stlgasman Posted June 2, 2008 Report Share Posted June 2, 2008 I have an inground spa pump with a two speed motor. If I leave the pump on low speed, it is fine. If I turn off the pump and then turn it back on, it won't re-prime. I found that if I close the valve from the hot tub and open the strainer cover and fill it with water, then have someone start the pump and then open the valve, it works. Is this a seal problem?

In some cases I have had pump seals be a issue with priming, even though they are not leaking. When you turn the pump off how fast does the water go down in the basket? When the pump is running, does it run with a full basket of water or does it have a lot of bubbles? Lots of bubbles in the basket could be a air leak.

stlgasman Posted June 3, 2008 Author Report Share Posted June 3, 2008 I have an inground spa and an inground pool with separate equipment. If I am working on the pool equipment and say I stop and restart the pool pump, the strainer will fill with water once I restart the pump. Granted the return pressure from the pool is higher (pool equipment below pool level). When the spa pump runs it never displaces all of the air but no bubbles appear that I can see.
