Why is there no water in my toilet bowl?

Difficult never came across this before. It could be a cracked bend and it's leaking out but I would have thought that would show up. Syphoning action more logical If all wastes go into the stackpipe [Large waste pipe serving the wc then one of them could be causing syphoning if the airadmittance valve is not opening you could then see a local plumbing shop and ask their advice on how to replace the valve or what ever makes it work..

This can also be caused by a minor blockage. If a piece of toilet tissue or similar is trapped in the U-bend, it can lie in the water and syphon the water out over night.

Either the bowl is cracked and leaking or there is a blocked air admitance valve which vents your drains
