How to repair a rusting vent pipe?

Question

Hi, I would like some advice as to how I can repair a rusting vent pipe at the back of my home. It's a thin metal pipe that seems to have been rolled from a flat sheet, then crimped to seal into a cylinder. It has rusted along the seal, resulting in it separating and opening up, allowing smelly fumes to escape. Is there a product that could seal, then be painted over, such as some sort of tape? (Apologies for the slightly blurry photos, it's very close to the wall).

Thanks in advance.

Hello @Smithrj

Please note that plumbing work needs to be completed by a licensed professional for safety and compliance.

Thank you for sharing that photo of your vent pipe. It appears to be a plumbing vent pipe. Looking at the damage, it looks to be quite extensive. I recommend engaging the services of a licensed plumber to change the vent pipe to a PVC pipe to prevent rust from happening again. I don't recommend using any type of patch as this would only serve as a temporary solution.

Any changes that involve moving or reconfiguring pipework would be considered regulated plumbing work and would need to be carried out by a licensed plumber.

If you need further assistance, please let us know.
