Glue for Joining over flow pipe from flush tank

[Brett2021]

what glue is best for this..? I thought to use super glue first then saw these items.
I assume below listed ones are specific to this joining purpose and better than using super glue..? Solvent cement or PTFE liquid is suitable for this..? Please help

Pipes that connects doesn't have any grove/thread as shown below..

PVC solvent cement shown below? OR

this PTFE Liquid??

Solvent cement.

You want the PVC cement. The PTFE is for sealing threads. Superglue dissolves eventually exposed to water.

Repeating yourself again Harry!

Thanks both. Got a good idea now. Thanks to this forum.

This one is sorted , but now another small issue.

Since I opened overflow pipe from flush cistern while fixing the Pan connector, now that joint is leaking.

I put similar washer at both inside and outside and applied some solvent cement on both. Hope this fix it.. If it still leaks I am scr**ed!!

Any suggestions..?

You don’t put solvent cement on a rubber washer, and you would have only needed one washer on the inside. If silicone was used previously, or if there’s detritus the that will prevent it sealing correctly.

Though I did this wrong way somehow no leaks , so atleast for the time being I am saved.

I would recommend that you take that washer out and replace the washer, the solvent weld glue will have compromised/damaged/hardened the washer and it may leak again over the longer term.
