The Waterway 400-5990 pump union is designed for compatible pump plumbing applications using a 2-1/2 inch union connection and a 2 inch slip outlet. This style is useful where the pump side must retain a larger union format while the downstream plumbing transitions into a smaller rigid line.
That size change makes this Waterway union especially practical in retrofit and replacement work where the pump connection and the existing plumbing do not match exactly in diameter. Using the correct union helps keep the connection serviceable while avoiding a less elegant stack of extra transition fittings.
For compatible pump repairs and plumbing updates, this Waterway union is a practical solution when a 2-1/2 inch union connection needs to transition into a 2 inch slip line.
