I installed a CST743E myself and it's much better than the 14 years old toilet it replaces. But it wouldn't be a fun DIY if everything is perfect, would it?
After pushing the flush lever, there is a short sucking sound. The same sound happens again when the flush is done and is a little louder. I'm guess it's the flush valve but it's brand new so it shouldn't be defective. I've also tried to adjust the supply line valve and the water level screw but they didn't make any difference. Is it because the water pressure is too high?
Do anyone else with 743E have similar problem? Thanks,
Kevin
