Dodgy plumbing?

Hi all,

About a year ago I've got a small toilet-shower installed under the stairs.
Yesterday the shower drain got clogged and I have used some chemicals, hot water and finally a plunger to unclog it. After using the plunger the hole drain pipe has come off . As you can see in the picture it was only hold by silicone and nothing else. I am not a plumber but in the past I have installed sinks and all drainage systems were hold together with a long screw holding top and bottom parts together and silicone only used to seal and not to hold bits together. Is the drainage system in the picture normal?

I would say the top piece, shown upside down there, should be screwed into the trap below?

Bloody hell you are right, I have just checked and the top bit has broken in two and the screw is still inside the pipe!.
Easy fix I think. Thanks!!

Is there any way you can see the trap somehow once you’ve sorted it, to check for leaks?
I like to silicone both sides of the tray - belt and braces!

Yep, with a key similar to this

I can't check for leaks unless I remove the floorboards. I will put silicone on both sides and hope for the best. I think I left chemicals for too long and somehow they have damaged the plastic

Just need to find a new flange to fit, then hook something in the trap to pull it up square enough to start the thread

Yes it looks like the way forward, not a brilliant system though

Do clean all of the old silicone off before applying more!
Hopefully the threads will locate and pull the trap up nicely but leaking traps spook me big time - at least you are on the ground floor.
I have used an endoscope to check for leaks at times - not ideal but the application of laminate makes jobs like this so difficult.
Be lucky
