### ⭐⭐⭐⭐⭐ Leak was too big for this sealer
*by K***G on October 20, 2024*

I can’t say that I blame the sealer for the size leak I was trying to stop. It was a long shot. In my case it didn’t work. However, I have a very slow leak in another unit so I will try it again. Better than $7200 for a new unit.
