I have an older Hayward PowerFlo that I'm trying to test by connecting a hose into the water and seeing if any water shoots out the other end (short hose pointing away from the deck). So far nothing other than some prime comes out. If I disconnect the hose and cap my hand over the intake for a few seconds I do not feel much if any vacuum. Is there a way I can test the pump's throughput other than what I'm currently doing?
Sand filter and other parts are not ready yet. I can run my pool hose into the water but that about it. Thanks.
