Can you slide PVC pipe over a galvanized pipe to stop a leak?

Yes, you can slide PVC pipe over a galvanized pipe to help stop a leak, but it’s not a permanent solution. Ensure the area is clean and dry before applying a suitable sealant or adhesive to create a watertight seal. However, it's generally recommended to repair the leak properly by replacing or fixing the galvanized pipe to ensure long-term effectiveness and safety.
