if you have a problem getting pump to suck antifreeze disconnect hose and reverse pointed rubber hose gasket ,then replace hose.this will push against check valve allowing pump to suck better,dont forget to reverse filter gasket when done(point side out).if you dont when you use pump in spring it will shoot water out of freezeguard port.in spring leave hot water tank on bypass,hookup hose to city water supply and run all hot and cold lines to get antifreeze out of all lines,then take hw heater off bypass,put plug in and fill
