The best way to sum this product up is WOW!! Copper bathroom water line broke and I had to a remove section of drywall to get to pipe. Breaks were at the bottom of pipe near concrete foundation. Yes, breaks (2) one hole was about the size of the end of a pencil tip (good steady stream). The other hole, opposite side of copper line, was a pin-hole spray (a pretty good one). Also we have really really good water pressure here in town. I really didn't think it would work, BUT IT DID!!
