Shurflo Pumphead Kit for 4158 Series Aqua King II Pumps

The Shurflo Pumphead Kit for 4158 Series Aqua King II Pumps supplies pressurized fresh water to compatible onboard fixtures such as faucets and showers. Its multi-chamber diaphragm design responds to demand as fixtures open and close, providing a practical pressure source for boats with one or more fresh-water outlets.

A built-in bypass function allows the pump to accommodate lower flow demand with reduced cycling and can eliminate the need for a separate accumulator in appropriately designed systems. Marine-oriented motor construction and included connection hardware support installation in the humid, vibration-prone onboard environment.

Confirm electrical supply, circuit protection, tank outlet, inlet strainer, plumbing size, pressure compatibility, mounting position, and service access before installation. Sanitize potable-water plumbing as required, protect the pump from freezing, and test every connection for leaks while cycling fixtures through normal operating conditions.
