The volute on my Polaris pump cracked the other day. Happened to be home when I saw the water spraying everywhere. Replaced and started up my 2.0 HP filter pump. Was having a little issue with getting a solid prime but it’s normally got a few bubbles blowing through my returns. After about 10-15 mins of semi-priming the pump just turned off. I checked the impeller and found no obstructions. I used a drain bladder while it was off to try and clear any other debris. Turned pump back on and it fired up with a not of trouble priming. Turned it back off after 30 seconds and filled the basket with water and tightened the lid. I stuck a drain bladder down a return line in one of my skimmers. Turned pump back on and it fired up. I was able to get a prime after a minute or two. Came back out a few mins later and prime was lost, but then I heard it catch again and it primed but blowing a lot of bubbles. A few mins later the pump cut off again. No visible leaks in my piping. I did notice the basket on the pump housing was whining a lot after it turned off. When I opened the cap the pressure released and it stopped.
The pump is about 6 years old. Is it overheating from not getting a prime or is it time for a new one?
