Fixed my instantaneous water heat w/ this product

I have a $1200 instantaneous water heat that was fairly new and a PVC portion of the feedwater pipe inside the unit broke in freezing temperatures. The part was not replaceable and I didn't want to throw away a brand new water heater. I used JB weld on the interior fitting and JB PipeWeld on the exterior, and it works great--no leaks. Going on 1 month now with no problems.

Works Exactly Like It Says!

I used this to plug a dime-size hole in a plastic drain pipe. Let dry overnight just to be sure. Not a drop of water has leaked out since using this product three months ago. Just be sure to follow the directions carefully. I am a believer!
