The Waterway 421-4071 reducer is designed for compatible plumbing applications that require a transition between 1-1/2 inch and 2 inch sizing. A reducer like this is useful wherever the plumbing system changes diameter and the transition needs to be made in a compact, purpose-built fitting.

Using the correct Waterway reducer can help simplify repair and installation work while keeping the plumbing layout more organized. This is especially practical in pool and spa systems where line-size transitions are common and fit consistency matters.

For compatible rigid plumbing systems, this Waterway reducer is a practical option when moving between 1-1/2 inch and 2 inch line sizes.
