I used to have a DE Filter years ago and it had an air bleed valve to make it easier to prime the pump.
I now have a Hayward Sand Filter. I was wondering if anybody has had the thought to add an easy open valve between the Multi-port and the Pressure gauge? One that blocked water from going into the pressure gauge while allowing air to escape the system so the pump will prime easily. Then close it off and open the inlet to the Pressure gauge to read filter pressure. I have seen water inside friends Filter Pressure Gauges and known that their pool guy got tried of waiting for the pump to prime after cleaning out the pump basket and backed the gauge out so air could escape, the only problem is that when the gauge is screwed back in to seal the leak, the high pressure forces water inside the gauge.
Will this work? Has anybody already done this and have a parts list? Is there a better solution? Is there an off the shelf solution?
