A pressure switch tube is useful because it helps transmit the pressure condition to the switch

A volute is useful because it helps direct water through the pump housing and into the discharge path

A union nut like this is useful because it helps clamp the union assembly together while still allowing the connection to be opened for future service

Waterco Baker Vertilever Valve Piston Assembly (31B0005) poolparts A pressure switch tube isThe Waterco Baker Vertilever valve piston assembly is designed for compatible valve applications where the main moving piston section needs replacement. A piston assembly is useful because it is one of the central functional parts responsible for the valves controlled movement and flow routing behavior. This replacement is especially useful when the original piston is worn, damaged, sticking, or no longer moving with the precision the valve needs.
