Hi everyone, finally made the plunge and upgraded to a VSP After many long delays and challenges, we finally got it running last night.
Once i got it to prime, it worked great at higher speeds, and so much quieter than my old Jandy Stealth and achieved full prime (no air)!
I then decided to set it at a low speed, 1725 rpm for the night. After 2 hours there was a 2" bubble of air in the pump. After running almost 12 hours, the air bubble was down to the top of the filter basket.
I have searched around here and found that it seems well documented that this happens due to many possible sources, including dissolved gasses in the water, but my question is has anyone else seen this lately (all posts were 2+ years old). My other question is should i be concerned if that if i run at low speed for multiple days, will the pump ever fully loose prime and be pulling air?
Finally, has anyone come up with a best practise for speeds/timings? Should i run ever 2 or 3 hours at a higher speed for 15-20 mins to purge the air?
