Review on ComStar Copper Solder Plastic Container by Justin Hines

Update! January 2020 I only use this for emergencies now as I can't solder a whistle or use shark fittings at all. I had several leaks that only started after a couple of weeks. There were some good joints but not enough to trust this product. Would avoid if possible! Good product! I have used this for emergency repairs or in places where using a flashlight is dangerous e.g. B. in walls, or when I'm just lazy haha. I have used it on both regular water pipes and heating pipes with 100% success. Just make sure you clean both the fittings and the pipes like you sweat them. Also make sure fittings and pipes are DRY. If the seal fails, you can also simply heat them with a torch to separate them. I manage and maintain 70 family homes and this product has helped me solve several big problems. This also works with brass fittings and brass-to-copper connections. What's also great is that it installs in seconds and withstands full water pressure in a minute. I just ordered 2 more bottles for the winter.
