The Jabsco Par-Max 1 series pumps are available as automatic and manual demand pumps. The 710237 will automatically turn on when a fixture is opened and turn off when fixtures are closed. When starting up an automatic demand pump with a completely dry system allow time for the demand pump to fill the system. Open a faucet, allow air to vent and close faucet when water flow is steady. Faucet strainers and aerators should be cleaned regularly.
