, and after the toilet has filled, it will make a sound like "goosh, goosh, goosh, goosh". This sound continues for 4 - 5 seconds before stopping. A few minutes later this sound will repeat, until I flush the same toilet again. The sound is most likely to occur when the flush handle is held down to evacuate solids completely, though it occasionally happens with a quick flush, too. This sound is clearly made by water in the pipes, but I cannot figure out what the cause is. Could a faulty valve (Cyclone 528) be causing this problem, or should I look elsewhere? Thanks for your advice!
