Easy install. I used teflon tape and pipe dope for leak-free connections. No leaks or issues in the three months since I installed it. Review: At the time of the writing, very good quality! - As a retired HVAC tech I dealt with valves of various types for 38 years. Usually if you buy something like this off desertcart for about 1/2 of what most valve flush kits cost you expect some quality to be lacking. This is not the case with this valve flush kit at all. They might be made in a sweat shop on the other side of the world (or not) but the quality, fit and finish is very good. If I owned a business installing tankless water heaters I’d have no problem using this kit on my instillations. I can’t imagine paying $75-$90 for another flush valve kit because in my opinion this product is just as good. ## Features - Package Includes: 1 x hot isolation valve, 1 x cold isolation valve, 1 x pressure relief valve. - Easy to Use: These 3/4-inch IPS isolator tankless water heater service valves, rated at 500 WOG, come with color-coded handles for easy identification of hot and cold valves.
