Mainline - Model ML-FR4 -Fullport Retro Valve

Unlike other valves this valve has a minimal fall 3/8" through the body which means it`s easier to install. Simply cut out enough pipe for valve and simply drop in and connect to plumbing system. This can be done in as little as 24"of excavation, if utilizing existing building cleanout. All other valves have greater falls through the body and require at least 4-5 feet of concrete breaking just to make up the fall through the body. NO 2-foot rule as in other valves.
