The unibody gate valve is commonly used to stop water from draining out of your spa so that heaters, pumps, control systems and more can be replaced with ease. If you spa does not currently have gate valves we recommend installing them especially when replacing your control system. The Magic Plastics 0517-20 gate valve is for use with 2" plumbing and has a spigot connection on one side and union connection on the other. This allows the installer to glue plumbing tightly against the unibody valve on one end and glue plumbing into the other end.
