“T” CONE EXPANDABLE PIPE PLUG, 3-1/2”

Common Failure Signs

• Visible leaks or drips from pipe joints
• Loss of pressure in plumbing or gas lines
• Need to isolate pipe sections for repair
• Water or gas flow where it should be stopped

Before You Replace It

Before replacing or installing the pipe plug, verify the pipe diameter matches 3-1/2” and inspect the pipe interior for debris or damage that could prevent a proper seal. Confirm that the leak or flow issue is localized and that sealing this section will resolve the problem. Testing pressure levels before and after installation helps ensure effectiveness.

When Replacement Makes Sense

Replace the pipe plug if it shows signs of wear, cracking, or if it no longer expands securely to seal the pipe. Also, replace it after extended use or if it has been exposed to harsh chemicals or extreme temperatures that could degrade the material.

DIY or Call a Technician?

Installing this pipe plug can be a manageable DIY task if you have basic plumbing knowledge and proper tools. However, if you are unsure about pipe sizing, pressure ratings, or if hazardous gases are involved, it is safer to call a professional technician to avoid injury or further damage.
