Poly tank repair

[twitch]

I have a 450 gallon Polly tank that has a 2 inch crack right near the bulkhead fitting. Just looking for thoughts in repairing ? Thanks

It is possible to weld with the right equipment. I have the equipment but have not tried.... Some equipment dealers are set up to repair.

I used a good plastic epoxy on a 10" crack in my pickup bed tank several years ago. it's doing great . It was a good $5 fix
I used a sharp wood chisel to v cut the crack like I was going to if it was metal and i was welding it then applied the epoxy on the outside only.
