Review on 🔧 Rectorseal 45322 Freeze Leak Repair for Enhanced SEO by Guerdon Draper

I connected one end to the syringe with no problems. I bled the hose adapter so it was filled with the green liquid. I heard a low hiss as the side of the drain pipe gave way and then stopped. So far so good. The clean side of the connection. The AC is running at full power as stated on the box. Upon squeezing with the caulking gun, the green liquid began to bypass the plunger and fill the back of the syringe. I can't say how much, and I suspect little, if any, entered the AC system.
