How can I fit this more securely?

[Homervanderjazz]

So I was up in the loft and saw the above, I think it’s from the extractor fan in the bathroom... as you can see it’s not sitting snugley into the pipe and seems to be hanging on by cable ties.

Any advice on how to fit this back in? Should I just use more cable ties to secure it back somehow? Thanks for any advice.

The white pipe isn't long enough so you'll always be fighting it whatever you try to use. Get another length from screwfix so that you can extend it, then zip ties, or I prefer gaffer tape.

Personally if that was my place,removing and inverting the swept tee so air flow continually rises would be considered although that will need some more alteration.

To simply join the dangling flexi ducts more securely,these adaptors have been available in the past https://www.axminster.co.uk/soil-pipe-adaptor-900063

The soil connection side of the adaptor is slightly oversized for your 110mm pipe but with some silicone and a couple of self tapping screws in each adaptor they will hold the firm.

Join the flexi duct to the spigot adaptor with duct tape
