Blocked soil pipe after installing replacement toilet

[AntEpping]

Hi - I'm not an expert but wondered if anyone might be able to assist. I've replaced an old toilet with a new one. I've used the same water inlet pipe, and have just replaced the right angled soil pipe connecter (110 at toilet end to a 97-107 connector end to existing soil pipe). It's secured down, and works OK, apart from the toilet water after flush is draining away slowly after flush, like there's a block somewhere in the soil pipe.

It's connected to the downstairs main soil pipe that also has 2 sinks, a dishwasher and bath connected. If I drop a lot of water down one of the sinks (bucket for example) then I'm getting bubbles in the toilet, and vice versa.

If anyone could point me in the right direction of how I might have gone wrong, or if it just sounds like a blockage in the main soil pipe, i'd be really grateful. Thanks!

Do you have a picture of the side of the old toilet

Could be an air problem

Hi this is the old toilet (not sure if this is what you meant) and I’ve included a photo of the new toilet I’ve connected

Sorry Shaun - is this better? It was very old with rusted bolts which is why it’s cracked at the bottom

Spot on

No it’s a stnd pan so in theory should be fine nothing accidentally fell down the pipe ?

No - that was sort of impossible as the soil pipe (terracotta one) was already there and horizitonal - so I just attached new connection to it.

What’s strange is that at first I bought the wrong connection, and the toilet was too far out from the wall, and it flushed absolutely fine. But I changed the connection between toilet and soil pipe to the one shown, and now I’ve got this issue.

There wasn’t any instruction book in it tbh I think your going to have to pull it off and check etc
