The Zodiac and Jandy 180 degree check valve is designed for compatible plumbing applications requiring a 1-1/2 inch slip connection on one side and a 2 inch spigot connection on the other. A check valve is useful because it helps control one-way flow, preventing unwanted backflow that could interfere with normal system behavior.This replacement is especially useful where the plumbing layout depends on this specific slip-to-spigot transition and a straight-through 180 degree configuration. Using the correct valve helps keep the installation cleaner and preserves the intended function of the line.The 7235 is a practical plumbing component when a compatible system needs a one-way check valve with the proper connection mix and straight-through orientation.
