Problem with toilet not flushing

[kid2]

When the toilet is flushed, the bowl fills up with water then empties below the U bend and the wash basin plug gurgles.
If I turn the basin tap on, the toilet bowl fills to its normal level quickly.
If I don't turn the tap on, it fills but a bit slower.

When the soil pipe cover is removed (photo attached), the toilet flushes like it should.

Thank you for any suggestins you may have.

Blockage downstream. Check manholes.

Anything been flushed that shouldn’t have?

 

[kid2]

Not that we're aware of.
We have 3 toilets but only this one is not flushing as it should.

As per @Hugh Jaleak then, check the manholes.

Make sure you've eaten first!

We planed to investigate today which wouldn't have been easy due to our kitchen extension, but the toilet has started flushing without any issues!

Could there have been a slight blockage that cleared itself?
Is there anything we can do to prevent it happening again?

Kitchen extension?
Has the manhole been built over?

Yes, the kitchen extension was done before we bought the house. We can still access the manhole if necessary.

Well, I have one in my kitchen extension with a sealed manhole in the tiles.
It needs cleaning out about once every couple of years.

Possibly, if waste has backed up and weight behind blockage has caused it to give, then quite possible it's cleared itself.

Not really, apart from don't put anything down the WC you shouldn't, (should only be the 3 P's, Pee, Poo and Paper), and avoid putting cooking fat down the sink. Let it cool and put in food waste or refuse bin.

Keep an eye on situation, any changes, e.g. toilet backing up, gurgling sinks/showers etc., then I'd be prepared to start investigating further, as possible it's either still blocked or has blocked again.

Not venting so sucks water out of pan .

We've been here for 11 years and so far, not had any issues. We'll keep an eye on it and will investigate if need be.

It's mainly shower, sink, washing machine and dishwasher fat that clogs it... Kids thinking sink is a food bin grrrrr!
